5. CRDCIFERiE. 
or quite smooth rather dark full green leafy. St. stiffly erect 
not much branched often violet or purple towards the base. L. 
stalked 4 or 5 in. long. FI. y. very small and inconspicuous, the 
pet. scarcely longer than the sep. Pods shortly stalked an inch 
or more long attenuated upwards neither compressed nor angular 
but round and striated, the valves being distinctly 3-nerved. 
Seeds minute cylindric-oblong finely reticulato-punctate. — In 
habit as in characters allied to S. officinale. The identity of 
Desfontaines’ pi. cannot be questioned, although he describes 
(probably from dried specimens) the fi. as being white : whence 
also doubtless its wrong reference by De Candolle to the fol- 
lowing section. Sisymbrium nitidum Zea and S. rigidulum Lag. 
are also, according to Webb, precisely the same pi.

a small flat rose-like tuft of a few 1., loosely branched, often 
simple, almost filiform, slightly hairy below, smooth upwards. 
Boot-leaves scarcely i in. long attenuated downwards into a 
stalk pilose, their hairs forked and simple ; st.-l. few linear-lan-

Fl. small white. Pedic. longer than the cal. Pet. obtuse about 
twice as long as the erect sep. Stain, about as long as the pet. 
Pods scarcely an inch long and £ of a line wide, not much 
longer than their pedic. very fine and slender subquadrangular, 
the valves having a prominent dorsal nerve, but the lateral 
nerves faint and obscure. Seeds bright tawny y. oval not 
striated.
