A checklist of Onagraceae in the Pan-Himalaya region Author Luo, Yike Author Xie, Lei text Phytotaxa 2023 2023-05-17 597 4 245 268 http://dx.doi.org/10.11646/phytotaxa.597.4.1 journal article 10.11646/phytotaxa.597.4.1 1179-3163 7958600 2.1c. Circaea alpina L. subsp. micrantha ( Skvortsov 1977: 36 ) Boufford (1982: 959) . ≡ Circaea micrantha A.K.Skvortsov. Type :— CHINA . Gansu : at the temple of Tcheibsen-hit, 2743 m , 1901, V. Ladygin 514 ( LE ) . Distribution: — U Yarlung Zangbo, M Yarlung Zangbo, L Yarlung Zangbo, C Nepal , E Nepal , W Nepal , Tangut, S Hengduan, N Hengduan. Note: —This subspecies can be recognized by its translucent leaves with cordate leaf bases. Individuals of this subspecies sometimes also have purple pigment on their fruit hairs ( Boufford 1982 ). Although Skvortsov (1977) stated in the protologue that the type is stored in LE , the type status is still dubious because we cannot guarantee the existence of duplicates. So, we leave this issue open for further studies.
