Abstract The aim of this article is to draw the attention of scholars of ancient medicine to the need to consider the works of humanists in interpreting and editing medical treatises. Because humanists, especially those who had studied medicine and botany in the Italian universities, had acquired both a theoretical knowledge of ancient writings on medicine and a practical expertise in botany that allowed them to identify the plants mentioned in the major ancient sources such as Dioscorides, Theophrastus, Pliny and to understand their lexical uses in the Byzantine treatises on uroscopy. Such is the case for the word chyménè, which is nowadays completely misunderstood, as our examination of Theophilus Protospatharius’ De urinis (ca. seventh-ninth century) will show. That word, while obscure to the first translators of this treatise, such as Ambrogio Leone (1519), was correctly interpreted by the humanists Onorio Belli (1593), Claude Saumaise (1629) and Bodaeus de Stapel (1644), who were also the first to show us that the Latin version of Theophilus’ treatise on Urines had become corrupted in the course of the centuries.

Abstract:
Botanic gardens have not changed much from the day they were established until today. Generally, a botanic garden is devoted to the collection, cultivation and display of a wide range of plants. In principle, its role is to maintain a documented collection of living plants for the purpose of scientific research, conservation, display and education. However, one of the major functions of botanic gardens is being ignored, that is, to instil and generate the sense of oneness between man and nature. Basically, man is inclined to destroy nature rather than preserve it for commercial reasons. Efforts to curb this problem have not been successful. Educational programmes conducted by botanic gardens to educate visitors with scientific information regarding nature have not been adequate. They have neglected the human dimension of nature which is so important in developing a sense of oneness between man and nature. Where and how to derive the human dimension from? This paper will explore the human dimension of plants as discovered in poetry written specifically about the human dimension to reveal the closeness between man and nature. Muhammad Haji Salleh, a well-known Malaysian poet, has written poems about plants that are common in tropical botanic gardens. Textual analysis has been used to study the poems and has uncovered the human dimension in them. This discovery gives insight into a new model of botanic gardens as the manifestations of botany (science of plants) and poetry, thus providing the human dimension absent in previous models. According to this new model, then, botanic gardens have a new role to play in providing the educational programmes for the public. Keywords: poem, human dimension, botanic garden, nature Abstrak Sejak dahulu hingga ke hari ini, taman botani tidak banyak berubah dari segi fungsinya. Umumnya, taman botani memberi tumpuan pada koleksi, kultivasi dan pameran pelbagai jenis tumbuhan. Pada prinsipnya, taman botani berperanan memelihara koleksi tumbuhan hidup bagi tujuan penyelidikan saintifik, konservasi, pameran dan pendidikan. Walau bagaimanapun, salah satu fungsi taman botani telah diabaikan, iaitu menanam dan memberi kesedaran tentang kesatuan antara manusia dan alam. Atas alasan komersial, manusia cenderung untuk memusnahkan alam daripada memeliharanya. Usaha mengawal masalah ini masih belum berjaya. Program pendidikan yang berasaskan informasi saintifik yang dilaksanakan oleh taman botani untuk mendidik para pengunjungnya didapati tidak mencukupi. Dimensi manusia yang ada pada alam yang menjadi satu aspek penting kepada penyatuan manusia dengan alam telah diabaikan. Di mana dan bagaimana untuk mendapatkan dimensi manusia itu? Makalah ini meneroka dimensi manusia yang ada pada tumbuhan