A pretty little Sedum, not closely resembling any other species in 

 cultivation. Partly on account of the way the little, thick obovate 

 leaves readily drop off and root, a close tuft of tiny bright-green 

 rosettes is formed around the fleshy rootstock, from among which leafy 

 fiower-stems rise, often decumbent under their own weight, bearing 

 small white, rather bell-shaped, flowers, the lower part of the petals 

 being erect, the upper part spreading, broad, apiculate, hiding the 

 blunt oblong sepals. The carpels are purple on the inner face. 



Description. — A small glabrous evergreen perennial. Rootstock fleshy, 

 large, decked during winter with many minute leaf -rosettes, some of which 

 elongate in summer into smooth, round, leafy flowering stems, erect (at least at 

 first), 3-4 inches high (in cultivated plants ; 8-20 inches according to Rose), 

 simple or branched. Leaves alternate, crowded, sessile, extremely fleshy, flat 

 above, very convex beneath, obovate to rhomboidal, tapering at base, rounded 

 or bluntly pointed at apex, minutely papillose especially when young, bright 

 green, becoming smaller, narrower, and dotted with red above, about f inch 

 long by I inch broad at base of flowering stem, half that size on barren shoots 

 and at top of flowering stem. Inflorescence terminal, compact, flattish, of 2 or 

 3 usually simple branches, an inch across. Buds oblong-ovate, the corolla 

 almost hidden by the long erect sepals. Flowers almost sessile, | inch across.
