large as in the pinnatifid forms, namely, about 2 lines long, which is 

 larger than those of the foregoing species. The racemes are either 

 rather short and few-flowered, or elongated in fruit. The mature 

 silicles are from 2 to 3 lines broad ; the valves considerably longer than 

 the stipe, surrounded with a pretty wide wing, which is either repand 

 or almost entire, or sometimes with the margin sinuate-toothed; the 

 disk smooth or slightly rugose. Style nearly as in the foregoing, or 

 perhaps not quite so long, subulate or tapering upwards from a very 

 thick base. 



The specimens of Matthews, figured by Hooker, do not exhibit any 

 mature fruit. I add a ripe silicle, therefore, to Plate 3. The wing- 

 varies considerably in different states or stages of the plant ; but I 

 think it unlikely to pass into the foregoing species. Forms of the 

 species gathered by Professor Jameson and Mr. McLean are also pre- 

 served in the Hookerian herbarium.

A dwarf, cozspitose, and multkipital plant, with the aspect of an 

 alpine Draba, except as to the pods. Leaves all radical and rosulate- 

 tufted, or sometimes with a small one on the scape, rather thick and 

 fleshy, spatulate-linear, 3 to 5 lines long, sparsely hispid all over, or
