Stems suffruticose, branched from the base : branches 

 slender, at first upright, but at length becoming procum- 

 bent, as they cannot support their weight, the points as- 

 cending, thickly clothed with loose wool and a few hairs 

 intermixed, the older branches a little warted. Leaves al- 

 ternate, sessile, oblongly ovate, acute, thickly clothed all 

 over with long spreading hairs: upper ones narrowest, 

 sometimes lanceolate, of a dull green colour, not glossy 

 as in H. polygalcefolium. Flowers lateral, solitary, op- 

 posite to a leaf, or terminating the branch in a loose few 

 flowered raceme, which is sometimes forked ; the strong 

 branches sometimes also produce flowering shoots, or 

 racemes in the axils of the upper leaves. Peduncles 

 shorter than the leaves, densely covered with white wool. 

 Bractes none. Calyx of 5 sepals, the points a little re- 

 curved, the 3 inner ones ovate, with long taper points, 

 thickly clothed with dense white wool : the 2 outer ones 

 shorter, very narrow, subulately linear. Petals 5, obcor- 

 date, notched at the points, at first imbricate, afterwards 

 becoming distinct, and widely spreading, of a light yel- 

 low, darker at the base. Stamens from 30 to 32, spread- 

 ing flat at first, afterwards becoming bent inwards: 

 filaments smooth, yellow. Pollen orange-coloured. Ger- 

 men smooth and glossy. Style very short. Stigma very 

 large, capitate, papillose.
