6. Hairy Sedum. Sedum villosum, Linn. 

 (Eng. Bot. t. 394.) 



An annual, with erect, nearly simple 

 stems, 3 to 4 inches high ; the upper 

 part of the plant always more or less 

 covered with short, viscid hairs, like the 

 thick-leaved S. Leaves more than twice, 

 often 4 or 5 times, as long as thick, al- 

 ternate or scattered. Mowers few, of a 

 pale, rather dingy rose-colour, in a small, 

 rather loose, terminal cyme. Sepals 

 ovate and green. Petals ovate, about 

 twice as long as the calyx. 



In bogs and along stony rills, in the 

 mountains of western, central, and north- 

 ern Europe, frequent in northern Eng- 

 land and the Scotch Highlands, but not 

 recorded from Ireland. Fl. summer.

7. Biting Sedum. Sedum acre, Linn. (Fig. 364.) 

 (Eng. Bot. t. 839. Wall-Pepper.) 



Tufts perennial and procumbent, con- 

 sisting of numerous short barren stems, 

 and erect or ascending flowering 

 branches, from 1 to 2 or 3 inches high ; 

 the whole plant quite glabrous, assu- 

 ming a yellowish tinge, and biting to the 

 taste when chewed. Leaves small, thick, 

 ovoid or sometimes nearly globular, 

 those of the barren shoots usually closely 

 imbricated in six rows. Elowers of a 

 bright yellow, in small terminal cymes. Sepals very short. Petals 

 much longer, narrow-oblong and pointed. 



On walls and rocks, in stony and sandy places, throughout Europe and 

 Russian Asia, from the Mediterranean to the Arctic regions. Abun- 

 dant in Britain. Fl. summer.
