A new species of Astragalus (Fabaceae) from west coast of Baikal Lake (Irkutsk Oblast)
Abstract
A new species, Astragalus rytyensis Stepantsova (Fabaceae), growing on the west coast of the lake Baikal, is described. Morphological differences from related taxa – A. versicolor Pall., A. austrosibiricus Schischk., and A. inopinatus Boriss., are discussed and uncertain position of the new species in the system of the genus is emphasized which is intermediate between subg. Phaca (L.) Bunge sect. Hemiphaca Bunge and subg. Cercidothrix Bunge sect. Onobrychium Bunge. Ecological and phonological features of A. rytyensis are reported and chromosome numbers of the new (2n = 6x = 48) and related species are counted.Downloads
