Stem suffruticose, branching in all directions : bran- 

 ches procumbent, their points ascending, thickly clothed 

 with a close pressed canescent tomentum. Leaves op- 

 posite, variable, flat or sometimes very slightly revolute 

 at the margins, underneath clothed with a dense white 

 tomentum, the upper side of a dull glaucous green, oc- 

 casioned by a short close pressed pubescence, scarcely 

 perceptible to the naked eye : lower ones ovately oblong^ 

 flat, obtuse or rounded at the points : upper ones lan- 

 ceolate, acute, when young the margins slightly revo- 

 lute, channelled on the upper side. Petioles pubescent, 

 on the lower leaves about the length of the stipules, on 

 the upper ones shorter. Stipules linear, acute, pubes- 

 cent and ciliate, greener than the leaves. Racemes ter- 

 minal, many-flowered. Bractes linear, fringed, about 

 half the length of the pedicles. Pedicles densely clothed 

 with a close white tomentum, nodding before the flowers 

 expand, scarcely erect when expanded, afterwards re- 

 flexed. Calyx of 5 sepals, smooth, or scarcely pubes- 

 cent, 2 outer ones very small, oblongly lanceolate, blunt- 

 ish, of a brownish purple, inner ones ovate, concave, 

 scarcely acute, membranaceous, strongly four-nerved,
