180 TETRADYNAMIA— SILICULOSA. Iberis. 



leafy, smooth like every other part. Leot'ei somewhat glaucous, 

 deeply pinnatifid; their fore sides mostly subdivided in a similar 

 manner. Fl. opposite to the leaves, white, small, densely co- 

 rymbose. Pouches in dense clusters, much shorter than the 

 leaves, kidney-shaped, elegantly notched and furrowed, but with 

 no terminal cleft. iS/?//e prominent, though short, thick and 

 pyramidal. Each cell is thick and leathery, never splitting into 

 valves, and contains one ovate seed, whose cotyledons are rather 

 oblong and channelled than linear. 

 The whole plant is nauseously acrid and fetid, and must require 

 much boiling to render it eatable.

Annual. July. 



Root fibrous, small. Stems procumbent, a foot or more in length, 

 branched, leafy, finely hairy. Leaves smooth, flat, deeply pin- 

 natifid, their lobes cut in a similar manner, especially at the 

 fore side. Clusters generally opposite to the leaves, and often 

 exceeding them in length, slender, of numerous, small, white 

 /lowers, having only 2 or 4 stamens, scarcely ever more. Pouch 

 of 2 very distinct, round, turgid, wrinkled lobes, with the stigmas 

 almost sessile, in the deep cleft between them. 



The original specific name, given by Linnaeus, and so very appro- 

 priate, appears preferable to pinnatifida, which does not distin- 

 guish the present species from the foregoing.
