the flowering ones branched below, 2^-3 inches long. Leaves alternate, sessile, 
imbricate, linear, entire, acuminate, \ to\ 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. 
Flowers September. Hardy. 
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. 
127. Sedum Celiac Hamet (fig. 153). 
S. Celiac Hamet in Bulletin de Geographic Botanique, 23, 67, 1913. 
A minute, green, spiny-leaved species allied to the well-known 
Himalayan (and Chinese) S. muUicaule 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 muUicaule 
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 with 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 inch wide by i^^h 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, 3^ inch long, with a dorsal rib ending 
in a short apiculus behind and slightly exceeding the tip (fig. 153, c). Staviens 
a little shorter than the petals, filaments tapering, yellow, anthers reddish purple, 
the epipetalous ones inserted about J 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.
