ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 261 



the flowering ones branched below, 2J-3 inches long. Leaves alternate, sessile, 

 imbricate, linear, entire, acuminate, J to J inch long, broadening at the base into 

 a 3-lobed spur. Inflorescence corymbose, dense, up to i inch across, bracts 

 resembling the leaves. Flowers whitish yellow, \ inch across, nearly sessile. 

 Sepals broadly lanceolate, acute. Petals slightly exceeding the sepals, ^ inch 

 long, clawed ; claw linear, a little shorter than the ovate, acute, mucronate, 

 keeled lamina. Stamens 10, about f the petals, the epipetalous ones inserted 

 a little less than half way up the petal. Scales a little longer than broad, retuse. 

 Carpels a little shorter than the stamens, connate in the lower half, styles slender.

Habitat. — Himalayan region ; Yunnan. 



A little, mossy, pale-flowered Sedum of no horticultural interest. 

 My plants, which came from the Lloyd Botanic Garden, Darjeeling, 

 died off badly in autumn just before flowering, and proved difficult 

 to keep. The description of the floral parts given above is drawn 

 largely from Hamet's excellent account. 



Hooker and Thomson call the species annual, and Hamet 

 perennial. My plants persisted for three seasons, but, though barren 

 stems were present, almost the whole perished in early autumn, only 

 a few small buds — whether terminal or axillary I cannot say — 

 remaining till spring, when they rooted and grew.

A minute, green, spiny-leaved species allied to the well-known 

 Himalayan (and Chinese) 5. mullicaule Wall., and forming one of a quite 

 large group of Small linear-leaved species of the Japonica section 

 now known to occur in China. None of its allies except mullicaule 

 and, trullipetalum are in cultivation. The first differs from it in 

 its stellate fruit, much larger leaves, &c., the second in its dense 

 inflorescence, whitish-yellow clawed petals, &c. 



Description. — Perennial, minute, glabrous, bright green, creeping, about 

 2 inches high. Stem creeping, slender, smooth, round, reddish, barren and 

 flowering ones similar, each witii many short ascending branches, their lower part 

 loosely clothed with old leaves. Leaves alternate, crowded, sessile, linear or 

 slightly tapering, entire, acuminate, spine-pointed, thick (fig. 153, b), J inch 

 long by ^^2 inch wide by -^-^ inch thick, at base colourless with a median purple 

 stripe or blotch, spur short, usually rounded, sometimes 3-lobed (fig. 153, a, a), 

 occasionally deeply 3-lobed. Cymes lax, of 2 or 3 short, wide-spreading branches 

 round a central flower, about i inch across, flat, leafy, with bracts forming a 

 rough involucre round the base of the calyx of each flower. Buds ovate, acute, 

 whitish, with green ribs in the upper part, the corolla exceeded by the long, green, 

 erect sepals. Flowers sessile, rather greenish yellow, not opening widely, about 

 J inch across. Sepals lanceolate, acute, leaf-like, scarcely spurred, semi-erect, 

 slightly exceeding the petals (or slightly shorter than them — R. Hamet). Petals 

 yellow, ovate- lanceolate, acute, semi-erect, -^ inch long, with a dorsal rib ending 

 in a short apiculus behind and slightly exceeding the tip (fig. 153, c). Stamens 

 a little shorter than the petals,- filaments tapering, yellow, anthers reddish purple, 

 the epipetalous ones inserted about \ from the base. Scales yellow, the lower 

 half broadly linear, twice as long as broad, the upper half roundish, emarginate, 

 broader than long. Carpels slender, erect, free save at the very base, slightly 

 shorter than the stamens, pale green, tapering into slender erect styles. Seeds 

 attached to a small, semiglobular placenta placed near the base of the inner face 

 of the carpel (fig. 153, d). Carpels erect in fruit, slightly exceeded by the 

 erect sepals.
