On the taxonomy and diversity of Cruciferae in Kazakhstan

Abstract

Taxonomy and species diversity of the mustard family (Cruciferae or Brassicaceae) in Kazakhstan is updated. Draba bajtenovii described and hitherto known from Kungei Alatau is synonymized with D. fladnizensis for which it is a southern limit of distribution in the Eurasia, while Trans-Ili Alatau endemic D. microcarpella is found conspecific with a montane Asian D. lanceolata. Noccaea thlaspidioides (N. cochleariformis) is confirmed to occur in the country based on collections from Altai. Finally, Isatis trachycarpa and Smelowskia annua are shown to be absent in the flora of Kazakhstan due to the lack of gatherings confirming their occurrence in the country.
