Notes:—Two specimens Wang (2018) cited under Thalictrum sparsiflorum , Beijing Chin. Trad. Med. Exped. 417 (PE01197733) from Mentougou district in Beijing city and Miyun Exped. 502 (PE01204172) from Xinglong county in Hebei province ( Fig. 14 ), actually belong to T. przewalskii . Thalictrum sparsiflorum is similar to T. przewalskii in habit and having 3‒4-ternate leaves, narrowly clavate filaments, stipitate carpels and compressed achenes, but differs by having few-flowered and leafy inflorescences, apically reflexed pedicels, and shorter stipes of carpels and of achenes ( Figs. 15 , 16 ; Maximowicz 1877, Wang & Wang 1979, Fu & Zhu 2001). It is widely distributed in northeastern Asia and North America, but in China, it occurs only in eastern Heilongjiang and eastern Jilin provinces (Anonymous 1975, Wang & Wang 1979). The two specimens just mentioned above should be referred to T. przewalskii , not T. sparsiflorum , by having many-flowered, not leafy inflorescences, erect, not apically reflexed pedicels, and long stipitate carpels and achenes ( Fig. 14 ). Our survey of Thalictrum specimens in the major Chinese herbaria, including CDBI, HNWP, IBSC, IFP, KUN, NAS, PE, SZ, and WUK, also indicates that in China T. sparsiflorum occurs only in Heilongjiang and Jilin, not in Beijing and Hebei as stated by Wang (2018).