khususnya pokok melalui puisi-puisi yang dicipta oleh Muhammad Haji Salleh, seorang penyair terkenal di Malaysia yang telah menghasilkan puisi yang berkaitan dengan pokok-pokok yang terdapat di taman botani tropika. Analisis teks telah digunakan untuk mengkaji puisi-puisi tersebut. Kajian dapat membuktikan bahawa wujud dimensi manusia dalam puisi-puisinya. Dapatan ini telah memberikan satu wawasan baharu tentang satu model taman botani yang menjalinkan antara botani (science of botany) dengan puisi. Dengan demikian, model baru ini memberikan dimensi manusia kepada taman botani yang tiada dalam model-model taman botani yang ada sekarang. Dengan model yang baru ini, taman botani mempunyai peranan baharu dalam memberikan pendidikan kepada masyarakat umum. Kata kunci: puisi, dimensi manusia, taman botani, alam

Abstract:
The university in Vilna (in Polish: Wilno, now: Vilnius, Lithuania), founded in 1579, by Stefan Batory (Stephen Báthory), King of Poland and Grand Duke of Lithuania, was a centre of Polish botany in 1780–1832 and 1919–1939. In the latter period the university functioned under the Polish name Uniwersytet Stefana Batorego (in English: Stefan Batory University). It comprised six departments connected with botany (General Botany, Pharmacognosy and Cultivation of Medicinal Plants, Plant Taxonomy, Botanical Garden, Garden of Medicinal Plants, and Natural History Museum). There worked such distinguished scientists, as: Jakub Mowszowicz (1901–1983), phytogeographer and phytosociologist; Jan Muszyński (1884–1957), botanist and pharmacist; Bronisław Szakien (1890–1938), cytologist and mycologist; Piotr Wiśniewski (1881––1971), physiologist; and Józef Trzebiński (1867–1941), mycologist and phytopathologist. Ca. 300 publications (including ca. 100 scientific ones) were printed in the period investigated, dealing mainly with morphology and anatomy, cytology, plant physiology, floristics (floristic geography of plants), systematics (taxonomy) of vascular plants, mycology and phytopathology, ecology of plant communities (phytosociology), as well as ethnobotany, and history of botany. Stefan Batory University was also an important centre of teaching and popularization of botany in that region of Europe. The aim of the article is to describe the history of botany at the Stefan Batory University in 1919–1939. Botanika na Uniwersytecie Stefana Batorego w Wilnie (Vilna, Vilnius) (1919–1939) Abstrakt Uniwersytet w Wilnie (w języku angielskim: Vilna, obecnie: Vilnius w Republice Litewskiej), założony w 1579 r. przez Stefana Batorego, króla Polski i wielkiego księcia Litwy, był ośrodkiem polskiej botaniki w latach 1780–1832 oraz 1919–1939. W tym ostatnim okresie funkcjonował pod nazwą Uniwersytet Stefana Batorego (w języku angielskim: Stefan Batory University). W latach 1919–1939 zorganizowano następujące zakłady związane z botaniką: Botaniki Ogólnej, Farmakognozji i Hodowli Roślin Lekarskich, Systematyki Roślin, Ogród Botaniczny, Ogród Roślin Lekarskich oraz Muzeum Przyrodnicze. W ośrodku wileńskim pracowali wybitni uczeni, m.in. Jakub Mowszowicz (1901–1983), fitogeograf i fitosocjolog; Jan Muszyński (1884–1957), botanik i farmaceuta; Bronisław Szakien (1890–1938), cytolog i mykolog; Piotr Wiśniewski (1881–1971), fizjolog oraz Józef Trzebiński (1867–1941), mykolog i fitopatolog. Badacze roślin ogłosili drukiem ok. 300 publikacji (w tym ok. 100 naukowych) dotyczących głównie morfologii i anatomii, cytologii, fizjologii roślin, florystyki (florystycznej geografii roślin), systematyki (taksonomii) roślin naczyniowych, mykologii i fitopatologii, ekologii zbiorowisk roślinnych (fitosocjologii), a także etnobotaniki i historii botaniki. Uniwersytet Stefana Batorego był również ważnym ośrodkiem nauczania i popularyzacji botaniki w tym regionie Europy. Celem artykułu jest opracowanie historii botaniki na Uniwersytecie Stefana Batorego w latach 1919–1939.

