corpore recto vel paullo patenti, corpore oblongo tergo valde 

 carinato minime rhomboideo sub rostro abrupte coarctato later-

 by the stout, conspicuously clavate scapes, curved fruiting re- 

 ceptacles and small, narrow achenes.

This species is a near relative of C. occidentalis (Wats.) How., 

 but is readily distinguished by the remarkably long and loose 

 fruiting racemes, the larger flowers and the long beak of the 

 siliques.
