This species and S. 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

A variable species, but especially characterized by its white bell- 

 shaped flowers with petals prolonged into a slender tail and margins 

 usually fringed. S. rariflomm of N. E. Brown, m cultivation at 

 Kew is fairly typical dumulosum. S. Farreri W. W. Smith, raised 

 by the late Mr. Farrer from seed collected by him m 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 mflores- 

 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, 

 som^tir^es elongate, but (in cultivation at least) not aenal. Stems several

A distinct and pleasing plant, and one of the few Sedums that 

 offers some difiiculty 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.