Abstract:
The creators of Sydney's botanic garden were a varied group of people with diverse agendas and interests, only some of whom saw themselves as men of science. While several were trying to advance botany, others were more concerned with self-advancement or financial gain. Yet they collaborated, almost unintentionally, to found Australia's first scientific institution. Exchanges of plants were crucial to forming and maintaining the relationships between these different figures. Studying these exchanges allows hitherto neglected figures to take their place in the garden's story alongside well-known ones. This study also takes issue with the notion that British colonial botanic gardens were established as part of a botanical empire, with Kew Gardens at its centre. It also seeks to extend Susan Leigh Star and James R. Griesemer's idea of ‘boundary objects’, by suggesting that relationships based on barter, gift-exchange or patronage rather than cash played a key role in mediating between the participants in colonial scientific institutions.

Abstract:
To examine claims that the role of botanical art in systematic botany is diminishing because of advances in photography, this review considers relevant literature and includes a quantitative analysis of trends in modern journals, monographs and floras. Our focus is on southern hemisphere systematic botany because, relative to the northern hemisphere, this is poorly represented in modern reviews of botanical art and photography. An analysis of all digitally available papers in Nuytsia, the Journal of the Adelaide Botanic Garden, Muelleria, Telopea, Austrobaileya and Systematic Botany established that, although photographic illustrations have increased since 2000, botanical illustrations have not always diminished. The cause of these trends is unknown, but it is likely to be due to several factors, including sourcing funding for production of botanical illustration, editorial preference for the use of illustrations or photographs, author preference for either illustrations or photographs, and moving to online publication, with no charges for colour reproduction. Moreover, the inclusion of botanical artists as co-authors in some scientific publications signals an ongoing and important role. Botanical illustration brings sharp focus and meticulous attention to detail regarding form and structure of plants. Photography is useful at the macro-scale for habitat and whole-plant traits, as well as at the micro-scale for anatomical textures and ultrastructure. These complementary approaches can be important components of taxonomic discovery, with the potential for a new role in modern trait analysis in molecular phylogenies.

Histoires des noms des plantes : le Jardin médicinal d’Antoine Mizauld est une thèse en littérature et en langue françaises sous la direction de Fleur Vigneron.Cette thèse s’inscrit dans le cadre d’une convention CIFRE entre l’Entreprise Herboristerie Au temps des fées et l'équipe Imaginaire Socio-Anthropologie (ISA) de l’UMR Litt&amp;Arts 5316 de l’Université Grenoble Alpes. Les buts de cette convention sont d’effectuer des recherches sur l’imaginaire des noms des plantes médicinales et de participer au développement de la marque Comme des tisanes, de l’Herboristerie Au Temps des fées.Dans un premier temps, nos travaux de recherche se concentrent sur l’édition du Jardin médicinal d’Antoine Mizauld, un traité de médecine du XVIe siècle expliquant les vertus des végétaux avec des histoires mythiques et des anecdotes divertissantes. Le texte établi par nos soins est suivi de glossaires mettant en avant les noms des plantes médicinales et des définitions pratiques pour mieux comprendre les propos d’Antoine Mizauld. La seconde partie est un commentaire du Jardin médicinal qui analyse la posture de l’auteur et la formation des représentations des plantes médicinales, en mettant l’accent sur l’usage des mythes et les utilisations actuelles des plantes dans l’industrie du bien-être. La dernière partie propose une analyse de sept plantes médicinales (appellations françaises, étymologie, usages et mythes), afin d’étudier leurs traits archétypiques et d’établir leur histoire culturelle.Grâce à des approches synchronique et diachronique, cette thèse présente une théorie sur la formation des représentations des plantes médicinales dans la langue française. Elle permet aussi de mettre en place un protocole innovant de création de biens ou de services, en usant des recherches en lettres et des méthodes de l’imaginaire<br>Stories of Plant Names : the Jardin médicinal by Antoine Mizauld is a PhD thesis in French literature and French language supervised by Fleur Vigneron.This thesis is part of a CIFRE agreement between the company Herboristerie Au temps des fées and the Imaginary Socio-Anthropology (ISA) component of the CNRS 5316 Litt&amp;Arts research unit at the Grenoble Alpes University. The aims of this agreement are to carry out researches on the images of names of medicinal plants and to participate in the development of the brand Comme des tisanes, by Herboristerie Au Temps des fées.At first, our research works focus on the edition of the Jardin medicinal by Antoine Mizauld, a sixteenth century medical treatise explaining the properties of plants with mythical stories and entertaining anecdotes. These works are followed by glossaries pointing out the names of medicinal plants and practical definitions to better understand Antoine Mizauld's words. The second part is a commentary on the Jardin medicinal which analyses the position of the author and the formation of images of medicinal plants emphasizing the use of myths and current uses of plants in the wellness industry. The last part presents an analysis of seven medicinal plants (french designations, etymology, uses and myths), in order to study their archetypical traits and to establish their cultural history.Thanks to synchronic and diachronic approaches, this thesis presents a theory about the formation of images of medicinal plants in the French language. It also allows to implement an innovative protocol to create goods or services, by using researches in literature and methods of studying images

