ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 51 
Flowers June-July. Hardy. 
Habitat. — Himalayan region. 
Very rare in cultivation. Received from Lissadell Nursery 
(where it was raised from Darjeeling seed labelled 5, fastigiatum) ; 
also from Edinburgh Botanic Garden unnamed, collected by Captain 
Bailey on the Upper Brahmaputra. The former plants were male, 
the latter female. The male flowers were imperfect, and are not 
described here.

In nature a smaller plant than any other Rhodiola in cultivation, 
with a caudex densely clothed with the fine wiry black stems of former 
years. In cultivation larger, but still smaller than any of the other 
species, with linear acute leaves about J inch long and small few 4- 
parted flowers. The only specimens seen in cultivation were house- 
grown and still young, so only a brief description is given, helped out 
by Hooker's " Flora of British India." 
Description. — A usually glabrous herbaceous perennial. Rhizome rather 
stout, elongate, in nature densely clothed with the black wiry old stems. Stems 
6 inches (in nature more often 2 inches) long, erect, simple, leafy. Leaves linear, 
acute, flattened, about \ inch long by 2Viiich wide. Inflorescence i- to 3-flowered. 
Flowers 4- or 5-parted. Male Flower : — petals linear-lanceolate, blunt, wide- 
spreading, white in the living specimens, usually purple, at least twice the 
sepals ; stamens erect, equalling the petals ; scales oblong, notched, red ; carpels 
lanceolate, erect, yellow, with short styles. 
Flowers June. Hardy. 
Habitat. — Himalayan region, Siberia, Arctic Russia. 
Young plants, raised from seed sent from Darjeeling, seen at 
Edinburgh as the present paper was going to press. Apparently 
not previously in cultivation, though a characteristic Himalayan 
and Siberian species. 
Named from its (usually) quadripartite flowers. 
12. Sedum himalense D. Don (fig. i8). 
S. himalense D. Don, " Prodromus Flor. Nepalensis," 212, 1825. Hooker 
fil. and Thomson in Journ. Linn. Soc, Bot., 2, 97. Clarke in 
Hooker, " Flor. Brit. India," 2, 418. Not S. himalense of many 
gardens, which is S. Douglasii Hooker, a plant of N.W. America, 
not related to the Rhodiolas. 
Among cultivated Sedums this species most resembles, in general 
appearance, 5. tiheticum Hooker f. and Thomson, but it differs from it 
in bearing bracts on the branches of the inflorescence ; the leaves 
are dark green and the stems mostly red, and both are roughish.
