double flowers. Malvaecum and supérbum are amongst the 
best. R. Gordowidanum, having red flowers tinged with yellow, 
is a hybrid between this and the following species, partaking 
of the characters of both, but less desirable than either of the 
parent species. 
2. R. atwreum.— Leaves glabrous, shining, irregularly 
lobed. Flowers yellow, the small petals bordered with red. 
The habit of this is more spreading than in the preceding. It 
is also a native of North America. 
Spiny Species. 
3. R. speciosum, syn. KR, fuchsioides.—This is an extremely 
handsome shrub with small irregularly toothed and lobed 
oblong leaves and crimson flowers remarkable for the long ex- 
serted stamens, resembling in this respect some of the Fuchsias. 
The whole plant is more or less spiny and glandular-hispid. 
A native of California, flowering in Spring. 
4, R. niveum.—-Similar in habit and foliage to the last, but 
with smaller white axillary flowers having exserted though less 
conspicuous stamens. It is also from the same regions. 
Orxper XL.—CRASSULACE. 
Usually fleshy herbs with alternate or opposite leaves, often 
crowded at the extremities of the branches in rosettes; stipules 
none. Flowers regular, cymose. Sepals free, persistent, 3 to 
5, rarely more; petals of the same number, free or connate. 
Stamens perigynous, or almost hypogynous, as many or twice 
as many. as the petals. Carpels 3 to 5, seldom more, free, 
many-seeded ; seed small, albuminous. About 400 species, in 
14 genera, chiefly from temperate and warm countries, rare in 
Australasia. Most of the members of this family are only 
suitable for rock-work or in very dry soil, but a few species are 
familiar, and some have lately been introduced into the geo- 
metrical flower-garden to contrast with its highly coloured 
occupants. Echeveria aetdllicais one of the most conspicuous 
of this class. 7 
1. CRASSULA. 
Dwarf herbs, rarely frutescent. Petals 5, free, or connate at 
the base only. Stamens and carpels of the same number. 
Leaves sessile, opposite, usually more or less fleshy, entire,