Abstract:
De nos jours, l’identification automatique des espèces de plantes par l’analyse d’images, devient incontournable pour faire perdurer, standardiser voire approfondir les connaissances relatives à la communauté végétale. Cette thèse aborde le problème d’identification automatique des espèces de plantes en utilisant les images de feuilles. Elle s’attaque à deux principaux challenges: Le premier challenge est le grand nombre et la large variabilité de la morphologie foliaire des espèces et le deuxième challenge est la variabilité intra-espèces qui se manifeste localement au niveau de régions particulières des feuilles. Pour pallier à ces deux problèmes, un retour à la botanique et notamment aux concepts botaniques foliaires a été établi pour définir une structuration automatique des feuilles à deux niveaux: Le premier niveau concerne un schéma de catégorisation selon les deux concepts botaniques “arrangement” et “lobation”. Le deuxième niveau consiste à définir les parties sémantiques qui composent la feuille. L’approche de la thèse s’articule autour de deux principaux volets: Dans le premier volet, nous nous intéressons à mettre en place cette structuration guidée par la sémantique botanique en définissant des propriétés géométriques simples corrélées avec les définitions et les observations botaniques. Dans le deuxième volet, nous étudions la faisabilité et la pertinence d’intégrer cette structuration dans la chaîne d’identification. Particulièrement, nous établissons des recherches ciblées dans les catégories et nous définissons des modèles de parties à significations botaniques. Nous établissons notre évaluation sur les deux bases d’images de Scans de feuilles ImageCLEF 2011 et ImageCLEF 2012. Nous comparons notre approche par rapport à un schéma d’identification de référence, appliqué sur la totalité de la base et en utilisant l’image entière, et par rapport à plusieurs méthodes référencées dans la littérature<br>Nowadays, automatic identification of plant species, by image analysis, has become crucial to maintain, standardize or deepen knowledge about the plant community. This thesis focus on the problem of automatic identification of plant species using leaf images. It addresses two main challenges: The first challenge is the large number and the high variability in foliar morphology across species. The second challenge is the intra-species variability which occurs locally at particular regions of leaves. To overcome these two problems, a return to botany and especially to leaf botanical concepts is established in order to define an automatic structuring of leaves at two levels: The first level concerns a categorisation scheme according to the botanical concepts “arrangement” and “lobation". The second level consists in decomposing leaves into semantic parts. The approach of the thesis is based on two key parts: In the first part, we focus on establishing this botanical-based structuring process by defining simple geometric properties correlated with botanical definitions and observations. In the second part, we investigate the feasibility and opportunities to integrate this structuring process in the identification scheme. Particularly, we make targeted researches in categories and we define specific part-based models.Experiments are conducted using the ImageCLEF 2011 and 2012 Scan images leaf databases. We compare our approach with respect to the reference identification scheme, applied on the whole databaseand using the entire images, and with respect to several methods referenced in the literature

While primarily sessile, they have developed distinctive abilities to adapt to the environment. They are self-powered, self-fabricating, self-regenerating and active signal networks. They carry highly advanced systems to sense and respond to the environment. We strive for such sensing and responses in our electronics; self growing or self repairing abilities in our architecture; and being sustainable at scale in general. The industrial and technological thought process has mostly been devising artificial means or replicating natural systems synthetically. However, I propose a convergent view of technological evolution with our ecology where techno-plant hybrids are created. The approach is to formulate symbiotic associations and to place the technology in conjunction with the plant function(s). In this thesis, I go from the outside to inside the plants in conceiving such synergetic processes and present case studies of their implementation and analysis. I begin with a robot-plant hybrid where the robotic device adds mobility and is triggered with the plant's own signals. Next, lead (II) detection nanosensors are presented which reside inside the leaf of a plant and continuously sample through plant hydraulics. This is followed with a design study for plants with new conductive channels grown inside them and their subsequent use as inconspicuous motion sensors. I conclude with a symbiotic robot that lives on a sunflower plant and automatically trains or directs its growth with onboard lighting. The end result is an augmented-plant society where technology adds non-native functions or redirects the natural processes..<br>by Harpreet Sareen.<br>S.M.

