leaf, deep orange in flower, and red in fruit, the highly pigmented con- 
dition being known in gardens as var. aurantiacum ; it forms a hand- 
some plant, and for cultural purposes deserves its distinguishing name. 
Var. scabrum Maximowicz is scabro-papillose throughout, and 
common in some parts of China ; but I have not observed any tendency 
in this direction among the cultivated forms. 
Aizoon is the name of a genus of Portulaceae. The word signifies 
" always alive," and its application to a species of Sedum is obvious. 
Hybrid S. Aizoon X kamtschaticum hybr. no v. (fig. 57). 
Description. — Rootstock twiggy like kamtschaticum. rather than woody like 
Aizoon. New shoots arising in autumn from points near the base of the old 
stems and remaining short and leafy during the winter, as in kamtschaticum, not 
arising in spring from points on the woody rootstock as in Aizoon. Stems de- 
cumbent or ascending at base, remainder erect, resembling kamtschaticum below 
and Aizoon above, 6-8 inches long. Leaves lanceolate, serrate, in shape and 
colour identical with some Aizoon forms, not oblanceolate as in kamtschaticum, 
less toothed than typical Aizoon. Inflorescence rather lax, very leafy, of three 
dichotomous branches with flowers in the forks, resembling kamtschaticum 
rather than Aizoon. Flowers rich orange-yellow, ^— | inch across, rather larger 
and brighter than typical Aizoon ; in relative length of sepal to petal agreeing 
with kamtschaticum, not with Aizoon. Flowers in June, along with kamtschaticum , 
a fortnight heiore Aizoon. Fruit aborted, seeds sterile. 
Hybrids are so rare in the genus Sedum that this plant is of some 
interest. 5. Aizoon is a very variable species, but the exactly inter- 
mediate character of the present plant as between the two suggested 
parents, and the infertile seeds, render its hybrid origin almost certain, 
since 5. Aizoon does not vary perceptibly in the direction of kam- 
tschaticum, and since both parents are normally very free in their 
production of seed. 
Probably a natural hybrid of garden origin. Received from 
Wisley (no. 45/15) as kamtschaticum, and a plant practically identical 
was seen in the Cambridge Botanic Garden.

Nearest to 5. Aizopn, which it resembles in habit, but easily known 
by its very hairy stems, hairy narrower leaves, and more numerous 
smaller flowers. 
Description. — A hairy herbaceous perennial. Stents annual, arising in 
autumn, erect, i-i^ foot high, rather slender, round, purplish, shaggy with 
spreading or deflexed white hairs half as long as the diameter of the stem ; barren 
stems none. Leaves, alternate, flat, scarcely fleshy, sessile, bluntly pointed, 
toothed in upper half, dark shining green, finely hairy on both faces, ciliate, 
midrib hairy below, about 2 inches long, the lower lanceolate-oblong narrowed 
at base, the upper linear-oblong rounded at base. Inflorescence a large, very 
leafy dense umbellate cyme, 2-4 inches across, of about 5 twice-branched hairy 
branches ; uppermost bracts lanceolate, very small. Buds ovate, acute, with
