ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 41 
Flowers June. Hardy. 
Habitat. — Himalayan region ; Yunnan. 
This species has been in cultivation for some years, as at Kew, 
Edinburgh, Glasnevin, and Bees nursery at Chester, but it seems 
to be not a good doer in cultivation (though a very robust plant in 
Fig. II. — S. rotundatum. Male flower, x 5. 
the wild state), and it was only when this paper was at press that I 
at last saw flowers (at Edinburgh). The plants in cultivation were 
derived from seed collected by F. Kingdon Ward (No. 764), G. Cave 
(No. 1456), and G. Forrest (no number). 
Named from its round leaves.

A peculiar Rhodiola, which in its tall growth and broad leaves 
recalls 5. Telephium and its aUies ; but it is at once distinguished 
from these by its characteristic Rhodiola rhizome, its stems produced 
from the axils of broad scales, its globular buds, and its dioecious 
black-purple flowers with very conspicuous scales forming a cup 
round the carpels. Its broad leaves and large scales will identify 
it from among the other Rhodiolas found in cultivation. 
Description. — A glabrous herbaceous perennial. Rootstock very fleshy, 
branched, growing points furnished with scales. Stems annual, arising from 
the axils of the older scales, erect, simple, leafy, round, smooth, i-i| foot high. 
Leaves alternate, sessile or very shortly stalked, obovate or elliptic, about 2 inches 
long by I to I inch broad, often largest near the top of the stem, becoming minute at 
the base, more or less toothed, very smooth, green with a pale midrib, pale below. 
Inflorescence terminal, large, loose, leafy, its branches rather long, slightly 
pubescent. Buds globular, purple mottled with green. Flowers dark reddish- 
purple, nearly f inch across, on slender pedicels longer than the flowers. Male 
FLOWER : — sepals narrow, tapering, rather acute, purple ; petals obovate-oblong, 
blunt, spoon-shaped at apex, dark purple, wide-spreading, i\ times the sepals ; 
stamens purple, slightly shorter than the petals ; scales very broad, contiguous, 
emarginate, forming a deep purple shining cup round the carpels ; carpels short, 
lightly exceeding the scales, erect, dull purple.
