Varieties. Two are mentioned by Do CandoUe ; one of them with the peduncles glabrous, and the 

 other with the branches and peduncles rather hairy. 



Spec. Char., Sfc. Erect, branched. Branches hoary. Cauline leaves obovate, 

 or ovate-oblong, 3-ncrved, almost sessile, green / those of the branches are 

 stalked, and keeled on the back, reflexed at the top, hoary on botii 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 often confused in the collections with H. algarvense, though it is very 

 different. It is a very handsome undershrub, and, being rather tender, re- 

 quu-es the protection of a wall, or a covering of mats during severe frosty 

 weather. 



B. Style almost none. Stigma large.

 the top. Leaves .sessile, tapering towards the base, oblong-ovate, bluntish, covered with short

Spec. Char., Sfc. Erect. Branches rather hairy, clothed with leprous tomen- 

 timi, 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, hair\ , shorter than the leaves. (Don's Mill., \. 

 \).m2.\ A shrub 3 ft. 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 flexuosc; the branches .spreading, more or less hairy; the 

 young shoots reddish ; and the flowers terminal, with broaiUy ovate petals of 

 a golden yellow, each with a large dark s|)ot 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.
