basi dilatata insigniter sagittato-appendiculato, auriculis subulatis ; 

 racemo brevi laxo ; petalis albis (lin. 3 longis) calyce plus duplo 

 longioribus ; siliqua angusto-lineari compressa in stylum sat longum 

 attenuata ; stigmate parvo. — Wet ground along streamlets in the 

 higher Iron or Smoky Mountains of North Carolina and Tennessee, 

 collected in 1844 by Rugel, and about the same time by Buckley; 

 common in the higher wooded parts of Roan Mountain, where it was 

 collected in June, 1879, by Messrs. Canby, Redfield, Sargent, and 

 myself. A specimen from Buckley was by me confounded with C. 

 rotund! folia, and is the only authority we know of for attributing to 

 that species occasionally trisected leaves, as is done in the Manual of 

 the Botany of the Northern States. An imperfect original specimen 

 from Shuttleworth was mixed up with a Florida species, intermediate 

 between Cardamine and Nasturtium, first received from Leavenworth 

 without fruit, and referred in the Supplement to the first volume of 

 Torrey & Gray's Flora to N officinale ; it was afterwards received 

 from Buckley, then from Shuttleworth (coll. Rngel), first as Carda- 

 mine curvisiliqua, Shuttl., and again as Nasturtium stylositm, Shuttl. 

 Lately it has been sent by Dr. Garber.

 renni, minute pubescens ; stipulis parvulis liberis scariosis ; foliolis 10-

 lis. — " Interior of Oregon," coll. Douglas, in fruit. Mentioned in 

 Torr. & Gray, Fl. i. Gl>4, and in Proc. Am. Acad. vi. p. 234. Now 

 collected in Grand Round Valley and Blue Mountains in the eastern 

 part of Oregon, in April, 1878, in flower and with forming fruit, 

 by William C. Cusick ; and, about the same time, in Klikitat Val- 

 ley, Washington Territory, by Joseph Howell. No other of the 

 thick-walled Phacce much resembles this now completely identified 

 species.
