separate nearly to the base, slender, narrow, tapering, very acute, spreading. 
Petals white, erect, recurved above, oblong-lanceolate, acuminate, margins 
eroded, more than twice the sepals. Stamens shorter than the petals, filaments 
white, anthers red-purple. Scales small, yellow, quadrate, slightly notched. 
Carpels white, erect, about \ as long as the stamens. 
Flowers June. Hardy. 
Habitat. — N. China. 
This species and 5. Tatarinowii, neither previously in cultivation, 
were sent to Kew in 1913 by Mr. F. N. Meyer of the American 
Legation at Pekin, who collected them at 3,000 metres at Hsiao 
Wutai Shan. 
A variable species, but especially characterized by its white bell- 
shaped flowers with petals prolonged into a slender tail and margins 
usually fringed. S. rariflorum of N. E. Brown, in cultivation at 
Kew, is fairly typical dumulosum. S. Farreri W. W. Smith, raised 
by the late Mr. Farrer from seed collected by him in Kansu, is a 
robust form with long sepals and broad petals much eroded.

A pretty plant with the thickened rootstock of the Rhodiolas, 
but distinct from other species of that section in its broad, deeply- 
incised leaves grouped near the top of the stems, and its lax inflores- 
cence of large red flowers ; and whereas most of the Rhodiola section 
are early flowerers, S. trifidum does not bloom till September. 
Description. — A glabrous herbaceous perennial. Rootstock thick, branched, 
sometimes elongate, but (in cultivation at least) not aerial. Stems several 
together, erect, unbranched, 6-8 inches high, slender, smooth, round, red, bare 
save near the top, or with a few small, entire, club-shaped leaves. Leaves 
alternate, crowded on the terminal i to 2 inches of stem, smooth, green, sessile, 
i|-3 inches long, narrow and linear or tapered in the lower half, expanded 
above into an obovate lamina deeply and irregularly cut and toothed. Inflores- 
cence a very leafy, lax, flat cyme about 2 inches across, of several minutely 
papillose forked branches, upper bracts linear, entire. Buds linear-lanceolate, 
blunt. Flowers f inch across, mostly sessile, the lower shortly stalked. Sepals 
green, very fleshy, blunt, variable in length, ^ to ^ the petals, linear or lanceolate 
to short triangular (fig. 25, a, h). Petals purple-red, linear-lanceolate, apiculate, 
wide-spreading, ultimately reflexed. Stamens purple-red, spreading, slightly 
shorter than the petals. Scales red, cuneate, deeply notched, broader than 
long. Carpels white tinged red, nearly erect, equalling the stamens. 
Flowers August-September. Hardy. 
Habitat. — Himalayas, widely distributed, 6,000-12,000 feet, on 
rocks and trees ; Yunnan. 
A distinct and pleasing plant, and one of the few Sediuns that 
offers some difficulty as regards its cultivation. The best plants 
which I have seen were grown in deep, well-drained crevices not fully 
exposed to the sun. In the Himalayas on mossy tree-trunks or 
rocks it often grows a foot high, with large deeply pinnatifid leaves.
