A very distinct species of the Aizoon group, most nearly 
allied to 8S. aretioides, Lap. a native of the same mountains, 
though differing widely in the inflorescence and flowers, as 
a reference to the figure of that plant in this work (Tab. 
5849) shows in foliage and form, &c., of the leaves they 
are nearly identical. Indeed, in their native country, these 
Species appear to hybridize freely, as was first pointed out 
by Bentham in his Catalogue of Pyrenean plants cited 
above, where he has a var. hybrida which thus originates, 
and to which he refers as S. ambigua, DC. and S. luteo- 
purpurea, Lapeyr. (a name which Don, suspecting its hybrid 
origin, arbitrarily changed to Lapeyrousii. 
Regarding these hybrids Bentham remarks that 
they are never found except where the two parent 
species occur, when they present a suite of inter- 
mediates, amongst which it is rare to find an 
two quite alike. On the other hand, he says of S. 
SEPTEMBER Ist, 1893.
