ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 227 



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



the Japanese 5. 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. sarmeniosum variegatum, or S. carneum variegaium, is a form of 



S. lineare, not of sarmeniosum (see p. 229). 



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

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

 tip and occasionally elsewhere, often branched, in the open usually dymg m 

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

 riches) unbranched. Leaves temate. broadly lanceolate acute, bright green, 

 flat fleshy, entire. sessUe. i by i inch, with a semicircular membranous ad- 

 pre^sed spur, those of the barren and flowering shoots similar. Inflorescence a, 

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

 ovate acute. Flowers sessile save the lowest, * to f inch across. Sepals equa or 

 nearly so, Unear-lanceolate. green, fleshy, blunt, separate to the base. Petais 

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

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

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

 Juadrate, slightly notched. Carpels yellow, compressed, equallmg the stamens, 

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



Flowers July. Hardy. 



Habitat.— North China, Japan. 



Rather rare in cultivation. The name sarmeniosum (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 sarmeniosum variegaium and carneum variegaium. 

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

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

 seen, and by good dried specimens in the Edinburgh 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- 

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

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

 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 in 5. sarmentosum ; flower-stems about 6 inches, not shorter than the ascending 

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

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

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

 terminal, lax. flat, umbellate, ij inch across, of a central, short-stalked flower
