the upper lying against the radicle, which is on the back of one 
of them. Pod short and broad, more or less compressed parallel

GENUS XVII—CAMELINA. Crantz. 
Sepals short, erect, nearly equal at the base. Petals equal,

Pods obovate or turbinate, slightly compressed parallel to the 
replum. Valves with a dorsal nerve, and very convex in the 
middle, depressed round the margins, abruptly terminated by a 
linear-acute point, which is applied to the base of the long per-
