Wallich’s genus Dactylicapnos, referred by the authors 
of the Flora of British India to Dicentra, is here restored. 
As Prain (l.c.) has pointed out these Himalayan plants 
“ differ widely from all the North Asian and North 
American forms” [of Dicentra]. In geographical distri- 
bution, also, the two genera do not overlap, Dactylicapnos 
being essentially Himalayan (Kumaon to the Khasia Hills 
and Western and Southern Yunnan), whilst Dicentra 
occupies a more northerly area from Western Szechuan 
(Mt. Omei) through Hupeh (Cent. China) to Kamtschatka 
and the Western and Eastern States of North America 
and Canada (see map). The differences between the two 
genera, as here understood, are shown in the key on p. 105.
