Lieutenant-Colonel Prain, when discussing (Joan^. As. Soc. Beng. lkv. 
p. 28) the relationships between Corydalis Coiimirickwi and C, points out 
that neither of these is in the least degree variable, at all events in the direction of 
passing into each other. “ An apparent exception to this is a solitary gathering from 
Chumbi which with flowers exceedingly like those of C. Casimiriana has unripo 
capsules like those of C. longipes. But the evidence that we have in this plant an 
intermediate between C, Casimiriana and C. longipes is far from complete. It 
flowers instead of being intermediate in form between those of the other two have n 
gpur with an exaggerated curvature. The stigma too differs from that in either C. 
Casimiriana or C. longipes and resembles that of C. tongolensis Franchet from 
Szechuen, another nearly related but nevertheless quite distinct species.’.' The plant is 
referred in the Calcutta Herbarium to C, longipes DC. var. ckumbica but in a npte 
on the cover Colonel Prain states that it is probably a distinct species. Without a 
careful study of this and its close allies 1 hesitate to do more than append the fqsUowing 
field notes : —

petioled, almost tritemate ; apices and sinuses of segments marked with a black dot 
Racemes simple elongate. Bracts^ lower similar to the leaves, gradually becoming 
simpler until only trfid leaves. Flowers distant. Sepals two, fimbriate whitish scale
