at Glasnevin ; the description made from these small plants has been 
supplemented therefore by notes from the description in " North 
American Flora." Some further information is contained in Prof. 
Cockerell's note [loc. cit.). 
The name is in honour of T. D. A. Cockerell, the first collector of 
the plant.

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 
flower-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 \ 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, tlie corolla 
almost hidden by the long erect sepals. Flowers almost sessile, | inch across.
