12 D. Prain — Some additional Fumariaeeae. [No. 1, 



In habit, the Himalayan Dicentras differ widely from all the North Asian and 

 North American forms ; in this respect they agree with the American plant known 

 as Adlumia cirrhosa, which, differing as it does from Dicentra only in having its 4 

 petals united, scarcely deserves generic rank.

This is the second of the scandent group of Dicentras characteristic of the 

 Himalayan region that extends to South-west China. M. Franchet in referring 

 the whole genus Dicentra to Corydalis adopts a course with which the writer 13 

 much inclined to agree, but which in a paper like the present it is not advisable to 

 follow. The step is only a reversion to the view advocated by Sprengel. By a 

 lapsus calami the specific name of another North-west Himalayan plant has been 

 given in the Plantae Delavayattae ; Delavay's specimens show that the Yunnan plant 

 is D. Roylei.

Nepal is also given as a locality for this species both in Flor. Lid. and Flor. Brit. 

 Ind. This is the result of Dr. Wallich having, in the distribution of the E. T. C. Her- 

 barium, mixed specimens of this species sent him by Blinkworth, with his own 

 Dactylica/pnos thalictrifolia from Nepal. But though Wallich erred in his identifi- 

 cation he did not issue Blinkworth's plant as a Nepalese one, the original tickets 

 as well as the lithographed catalogue alike indicate carefully that Blinkworth's 

 plant (which is Wallich's n. 1426/2) came from Kamaon. Wallich's n. 1426/1, which 

 he himself collected in Nepal, is not a mixture of two species ; it is his own Dacty- 

 licapnos thalictrifolia and is the only Dicentra that he obtained in Nepal. The 

 Wallichian error was pointed out by Royle (III. 68) in 1839, but his remarks were 

 unfortunately ignored by Walpers (Bepert. i. 118) when in 1S42 he revised the
