The first record of Draba korshinskyi from Xizang was made by Hedge (Fl. Iran. 57: 181. 1968) and later confirmed by Tolmachev and Junussov (Fl. Tajik. 5: 194. 1978). The above first record from Xinjiang is based on Qinghai-Xizang Team 870482 (HNWP, KUN) and Xinjiang Team 1368 (WUK).

来自西藏的Draba korshinskyi的第一个记录被套头交易做(花期 伊朗。 57: 181. 1968) 并且过后通过Tolmachev 和Junussov 确认(花期 塔吉克族。 5 : 194 . 1978). 来自新疆的上述第一个记录基于青海西藏第870482 队(HNWP，库恩)和新疆第1368 队(WUK)。
