Vl. CISTACE: HELIA NTHEMUM. 6! 
Spec. Char., $c. Stem suffruticose, ascending. Branches hairy-tomentose. 
Lower leaves oval; upper ones oblong-lanceolate, green on both surfaces, 
flat, hairy. Calyxes hairy. Petals imbricate. (Don’s Mill.) A sub- 
evergreen suffruticose undershrub, with the branches ascending. _ Origi- 
nated in gardens. Height 1 ft. to 12 ft. Cultivated in 1827. Flowers 
variable from _satlron to red; May to August. Capsule brown ; ripe in 
September. Varying considerably by culture. 
Varieties, 
% H. h. 1 ecrocdtum (Swt. Cist., t. 92.) has 
flowers saffron-coloured, with more or less 
of a ferrugineous tint, and may represent 
the species. Ae 
2 H. h. 2 cipreum (Swt. Cist., t. 58.) has ait 
flowers of a reddish copper-colour. 
2. H. h. 3 miltipler (Swt. Cist., t. 72.; and our 
Jig. 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, flower- 
ing freely, and of the easiest culture, either in pots 
or on banks of light sandy soil, covered with flints LA 
or stones. The flowers of the copper-coloured va- 99 H- (s-) Ayssopifolium. 
riety, 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., §c. Erectish. Branches pilosely to- 
Mentose, scabrous, canescent. Leaves sessile, 
tapering to the base, oblong-ovate, acutish, 
roughish, 3-nerved, with waved revolute margins ; 
upper surface green, under surface clothed with 
grey tomentum. Peduncles terminal, 1—2-flow- 
ered, shorter than the leaves. Calyx 3-sepaled, 
hairy. Petals distinct. (Don’s Mill.) A sub-ever- 
green erect undershrub. Portugal. Height 2 ft. 
to 3ft. Introduced in 1775. Flowers rich yellow ; 
June to August. Capsule brown; ripe in Sept. 
Differs from most other species of Helidnthemum, 
in growing erect. It forms a very handsome little bush, 
but it requires a sheltered situation, and a dry soil. 
94. H. scabrosum. 
Many other Kinds of Helianthemums described in Sweet's Cistinee 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. Sup- 
posing a cultivator about to form a collection of Cistacez, we should attach 
much less importance to his being able to procure all the sorts of Cistus and 
Helianthemum described in Sweet’s Cistinee, than to his obtaining all the sorts 
easily procurable, whatever names they might pass under, and cross-fecunda- 
ting them so as to produce new forms. There can be no doubt whatever that 
the sorts of both the genera C{stus and Helianthemum might, by cross-fe- 
cundation, be increased ad infinitum ; and, considering their very great beauty 
as border and rovkwork shrubs, we think they merit the attention of culti- 
vators at least as much as many florist’s flowers,
