CRUCIPERJ1. 229 



2. Card amine cordifolia, Gray, PI. Fendl. 



Hab. Near the Cascade Mountains, Washington Territory. — Our 

 solitary specimen agrees well with the plant of Fendler from the 

 mountains of New Mexico. We have it also in fruit from Fremont, 

 collected in his third expedition, on the head-waters of the Arkansas. 

 It most resembles G. rhomboidea, but differs in the leaves being all 

 cordate and petioled, in its shorter and stouter fructiferous pedicels, 

 and in the much less pointed pods. [Lyall and E. Hall have since 

 collected it in Oregon, verifying the species.] 



3. Cardamine hirsuta, Linn. 



Hab. Puget Sound, Washington Territory; the common and widely 

 diffused species. 



4. Cardamine oligosperma, Nutt, I c. 

 Hab. Puget Sound. — Evidently a distinct species, near the last. 



7. DENTARIA, Linn. 



1. Dentaria tenella, Pursh. 



Hab. Nisqually, Puget Sound. — The segments of the leaves vary 

 from oblong to broadly linear. The pod is an inch long, and more 

 than an inch wide, acuminate with the tapering style. 



8. PHCENICAULTS, Nutt. 



1. Phonic aulis cheiranthoides, Nutt. in Torr. & Gray. 



Hab. On the Upper Columbia, Washington Territory. — [Genus re- 

 duced to Cheiranthus, i. e., G. Memiesii, Benth. & Hook.]
