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 S. 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 I 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 J inch long by ^ViJ^ch 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, 18), 



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 5. Douglasii Hooker, a plant of N.W. America, 

 not related to the Rhodiolas. 



Among cultivated Sedums this species most resembles, in general 

 appearance, S. 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,
