from De Candolle's figure the inflorescence is very like that of 
5. praealium.

This is the most widely spread in gardens of the shrubby Sedums 
of the dendroideum group, and is mostly grown under that name. 
Of garden Sedums it is most likely to be confused with S. confiisum, 
a smaller plant with shorter leaves and smaller inflorescence ; the 
differences between the two are particularized on p. 211. From its 
ally, S. dendroideum, it may be distinguished by its leaves not distinctly 
stalked and lamina more oblong (not suborbicular) (see fig. 119) and 
its more branched bushy habit. 
Description. — A much-branched, glabrous, evergreen shrub, forming a low 
bush, I to 2 feet high, and equally wide. Stems roimd, smooth, green, woody
