cumbent. Branches elongat Europe (Britain), North Africa,

cording to Bentham) an accidental deformity, occasionally seen 
in gardens, and supposed to have been originally found near 
Croydon, with small, narrow, deeply cut pe has been 
figured under the name of H. surrejanum. The Rock-roses of 
our gardens are chiefly varieties of this species, which, under 
cultivation, varies much in the colour of its flowers. The follow- 
ing are amongst the most distinct of the innumerable forms: 
H. v. barbatum (bearded). l. ovate or elliptic-lanceolate, clothed 
with long white hairs. (S. C. 73.) —— 
H. v. hyssopifolium (Hyssop-leaved). fl. coppery- f 
or saffron-coloured (S. C. 92). ft flat, linear-lanceolate or lanceo- 
late ; upper surface glossy. Of the one with coppery-red flowers, 
there is a double form. : 
H. v. macranthum (large-flowered). fl. whitish, yellow at the 
base ; racemes terminal, secund, simple. Summer. 1. flat, ovate- 
oblong, acutish, densely tomentose beneath, smooth above. 
Branches shrubby, procumbent, rather tomentose. 
H. v. mutabile (changeable). jl. pale rose-colour, yellow at base, 
becoming almost white before petals fall. Summer. (S. C. 106.) — 
H. v. ovalifolium (oval-leaved). fi. yellow. l, lower ones round- 
ish or oval, glossy —* above, white beneath ; margins more or 
less revolute. SYN. H. serpyllifolium. (S. C. 60.) »
