Varieties. Two are mentioned by De Candolle; one of them with the peduncles glabrous, and the 
other with the branches and peduncles rather hairy. 
Spec. Char., §c. Erect, branched. Branches hoary. Cauline leaves oboyate, 
or ovate-oblong, 3-nerved, almost sessile, green ; these of the branches are 
stalked, and keeled on the back, reflexed at the top, hoary on both surfaces, 
Peduncles long, branched, paniculate. Pedicels opposite, somewhat um- 
bellate. Calyx of 3 much-pointed sepals. (Don’s Mill., i. p. 302.) A shrub 
growing to the height of 3 ft.,a native of Spain and Portugal; but when 
introduced into England is uncertain. According to Sweet, this species is 
very oiten confused in the collections with H. algarvénse, though it is very 
different. It is a very handsome undershrub, and, being rather tender, re- 
quires the protection of a wall, or a covering of mats during severe frosty 
weather. 
B. Style almost none. Stigma large.

Spec. Char., &§c. Erect, much branched, diffuse, spreading. Branches hoary, tomentosely hairy at 
the top. Leaves sessile, tapering towards the base, oblong-ovate, bluntish, covered with short 
hairs ; younger ones rather hoary, adult ones green. Peduncles terminal, solitary, or umbellat 
1—2-flowered, longer than the leaves. Calyx 3-sepaled, acuminated, hairy. (Don’s Mill., i. p. 302. 
-A shrub, native of Spain and the west of France, growing to the height of 3 ft., and producing its 
yellow flowers from June to August. It is remarked of the flower-buds, that they are of an in- 
tense purple colour at the apex. It does not appear to be in cultivation in British gardens.

Spec. Char., §c. Erect. Branches rather hairy, clothed with leprous tomen- 
tum, scabrous, of a brownish grey colour. Leaves sessile, tapering into 
the footstalks at the base, obovate-oblong, bluntish, rather oblique, with the 
margins somewhat denticulated, and a little curled, tomentose on both 
surfaces, wrinkled, under surface hoary. Peduncles terminal, axillary, or 
umbellate, 1—3-flowered, hairy, shorter than the leaves, (Don’s Mill, i. 
p. 302.) Ashrub 3ft. high, a native of Spain, introduced in 1800, and 
producing its fine yellow flowers from June to August. Its stem is shrubby, 
erect, or a little flexuose; the branches spreading, more or less hairy; the 
young shoots reddish; and the flowers terminal, with broadly ovate petals of 
a golden yellow, each with a large dark spot near the base. It is dis- 
tinguished from all other sorts by the stiff bristle-like purple hairs of its 
calyx. It is rather tender, but it will amply repay protection, either against 
a wall or in a pit. Plants were in the Bristol Nursery in 1827.
