Abstract (sommario):

In a screening of 43 accessions of predominantly Australian sundew species (Drosera), naphthoquinones were detected convincingly for the first time in D. section Lasiocephala (D. petiolaris group, or ‘wooly sundews’), where these metabolites remain restricted to a minority of four closely related species. Great chemical similarity across the large geographic range confirms a close phylogenetic affinity between taxa of the D. peltata species group (of D. section Ergaleium, from tropical and Eastern Asia to New Zealand). Drosera barrettiorum (D. section Arachnopus) is chemically confirmed as a c

Abstract (sommario):

The Cape Sundew (Drosera capensis L) is one of best known and most widely grown of all the sundews. Yet it remains poorly known in the wild. I present a summary of my observations of Drosera capensis in nature, from the study of herbarium specimens and the literature, and cultivated plants to present a current picture of its variation in cultivation and in the wild.

Abstract (sommario):

The acetogenic naphthoquinones, plumbagin (P in this paper) and ramentaceone (= 7-methyl- juglone, M in this paper), are important chemotaxonomic markers in sundews (Drosera L.) (D rand & Zenk 1974; Culham & Gornall 1994; Schlauer & Fleischmann 2016; Schlauer et al. 2017; 2018). Most of the previous phytochemical data relate to the chemotaxonomy of the genus in Australia, where several endemic lineages have evolved into the bulk of the species diversity. In this study several taxa presumed to occupy crucial branching points in the phylogenetic backbone of the genus (Rivadavia et al

Abstract (sommario):

The thread-leaf sundews of the Eastern North America are spectacular plants with erect, tall, filiform leaves. Backlit in the morning or evening light, their leaves burst with sunlight. There are two thread-leaf sundews (also known as dew-threads), known as either infraspecific taxa within Drosera filiformis, or as Drosera filiformis and Drosera tracyi. In this paper, I review their history of discovery, the details of their ranges, and the arguments regarding whether the two taxa should be treated as one species or two. I also describe the morphological differences between the two sundews. In

Abstract (sommario):

A detailed study of 44 accessions representing 38 taxa (76% of the diversity known at present) of pygmy sundews (Drosera sect. Bryastrum) reveals the first naphthoquinone patterns in this lineage, in which previous studies have not yielded reliable evidence for naphthoquinones. While most samples do not display detectable amounts of naphthoquinones as previously reported for the group, ramentaceone is detected in three mutually related taxa, and both ramentaceone and its regio-isomer plumbagin is present in all accessions investigated of D. pulchella.

Abstract (sommario):

The pygmy sundews (Drosera section Bryastrum) are the second-largest group of Australian Drosera in terms of species number following the tuberous sundews. According to the latest revisions (Fleischmann et al. 2018; Robinson et al. 2018) they currently comprise 51 species in southwest Western Australia and six named natural hybrids (Lowrie 2014; Lowrie et al. 2017). Within the pygmy Drosera, a wide range of flower colors can be found, ranging from pure white, various shades of pink, metallic orange, and red to yellow colors, quite often with bi- or rarely even tricolored petals (Lowrie 1989; R

Abstract (sommario):

Drosera pygmaea DC. grows naturally across wetter parts of southern Australia and also occurs in New Zealand, making it the most widespread of all pygmy sundews. It is aptly named thanks to its small size which makes it easy to overlook and challenging to study. However the effort to study this species has revealed some interesting morphological variation which is discussed here.

Abstract (sommario):

The genus Drosera (sundews) is represented in British Columbia (BC), Canada, by Drosera rotundifolia (L.), Drosera anglica (Huds.), and their hybrid Drosera × obovata (Mert. & W.D.J. Koch). All three can be found in Sphagnum bogs of central BC, including those within the Aleza Lake Research Forest (ALRF) located 60 km east of Prince George. Vegetation patterns in bogs are known to be correlated with light, water, and nutrient gradients, and despite information being available on the influence of light and water on Drosera occurrence, little information is known about the role of nutrients.

Erect-growing tuberous sundews of Drosera subgenus Ergaleium section Ergaleium produce seeds of diverse size and shape. Seeds produced by such species as D. andersoniana, D. macrantha, and D. pallida are large and winged, and fit the classic model of those dispersed by the wind. However, many species in this section produce small, round seeds (e.g. D. gigantea, D. salina, and D. yilgarnensis) that appear better suited to dispersal by gravity or water than by the wind. I propose here, that long-distance dispersal of these species may also be facilitated by the transport of detached plant parts,

Abstract (sommario):

Species of the genus Drosera, known for carnivorous plants, such as sundew, have been traditionally used for centuries as medicinal plants. Efficacy-determining compounds are naphthoquinones and flavonoids. Flavonoids possess a broad spectrum of bioactive properties, including biofilm inhibitory activity. Biofilms render antibiotics ineffective, contributing to the current rise in antimicrobial resistance. In this study, the biofilm inhibitory activity of two European sundew species (Drosera rotundifolia and Drosera intermedia) grown agriculturally in Germany and four commercial sundew product

Abstract (sommario):

Drosera rotundifolia L. is a carnivorous plant used in traditional medicine for its therapeutic properties. Because of its small size, its collection in nature is laborious and different cultivation methods have been studied to ensure availability. However, only a few studies exist where the lab-grown sundew tissue and field-grown sundew would have been compared in their functionality or metabolic profiles. In this study, the antioxidant and antiviral activities of lab-grown and field-grown sundew extracts and their metabolic profiles are examined. The effect of drying methods on the chromatog

Abstract (sommario):

Bioadhesives have drawn increasing interest in recent years, owing to their eco-friendly, biocompatible and biodegradable nature. As a typical bioadhesive, sticky exudate observed on the stalked glands of sundew plants aids in the capture of insects and this viscoelastic adhesive has triggered extensive interests in revealing the implied adhesion mechanisms. Despite the significant progress that has been made, the structural traits of the sundew adhesive, especially the morphological characteristics in nanoscale, which may give rise to the viscous and elastic properties of this mucilage, remai
