Abstract:
A checklist of the economically and ecologically important subfamily Maloideae (Rosaceae) is presented. One thousand one hundred and ten species are recognised in 23 genera, as well as 33 species in 13 intergeneric hybrid genera. An alphabetic arrangement is used within each taxonomic rank. The larger genera are subdivided into infrageneric groupings to represent structure. Several new infrageneric taxa were created to reconcile different sources. This checklist is believed to be complete to 1986 and represents the compilation and synthesis of over 170 publications. The following new names are

Abstract:
The Rosaceae family plays a leading role in the dendroflora of Armenia. The Pyrus, Sorbus, Crataegus, Cotoneaster, Rubus and Rosa genera representing the family are of great importance in Armenia in the formation of various plant coexistences. With its species composition and taxonomic diversity, Crataegus is one of the largest genera in the Rosaceae family. Growing in Armenia in low, medium and high mountain zones, Crataegus has a great role in the formation of dendroflora: they are an important element of a number of forest coexistences, form a sub-forest with other representatives of dendro

This article examines the environmental problems of the cities of Kazakhstan, using the example of the Almaty metropolis, where, with the development of the urbanization process, the natural environment in cities is changing very much, which is characterized by a specific ecological environment with a special type of circulation of substances and energy, not typical of natural communities. The importance of green spaces in urbanized areas is very difficult to overestimate. Green plants play a major role in protecting the population of large cities from dust, smoke and harmful gases.

Abstract:
Crataegus sp. is a tree that grows in temperate zones with worldwide distribution and is commonly known in Mexico as tejocote. The use of products derived from Crataegus in traditional medicine, food, and cosmetics has increased over the last few years and the relevance of this plant has also grown. Here, we report a disease that was observed in tejocote plants that grew both in the wild and in greenhouses in Puebla (Mexico). The disease was characterized by necrotic spots on the leaf ranging from brown to reddish tones that were accompanied by structures on the back of the leaf. Furthermore,

This review is the first to consider, all together, the pharmaceutical, phytochemical, functional and therapeutic properties of C. monogyna based on numerous valuable secondary metabolites, including flavonoids, vitamin C, glycoside, anthocyanin, saponin, tannin and antioxidants. Previous reviews dealt with the properties of all species of the entire genera. We highlight the multi-therapeutic role that C. monogyna extracts could have in the treatmen

Abstract The Crataegus and Rosa genera are critical taxa. Because of difficulties in species identification, nobody has dealt with the distribution of these genera in the Solec Basin (Niecka Solecka) and southern part of the PiOczUw Hummock (Garb PiOczowski) thus far. The aim of this work was prepare a complete list of critical species of these genera in the study area. The floristic studies were carried out in the years 2004-2009. Nineteen species were recorded: 6 hawthorns and 13 roses. Seven species were new for the flora of the studied area (4 roses and 3 hawthorns).

Abstract:
In Poland, the bird’s-eye primrose (P. farinosa) is a rare and critically endangered species. Currently, it occurs only in one location in the area of the Jaworki village in Radziejowa Range (of Beskid Sądecki mountains). This is the last of the nine previously existing locations, and the only one occurring in the mountains. To maintain the species, as well as the moutain fen on which it grows, a multiannual conservation program has been implemented, including, among other measures, conducting environmental monitoring and performing active protection procedures.

Одной из главных задач, стоящих перед ботаническими садами, является внедрение новых видов, форм и сортов растений в городское озеленение, в широкую практику урбанофлористики. Красивоцветущие древесные и кустарниковые виды растений всегда являются важным акцентом в парках и украшением улиц и скверов. Анализ каталогов ботанических садов, в которых показаны удачные опыты по интродукции новых видов для конкретного региона страны, позволяет значительно расширить и обогатить ассортимент новыми красивоцветущими кустарниками и древесными деревьями.
