400 34. CRASSULACE^. 



New Guide, Mr. Lees reports it as " a genuine product of 

 Natiu-e on the Malvern rocks, at about 800 feet." And 

 several botanists have recorded it from the neighbourhood 

 of Bath or Bristol, in terms which may lead to the belief 

 of its being native there also. The counties of Pembroke and 

 Westmoreland require to be confirmed on better and more 

 recent authority ; especially as S. anglicum is occasionally 

 mistaken for S. album. The question of nativity appears 

 almost to be limited to this, for the present, ' Is Sedum 

 album a native upon the Malvern rocks ?' Mr. Babington 

 mentions S. turgidum in his Manual of British Botany, 

 but indicates no locality for it ; and the plant is unknown 

 to me as anything distinct fi-om S. album.

 w Native. Glareal and Rupestral. The- Rev. Mr. Ruther- 

 ford sends this species from -Kingussie, in Moray, to the 

 Botanical Society of London. On account of that locality 

 the altitude of 250 yards is indicated for the plant ; though 

 I have not myself seen it so high, northward of the Forth. 

 If truly native there, it is probable that the temperature 

 might be correctly reduced to at least one degree lower ;