Abstract:
Les molécules actuellement utilisées dans la chimiothérapie anticancéreuse sont pour la majorité d’origine végétale mais peuvent aussi provenir d’organismes marins ou de microorganismes. Ces molécules bien qu’ayant des cibles moléculaires différentes, induisent dans la majorité des cas une mort cellulaire par apoptose. Or ces dernières années le développement d’une chimiorésistance des cellules cancéreuses vis à vis de ce type de molécules s’est particulièrement accru. Face à cette situation le besoin de trouver de nouvelles molécules avec des mécanismes d’action différents se fait de plus en plus pressant. Dans cette perspective nous avons évalué le potentiel anticancéreux des alcaloïdes du Pavetta crassipes K Schum, du Kalanchoe blossfeldiana Poelln, de l’isostrychnopentamine (ISP) isolée du Strychnos usambarensis Gills et de 14 phytotoxines d’origine fongique. Nous avons évalué leurs activités inhibitrices de croissance in vitro sur des lignées humaines cancéreuses de glioblastome (U373), d’oligodendrogliome (Hs-683), de poumon non à petite cellule (A549), de prostate (PC3), de sein (MCF7), d’œsophage (OE21), de mélanome (SKMEL-28) et des lignées murines de mélanome (B16F10) et de carcinome mammaire (MXT). Ces différentes lignées sont décrites dans la littérature comme ayant des niveaux variables de sensibilité aux molécules inductrices d’apoptose. Nous montrons ainsi dans notre travail que l’isostrychnopentamine ou encore des extraits issus de Pavetta crassipes K Schum ont in vitro des activités anticancéreuses intéressantes quelque soit la sensibilité de la lignée cellulaire aux stimuli pro-apoptotiques. De surcroit les lignées connues pour avoir un certain niveau de résistance à l’apoptose sont plus sensibles (IC50 ~ 1µM) aux effets de ces deux fractions que les lignées cancéreuses ou normales habituellement sensibles à l’apoptose (IC50 ~ 2,5µM). Les taux comparatifs d’apoptose induite par l’isostrychnopentamine dans 2 lignées dites résistantes à l’apoptose (U373 et A549) montrent une complète indépendance du taux de sensibilité à l’apoptose de ces lignées. Cette situation laisse penser que l’apoptose n’est pas le mécanisme d’action principale de la molécule. L’évaluation du potentiel anticancéreux des 14 phytotoxines d’origine fongique sur des lignées cellulaires de cancer humain et murin nous a permis de retenir deux phytotoxines (le bislongiquinolide et le dihydrotricodimerol) pour des investigations plus poussées. En effet les résultats obtenus en vidéomicroscopie indiquent que ces deux phytotoxines ont un effet cytostatique qui in fine conduit à un effet cytotoxique.<br>Doctorat en Sciences biomédicales et pharmaceutiques<br>info:eu-repo/semantics/nonPublished

Le genre Delphinium L. appartient à la famille des Ranunculaceae, une des premières familles ayant divergé parmi les Eudicotylédones (clade le plus diversifié au sein des Angiospermes) et présentant une grande diversité florale.Dans un premier temps, nous avons réalisé une étude phylogénétique, morpho-anatomique et pollinique de l'espèce Delphinium turcicum (H.Duman, Vural, Aytac &amp; Adiguzel) Espinosa, espèce endémique turque connue depuis plus de 20 ans dans la nature et présentant des déviations par rapport à la fleur typique du genre Delphinium. Cette étude nous a permis de comprendre l'organisation de la fleur de cette espèce ainsi que de mettre en évidence des modifications de symétrie, du type d'organes formant le périanthe, et du développement des éperons. Des anomalies dans le développement des organes floraux, potentiellement liées à des modifications dans l'expression des gènes responsables de l'établissement de l'identité florale, sont à l'origine de ce phénotype particulier. Dans un deuxième temps, nous avons réalisé une étude de la morpho-anatomie florale de cultivars, organismes présentant des variations florales importantes issues d’une sélection artificielle, des genres Delphinium L. et Aquilegia L. (ce dernier appartenant également aux Ranunculaceae et un des genres modèles pour les études évo-dévo). Cette étude nous a permis d'identifier les étapes cruciales du développement floral pendant lesquelles ces variations prennent place. Chez les deux genres nous avons trouvé que la symétrie florale et la phyllotaxie sont conservées, tandis que l'organisation florale et la vascularisation