Чекліст флори України. 4: родина Rosaceae (Rosales, Angiosperms)

Abstract

According to current estimates, the family Rosaceae includes from 90 to 120 genera and 3000-3500 species, distributed mainly in temperate and subtropical regions of the earth; much lessin the tropics and desert regions. In Ukraine -59 genera and over 280 species (along with subspecies), along with cultivated, which are often wild (in total in the culture and botanical gardens are grown about 360 species that do not go beyond cultivation). Compared with the previous edition of the checklist, there have been significant nomenclature changes in the genera Alchemilla, Crataegus, Potentilla, Rosa, Rubus, Sorbus and others. In particular, independent genera, isolated from the genus Potentilla s. l. are considered Argentina, Comarum, Dasiphora, Drymocallis, Sibbaldianthe. Some genera isolated from Sorbus s. l. are: Aria, Cormus, Hedlundia, Karpatiosorbus, Torminalis, which is confirmed by literature data based on studies of the nucleotide sequences of nuclear and ribosomal DNA. Microcerasus, Padellus, isolated from Cerasus s. str. (Prunus s. l.). At the same time, the genera Aphanes, Duchesnea are included in the genus Potentilla; Mespilusin the genus Crataegus; Poteriumin the genus Sanguisorba. Many new species (as well as those translated into synonyms) appeared in the genera Alchemilla, Crataegus, Potentilla, Rosa, Rubus. The annotated list also includes cultivated species, including those that do not escape beyond culture. The genera Alchemilla (64 species), Rubus (63), Crataegus (37), Potentilla (37), Rosa (53), are the most numerous in the flora of Ukraine (together with the most widely cultivated species that often go wild). At the same time, many genera are represented by one or two species (Aremonia,
