Dr. Smith's Retnarks on the Sediim ochroleucum. 9 



thorp took it for our Sedum ochroleucum, on tlie authority of a 

 figure in the celebrated Imperial manuscript of Dioscoritles at 

 Vienna, which he considered as of great authority. The quali- 

 ties however recorded of tliis 3d Aei^aov are quite at variance 

 with those which Dr. Sibthorp himself attributes to the Stdum 

 ochroleucum, and which agree with those ascribed by Dioscorides 

 to his second species.