de la fleur sont modifiées par rapport à la morphologie des fleurs typiques. La plupart des déviations morphologiques et anatomiques se situent au niveau du périanthe, et concernent notamment le nombre et l'identité des organes qui le forment. Nous avons émis l'hypothèse que les phénotypes floraux des cultivars d'Aquilegia L. et Delphinium L. résultent d'altérations génétiques affectant la taille du méristème, les frontières entre les organes d'identité différente, l'organogenèse et le développement des structures nectarifères. Dans un troisième temps, une recherche historique sur la taxonomie du genre Delphinium L. a permis de mettre en évidence les possibles ambiguïtés induites par les variations florales au sein du genre. L'inclusion de l'espèce D. turcicum dans le genre Delphinium requiert d’amender la description du genre afin d'inclure les particularités florales de l'espèce.Cete thèse permet de mettre en évidence les étapes cruciales du développement pendant lesquelles les variations morphologiques prennent place, ainsi que de viser les gènes potentiellement à l'origine de ces variations chez une espèce sauvage et chez des variétés issues d’une sélection artificielle. Ces nouvelles informations permettront d'orienter des études en évo-dévo visant la compréhension de l'évolution florale au sein des Angiospermes<br>In the evolution of seed plants, flowering plants are characterized by an especially rapid, partly due to the emergence of the floral structure. The study of teratological phenotypes is an interesting tool to better understand the origin and maintenance of floral innovations. The genus Delphinium L. belongs to the family Ranunculaceae, one of the earliest-diverging families among Eudicots and characterized by an outstanding floral.First, we carried out phylogenetic, morphological, anatomical and palynological studies of Delphinium turcicum (H.Duman, Vural, Aytac &amp; Adiguzel) Espinosa, a Turkish endemic species known for more than 20 years in the wild and presenting unusual floral features. This study allowed us to understand the organization of the flower of this species, as well as to characterize the deviations to the typical morphology (modification of symmetry, of the type of organs composing the perianth and of the spur development). Changes in floral organ development, possibly related to changes in the expression of genes involved in floral identity, are responsible for this particular phenotype. Second, I carried out a morphological-anatomical study of cultivars (organisms with major floral variations resulting from artificial selection) of the genera Delphinium L. and Aquilegia L. (the latter belongs to Ranunculaceae and has been proposed as model genus for evo-devo studies). This study allowed me to identify the crucial stages of floral development where morphological variations take place. In both genera, floral symmetry and phyllotaxis were found to be conserved, while flower arrangement and vascularization were altered with respect to the typical flower morphology. Most morphological and anatomical deviations affect the perianth, especially on the number and identity of the organs. We hypothesized that the floral phenotypes of the cultivars of Delphinium L. and Aquilegia L. result from genetic alterations affecting meristem size, boundaries between sets of organs of different identity, organogenesis and development of nectariferous structures. Third, a historical research on the taxonomy of the genus Delphinium L. highlighted the taxonomical ambiguities induced by the floral morphological variations recorded within the genus. The inclusion of the species Delphinium turcicum implies amending the genus description in order to include the floral features of the species.This thesis, through the study of a wild species and of varieties undergoing artificial selection, allowed to highlight the crucial developmental stages during which the morphological floral variations take place, as well as to target the genes possibly responsible for these variations. These results will guide future evo-devo studies aiming at understanding floral evolution within angiosperms, and better understand the evolution of angiosperms as a whole

Abstract:
