This plant is unquestivnably the S. dongifolium of Pursh,

lenberg’s Catalogue, as I have examined a specimen 
which he had so named. 
Of. this genus there are 9 genuine species in Europe 
(1 in Greece with yellow flowers); 7 at the Cape of Good 
Hope; 2 in Japan, and 1 in China, 1 or 2 in North Africa. 
Few of them probably accord with the European and 
North American part of the genus. —
