PRAEGER—SOME ASIATIC SEDUMS. 71 
it has the characteristic short deltoid sepals of indicum, not the 
oblong sepals at least equalling the petals of ambiguum. I grew 
for some years indicum and its vars. yunnanense and denstrosu- 
latum, and the flowers displayed no marked variation in respect 
to their sepals, and they were uniformly biennial, torming a 
Sempervivum-like rosette in the first vear and a centrai flowering 
stem in the second.

statura minore, staminibus brevioribus vix adnatis, squamis 
semi-ellipticis integris (nec subquadratis emarginatis) distincta. 
S. gelidum, Ledeb. foliis oblongis plerumque dentatis, stamini-