The establishment of physic gardens (gardens particularly focused on plants with medicinal properties) dates back to the middle of the 16th century and generally had strong links with university medical schools (Bennett, 2014). Wyse Jackson in 1999 described botanic gardens as ‘institutions holding documented collections of living plants for the purposes of scientific research, conservation, display and education’. In 2014, Bennet described the role of botanic gardens in university education as akin to learning in Paradise. By 2050 it is predicted that almost two thirds of the world’s population will live in an urban environment. This may have a huge impact on our ability to both experience and understand the natural world. Plants have a massive impact on the earth’s environment. This paper focuses on learning beyond the classroom in botanic &amp; physic gardens and in industry settings using the annual Applied Plant Biology fieldcourse in UCC as a case study. The Applied Plant Biology residential fieldcourse has been running for the past five years (started in 2014) and takes place around Easter each year. I am the coordinator. It is a 5 day residential course for 3rd year Plant Science students. The learning outcomes of the fieldtrip state that; students should be able to discuss recent developments in industrial plant science research (facilitated in part by visits to a multinational (Syngenta) and smaller family owned companies (Tozers)); be able to explain worldwide plant conservation approaches and plant biodiversity in the context of different plant ecosystems and anthropogenic environmental impacts through engagement with such centers of excellence as Kew Botanic Gardens in London, Kew’s Millenium Seedbank Wakehurst in Sussex and the Chelsea Physic Garden in central London.

Abstract:
The University College Cork (UCC) Open Arboretum Project aims to re-imagine the original purpose of the University’s tree collection – as a teaching tool. The arboretum represents a unique on-campus learning space which has been under-utilised for teaching in recent times. The arboretum has the capacity to engage students, staff and visitors in a tangible way with important global issues (e.g. the climate emergency and biodiversity loss). It is also an opportunity to combat ‘plant blindness’, i.e. the ambivalence shown to plants in our environment compared to often charismatic animal species. Wandersee and Schussler (1999) coined the term “plant blindness” to describe the preference for animals rather than plants that they saw in their own biology students. Knapp (2019) has argued that, in fact, humans are less ‘plant blind’ and more ‘everything-but-vertebrates-blind’ with school curricula and television programming over-emphasising the role of vertebrates at the expense of other groups of organisms. Botanic gardens and arboreta have long been used for educational purposes. Sellman and Bogner (2012) have shown that learning about climate change in a botanic garden led to a significant shortterm and long-term knowledge gain for high-school students compared to students who learned in a classroom setting. There is also evidence that learning outside as part of a science curriculum results in higher levels of overall motivation in the students and a greater feeling of competency (Dettweiler et al., 2017). The trees in the UCC collection, like other urban trees also provide a range of benefits outside of the educational sphere. Large, mature trees, with well-developed crowns and large leaf surface area have the capacity to store more carbon than smaller trees. They provide shade as well as food and habitats for animal species as well providing ‘symbolic, religious and historic’ value in public common spaces. Such benefits have recently been summarised by Cavender and Donnolly (2019) and aligned with Sustainable Development Goal 11, Sustainable Cities and Communities by Turner-Skoff and Cavender (2019). A stakeholder survey has been conducted to evaluate how the tree collection is currently used and a tour of the most significant trees in the collection has been developed. The tour encourages participants to explore the benefits of plants through many lenses including recreation, medicine and commemoration. The open arboretum project brings learning beyond the classroom and acts as an entry point for learning in a variety of disciplines, not least plant science and environmental education generally.
