Winkler (1914) unites this variety with the type, but I cannot agree with him 

 in this. The flora of the geographical area where the type is growing in northern 

 Cliina and Mandshuria is rather different from that of central China. If there were 

 not such forms as Wilson's No. 2209 the branchlets and peduncles of which are 

 more glabrous, 1 should feel inclined to raise this variety to the rank of a species. 

 It represents certainly a form of higher taxonomic value than the other varieties 

 of C. cordata or the varieties of C. japonica described by Winkler. It differs dis- 

 tinctly in its densely hirsute-villose pubescence mixed with silky hairs of the 

 branchlets, young petioles and peduncles, which are sparsely hirsute or glabrous 

 in the typical C. cordata.
