rather tomentose, canescent. Leaves flat, o r hardly revolute a t the margins ;
under surface tomentosely hoary, upper surface greenish glaucous. Lower
leaves ovate oblong, obtuse; upper ones lanceolate, acute. Stipules linear,

A splendid plant, with reddish crimson flowers ;
the petals imbricated, and having a small orange spot
a t the base of each. Sweet considers it as having the ^
darkest-coloured, if not the handsomest, flowers o f '
the genus. The flowers are also, he says, very large
for the size o f the plant. I t is nearly related to H.
rhodanthum, but is readily distinguished from it by its 92. h . canéscens.

Lower leaves oval ; upper ones oblong-lanceolate, green on both snrfaces,
flat, hairy. Calyxes hairy. Petals imbricate. (Doris Mill.) A subevergreen
suffruticose nndershrub, with the branches ascending. Originated

Vaiieties.
Í- H . h. I crocàtum (Swt. Cist., t. 92.) has
flowers saffron-coloured, with more or less
of a ferrugineous tint, and may represent
the species.
u H. h. 2 cùpreum (Swt. Cist., t. 58.) has I
flowers of a reddish copper-colour.
H. h. 3 multiplex (Sw t. Cist., t. 72.; and qur
fig. 93.) has double flowers, of a reddish
copper-colour.
All the three forms of this variety are splendid
plants ; they are hardy, of luxuriant growth, flowering
freely, and of the easiest culture, either in pots
or on banks of light sandy soil, covered with flints „
or stones. The flowers of the copper-coloured va- ’ ' _
rietv, and also the leaves, are larger than those of the two other kinds. The
double-flowered variety appears to be of a more upright habit of growth,
and not quite so robust as the others.

Spec. Char., 4c . Erectish. Branches pilosely tomentose,
scabrous, canescent. Leaves sessile,
tapering to the base, oblong-ovate, acutish,
roughish, 3-nerved, with waved revolute margins ;
upjier surface green, under surface clothed with
grey tomentum. Peduncles terminal, 1—2-flow-
ered, shorter than the leaves. Calyx 3-sepaled,
hairy. Petals distinct. (Doris Mill.) A sub-evergreen
erect nndershrub. Portugal. Height 2 ft.
to 3 ft. Introduced in 1775. Flowers rich yellow ;
June to August. Capsule brown ; ripe in Sept.
Differs from most other species of Heliánthemum,
in growing erect. It forms a very handsome littlebusli,
but it requires a sheltered situation, and a dry soil.
Many other Kinds o f Helianthemums described in Sweet’s Cistinece are, perhaps,
as hardy as those we have selected ; but it would be of little use giving them here,
the greater part having been lost during the winter of 1837-8. In the first
edition of this Arboretum 99 species are described, besides varieties. Supposing
a cultivator about to form a collection of Cistàceae, we should attach
much less importance to his being able to procure all the sorts of Cistus and
Heliánthemum described in Sweet’s Cistinece, than to his obtaining all the sorts
easily procurable, whatever names they might pass under, and cross-fecundating
them so as to produce new forms. There can be no doubt whatever that
the sorts of both the genera Cistus and Fleliánthemum might, by cross-fecundation,
be increased ad infinitum; and, considering their very great beauty
as border and rockwork shrubs, we think they merit the attention of cultivators
at least as much as many florist’s flowers.
