Chesneya dshungarica Goloskokov (Bot. Mater. Gerb. Bot. Inst. Komarova Akad. Nauk S.S.S.R. 18: 117. 1957) was recorded from Xinjiang by Chang Y. Yang (Claves Pl. Xinjiang. 3: 72. 1985). However, the present authors found no relevant specimens and therefore could not substantiate the occurrence of this species in China.
About 21 species: C and SW Asia, Mediterranean region; seven species (two endemic) in China.
