Hab. Islands off the extreme North -West coast of America, in Behring*s Straits. Pallas, (v. Linncea, v. 

 1. p. 5j7.) — I have seen no specimens of this plant, nor have I an opportunity of consulting the figure of 

 Rudolphi, in the Transactions of the Academy of St. Petersburgh. It appears to me that this and D. tenui- 

 folia are perhaps too nearly allied to D. formosa or D. eximia.

 apice antheras tres gerentia. Gennen oblongum; stylus filiformis, germine brevior; stigma capitatum; capi-

Hab. In dark shady woods of North-West America ; plentiful near the confluence of the Columbia with 

 the sea. Scouler, Douglas.— ThU fine species of Corydalis has much affinity with C. pi^onicBfolia, Gmel. 

 Sib. t. 33, (a native of Siberia, but, according to Chamisso, extending its range to the borders of America,) 

 especially in its large woody root, in the general appearance of the flowers, and in the obliquely oval leaflets. 

 But in that species the leaves are much less compound, their alternate divisions larger, the raceme is more 

 compound, and, above all, the pedicels are greatly longer than in our plant, both iaa state of flower and fruit.
