Stem suffrutescent, procumbent, very much branch- 

 ing : branches ascending or erect, clothed when young 

 with a close white down, this wears off by age, and 

 they then become smooth. Leaves opposite, petiolate, 

 lanceolate, acute, slightly revolute at the margins, green 

 and rather glossy on the upper side, but clothed with 

 short hairs, most abundant on the young leaves, under- 

 neath clothed with a short white tomentum. Petioles 

 short, flattened a little on the upper side, hairy. Stipules 

 about twice the length of the petioles, linearly subulate, 

 hairy and fringed. Racemes terminal, many-flowered, 

 nodding and involute before the flowers expand, but 

 becoming erect as they come into bloom ; the flower- 

 stem thickly clothed with white down. Brae tes linearly 

 lanceolate, acute, hairy and fringed, nearly as long as 

 the pedicles, and sometimes exceeding some of them in 

 length. Pedicles densely tomentose, drooping before the 

 flow r ers expand, erect when in bloom, afterwards reflex- 

 ed. Calyx inflated, of 5 sepals, the two outer ones very 

 small, bluntish, of a dark green : inner ones short, ovate, 

 concave, blunt, 3 to 5-veined or striate, somewhat glossy
