ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 251 
Not hardy. 
Habitat. — Cerro San Filipe, Oaxaca, Mexico. 
Material sent from Washington (under the name S. diver sifolium 
Rose), has grown freely but has never flowered, and the description 
of the flower given above is quoted from Rose [loc. cit.). 
Derives its name from its habitat, Oaxaca.

The only one of several interesting endemic Madeiran species 
which is in cultivation. The present plant has green, egg-shaped leaves 
(pale green in the plants I have seen), resembling those of short-leaved 
forms of S. album, and few-flowered cymes of small greenish-yellow 
flowers. In nature it forms a low, tangled subshrub, but the culti- 
vated plant has weak, sinuous stems which sprawl on the ground. 
It is closely allied to 5. lancerottense R. P. Murray, which is confined 
to Teneriffe ; the differences between the two are discussed under 
the latter species. 
Description. — A small, glabrous evergreen. Stems sinuous, in nature woody 
and forming a low subshrub, in cultivation weak, sprawling and occasionally 
rooting, bare below, with many ascending leafy shoots a few inches long. Leaves 
green or glaucous, sessile, obovate-oblong, very blunt, nearly terete, slightly 
flattened on face, alternate, set at right angles to the stem, up to f inch long by 
broad and thick. Inflorescence a small few-flowered cyme, generally of 2 or 3 
simple branches with a central flower, flowers about 4 to 10 in all, bracts 
resembling the leaves. Buds ovate, blunt, with greenish ribs. Flowers up to | 
inch across, the lowest on a pedicel longer than the flower, the uppermost sessile. 
Sepals resembling the leaves, green, very fleshy, unequal, wide-spreading, obovate, 
very blunt, almost exactly egg-shaped, not spurred. Petals nearly twice the 
sepals, linear-lanceolate, rather bluntish, wide-spreading, greenish yellow, 
keeled. Stamens 10, spreading, shorter than the petals, filaments yellow, 
anthers brownish yellow. Scales orange, cuneate, notched, \ the carpels. Carpels 
divergent even in bud, wide-spreading later, greenish yellow, styles slender ; 
stellate in fruit, when they are surrounded by the very swollen, unequal sepals. 
Flowers May (Kew, gentle heat) ; June (cold frame). Not hardy. 
Habitat. — Madeira. 
De Candolle states that it flowers in summer at Kew, in winter 
at the Jardin des Plantes. It is a shy bloomer in cultivation, and 
the flowers which I was fortunate enough to get at Kew were the first 
that had been noticed on the plant, which has been long in culti- 
vation there. De Candolle states that Masson, who discovered 
it, sent it to England in 1777. Aiton ("Hortus Kewensis ") states 
that it was received at Kew in that year. The plant, as cultivated 
there now, is quite possibly derived from" the original stock. Lowe 
says the leaves are generally bright full green, occasionally pale or 
glaucous. The Kew plant is pale green, and produced as many as 
sixteen flowers on the inflorescence, the three branches of which were 
forked.
