Kansu: Monastery Dshoni, between Morping and Wuping, and in the 

 valley of the Tao ho near Dsio tsheng, G. N. Potanin, 1885 (ex Maximo- 

 wiez, 1. c). 



Among the numerous specimens of C. montana in this herbarium I have 

 found only one which agrees in its leaves with var. pentaphylla and this 

 is Forrest's no. 10222 from Yunnan which according to its large rosy pink 

 flow r ers is referable to var. rubens Wils. 



Clematis acerifolia Maximowiez in Bull. Soc. Nat. Moscou, liv. 2 (Fl.

 & Gagnepain in Bull. Soc. Bot. France, l. 524 (1903); Contrib. Fl. As. Or. 

 1. 9 (1905).— Limpricht, Bot. Reis. Hochgeb. Chin. Ost-Tib. 376 (1922).

 867 and 872 (ex Pritzel, 1. c). 



Kansu: between Morping and Wuping, on Itohu-shan, G. A 7 . Potanin, 



1885 (ex Maximowiez, 1. c). 



Distribution: also Szechuan. 



Finet and Gagnepain consider this species of which I have seen no 

 specimens a variety of C. montana, but the description by Maximowiez 

 of the peduncles as bracteated in the middle and 1-3-flowered and of the 

 flower as having 6 sepals does not agree with C. montana; possibly Maxim- 

 owicz's species belongs to C. Fargesii Franchet, while the specimens froan 

 Batang cited by Finet & Gagnepain may represent C. montana var. 

 pentaphylla Maxim.
