ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 227 



arranged in threes, and short flowering stems. Its .nearest ally is 

 the Japanese S. lineare, which is of similar appearance, but has longer 

 leaves only half as broad and flowering stems several times taller ; 

 it is, moreover, tender, and unable to endure the winter out of doors. 

 The variegated Sedum grown in greenhouses under the name of 

 5. sarmentosum variegatum, or S. carneum variegatum, is a form of 

 5. lineare, not of sarmentosum (see p. 229). 



Description. — A glabrous, evergreen, prostrate perennial. Stems smooth, 

 round, reddish ; barren shoots long (to i foot or more), prostrate, rooting at the 

 tip and occasionally elsewhere, often branched, in the open usually dying in 

 winter save for the rooted base and tip ; flowering shoots ascending, short (about 

 3 inches), unbranched. Leaves temate. broadly lanceolate, acute, bright green, 

 flat, fleshy, entire, sessile, i by J inch, with a semicircular membranous ad- 

 pressed spur, those of the barren and flowering shoots similar. Inflorescence a 

 flat, rather lax. leafy cyme, of 3 often forked branches, 2 inches across. Buds 

 ovate, acute. Flowers sessile save the lowest. J to | inch across. Sepals equal or 

 nearly so. linear-lanceolate, green, fleshy, blunt, separate to the base. Petals 

 bright yellow, linear-lanceolate, acute, wide-spreading, equalling the sepals or 

 i longer than them. Stamens spreading, shorter than the petals, filaments 

 yellow, anthers yellow on the faces, red on the edges. Scales small, whitish, 

 quadrate, slightly notched. Carpels yellow, compressed, equalling the stamens, 

 in fruit spreading, overtopped by the large persistent calyx ; styles tapering. 



Flowers July. Hardy. 



Habitat.— North China, Japan. 



Rather rare in cultivation. The name sarmentosum (Latin twiggy) 

 is used in botany to signify the producing of runners as in the straw- 

 berry, and refers to the character of the barren shoots, which are 

 very unusual in Sedum, though matched to some extent in its close 

 ally S. lineare, and exceeded in the Mexican 5. longipes.

The variegated form of this species has been long in cultivation 

 under the names of sarmentosum variegatum and carneum variegatum. 

 This form, which is well known, is more compact and stouter in growth 

 than the type, as represented by the only living plant which I have 

 seen, and by good dried specimens in the Edmburgh Herbarium. I 

 had a long hunt for this (the type), but finally found it in one of the 

 houses at Dahlem (Berlin Botanic Garden) under the name of sar- 

 mentosum, to which the present species is closely allied, but from 

 which it is at all times distinguishable by its much narrower, longer 

 leaves, taller flower-stems, and other characters. 



Description.— A straggling, glabrous, evergreen perennial. Stem weak 

 decumbent and sometimes rooting below, reddish, round, smooth, branches 

 mostly ascending, but barren shoots sometimes elongate, prostrate, and rooting 

 as m S. sarmentosum ; flower-stems about 6 inches, not shorter than the ascending 

 barren shoots. Leaves temate. hnear to linear-lanceolate, rather light green 

 flat on face, paler and rounded on back, bluntly pointed, sessile, shortly spurred' 

 ascending i-i by J inch, mostly exceeding the intemodes. Inflorescence 

 termmal, lax, flat. umbeUate. ij inch across, of a central, short-stalked flower
