Inflorescence terminal, cymose-paniculate, large, about 2 to 6 inches long by 4 inches across. Flowers bright yellow, nearly i inch across. Sepals ovate, obtuse.

Amer., ; 1, 398. " N. Amer. Flora," 22, 70. 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. confusum, 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 round, smooth, green, woody VOL. XLVI. P. Please note that these
