In hilly pastures, cultivated and waste places, over the greater part 

 of Europe, from Sweden to the Caucasus. Generally distributed over 

 England, Ireland, and southern Scotland. Fl. summer. 



2. Smith's Cress. Lepidium Smithii, Hook. (Fig. 102.) 

 [Thlaspi hirtum, Eng. Bot. t. 1803.) 



Yery near the field C, but forms a 

 more or less perennial stock. The stems 

 are several together, much shorter, and 

 decumbent at the base ; the foliage more 

 hairy, the flowers not quite so small, and 

 the pod glabrous. 



In hilly pastures, cultivated and waste 

 places in western Europe, from Spain 

 and Portugal, up western France to 

 England, Ireland, and southern Scot- 

 land. Fl. spring and autumn. It should, 

 perhaps, be united as a mere variety 

 with the L. hirtum from south-western 

 Europe, which is hairy all over, includ- 

 ing the pods, and the L. heterojphyllum 

 from western Europe, which is glabrous 

 all over. 



3. Hoary Cress. Lepidium Draba, Linn. (Eig. 103.) 



(Eng. Bot. Suppl. t. 2683.) 



A perennial about a foot high, more 

 or less hoary with a minute down. The 

 stems stout and erect, branching in the 

 upper part. Leaves oblong or broadly 

 lanceolate, usually slightly toothed, \\ 

 to 2 inches long, the lower ones stalked, 

 the upper ones clasping the stem with 

 projecting auricles. Hacemes not much 

 lengthened, forming a broad flat corymb. 

 Pods about 2 lines broad and not quite 

 so long, very thick, the valves sharply 

 keeled but not winged, the style promi- 

 nent. 



In waste places, by roadsides, etc. ; 

 common in central and southern Europe,
