ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 49 
recognizable by its entire heart-shaped leaves, which vary chiefly as 
regards their length. 
Description. — A glabrous herbaceous perennial without barren shoots. 
Rootstock massive, branched, the greater part subterranean (in cultivation). Stems 
annual, erect, several together, 9-12 inches long, slender, smooth, unbranched. 
Leaves alternate, rather distant, fleshy, triangular-ovate, ovate, or ovate - 
lanceolate, acute or blunt, sessile, cordate, |-i inch long by J-^ inch or more 
broad, green, paler on back, tip often red. Inflorescence a flat, lax, leafy cyme, 
1-3 inches across. Buds obovate or nearly globular, blunt or apiculate, ribbed, 
the clasping sepals occupying grooves between the petals. Flowers 5-parted, 
J inch across. Male flower : — sepals linear, streaked dark purple outside, 
greenish or purple inside, tube short ; petals i\ times the sepals, oblanceolate, 
non-contiguous, spreading, often reflexed, dark brownish purple or streaked 
purple and green ; stamens reddish purple, shorter than the petals ; scales 
conspicuous, dark shining purple, quadrate, often retuse, reflexed ; carpels' 
minute, erect, greenish, equalling the scales. Female flower : — sepals similar 
to the male ; petals more linear ; stamens absent ; scales similar to the male ; 
carpels large, purple, with short, blunt, linear spreading styles. 
Flowers June. Hardy. 
Habitat. — Himalayas, 10,000-12,000 feet. 
Rare in cultivation. I have it from Kew, Edinburgh, and the 
Lissadell nursery in Co. Sligo, all these plants having their origin in 
the Darjeeling Botanic Garden, whence I have also received it direct. 
It also came from Messrs. House & Son of Bristol under the name 
of 5. Hookeri. The male plant (which is much the more attractive) 
is commoner in cultivation than the female, which I have seen at 
Edinburgh, and have raised from Darjeeling seed. 
The specific name recalls the resemblance of the plant to some 
species of Bupleurum, a pecuHar genus of UmbelUferae.

A Himalayan Rhodiola which in appearance comes nearest to 
S. himalense D. Don, but it is usually glaucous and smooth, while 
himalense is mostly dark green and rough on leaf and stem. 5. 
tiheticum also belongs to the group which has the inflorescence branches 
bare of leaves, while those of himalense are leafy. Both have usually 
dark-purple flowers, and are much slenderer than S. roseum, and 
much larger than 5. fastigiatum. 
Description. — A glabrous herbaceous perennial. Rootstock thick, erect, 
branched. Stems many, from the scales at apex of rootstock, annual, simple, 
smooth, round, reddish, slender, leafy, 6-9 inches long. Leaves alternate, longer 
than the intemodes, patent, sessile, lanceolate to oblong, rounded at base, acute, 
mostly lightly toothed in upper part, generally rather glaucous, pale on back, 
about I inch long. Inflorescence terminal, flattish, rather lax, 1-2 inches across, 
leafless or with few bracts at base of branches ; branches several, forked. Flowers 
dark purple, | inch across. Female flower : — calyx saucer-shaped, purple or 
green, lobes long-triangular, rather acute, exceeding the tube ; petals lanceolate, 
acute, nearly twice the sepals, dark purple, wide-spreading ; scales black-purple, 
oblong, blunt, erect, equalHng or exceeding in length and breadth the sepals 
which cover their backs ; carpels erect, oblong, equalling the petals, i^^h long, 
purple, the tips and the very short styles divergent.
