ferum S. T. Gmelin, and the latter name, being the older, was applied 
to it by many writers. Among the names under which it is found in 
cultivation at present are altaicum, Braunii, Brownii, calabricum, 
coccineum, Comolli, hyhridum, involucratum, lividum, Middendorffianum, 
mirahile, monregalense, pallidum, oreganum, populifolium, portulacoides, 
pulchellum, pulchrum, sarmentosum, undulatum, Wallichianum. This 
list well exemplifies the appalling state of confusion that exists among 
the cultivated Sedums. There is little excuse in this case, for the plant 
varies but little, and is easily recognizable even when not in flower. 
The only variation of note is in the colour of the flowers, which, 
normally pinkish, varies from white to deep crimson (var. splendens of 
gardens) — the latter a very fine form, which is well illustrated in Kegel's 
" Gartenflora," tab. 818.

This Caucasian plant has been confused with its ally S. spurium, 
from which it is quite different. The two, which belong to a well- 
marked group almost confined to the Caucasus and Asia Minor, are 
distinct from all other cultivated Sedums in their creeping habit, broad 
leaves in opposite pairs, and pink flowers. The two are easily sepa- 
rated, and the chief diflerences between them are given under S. spurium 
on p. 194. 
Description. — A semi-evergreen, creeping, glabrous perennial, forming a 
mat. Roots fibrous. Stems creeping, red, round, striate, rather rough, with 
annular leaf scars ; branches many, ascending, the flowering shoots 6 inches 
high, the barren ones much shorter. Leaves opposite, numerous, bright green, 
loosely imbricate, rhomboid-spathulate, blunt, stalked, obscurely crenate in 
upper half, entire and tapering in lower half, margined with a narrow border of 
hyaline pimples, i inch long by ^ inch broad, pale below ; young leaves with 
fine pellucid dots ; the leaves of the barren and flowering shoots similar, the 
latter more distant. Inflorescence a lax, leafy cyme of three wide-spreading 
branches which are often forked, with flowers in the forks. Buds ovate- 
lanceolate, acute. Flowers J inch across, subsessile. Sepals linear, non- 
contiguous, blunt, green, separate nearly to the base. Petals rose, narrowly 
lanceolate, acute, edges incurved, wide-spreading, thrice the sepals. Stamens 
f the petals, filaments rose, anthers bright red. Scales small, reddish, narrower 
above, emarginate. Carpels spreading, greenish pink, slightly shorter than 
the stamens, compressed ; in fruit patent, forming, with the persistent sepals, 
a ten-rayed star. 
Flowers June- July. Hardy. 
Habitat. — Asia Minor, Caucasus, Syria, Persia. 
5. stoloniferum is rare in cultivation, though it grows very freely, 
and in my garden sows itself more than any other Sedum. I have seen 
it in the Botanic Gardens at Kew and Dresden ; it came to me from 
Wisley as 5. involucratum (an allied Caucasian plant not in cultivation).
