Annuus, foliis suboppositis petiolatis rliombeo-ovatis angulato- 

 serratis glaberrimis, racemo terminali, pedicellis demum 

 longissimis, siliculse valvis late obovatis subscabris rugosis 

 immarginatis stylo elongate pyramidato terminatis. 



Hab. Cuesto of Purruchuco, Peru. Mathews {n. 1061). 

 This singular plant is a Cremolobus in everything but the 



want of a margin to the valves of the pouch : a character, I 



think, scarcely sufficient in itself to distinguish it as a Genus. 



The Embryo has its radicle arising from the margin of the 



cotyledons, which is then applied obliquely to the back of one 



of them.
