them entirely glabrous, as are the branchlets. The inflorescence, how- 

 ever, and the calyx are densely silky-canescent or silky-pubescent ; and 

 the flowers are slightly pedicellate, especially the central ones of each 

 cluster. Stamens red. Fruit not seen.

Apparently a tree of considerable size; the branchlets nearly 

 terete, the younger ones only hoary with a fine pubescence. Leaves 

 oval, or broadly elliptical, rarely verging to ovate, rounded at both ends, 

 often retuse, sometimes slightly subcordate, coriaceous, 11 to 2£ inches 

 long, glabrous or early glabrate above, hoary with a minute canescent 

 tomentum underneath, which is very tardily deciduous, closely feather- 

 veined ; the veins slender but perspicuous, reticulated, the basal ones 

 produced into an intramarginal false vein. Petiole rather conspicuous, 

 2h to 4 lines long. Cymes small, solitary or in pairs at the apex of 

 the branches, not exceeding the leaves, very short-peduncled. Bracts 

 caducous. Flowers subsessile or very short-pedicelled (the pedicel less 

 than a line, or rarely a line and a half long, oftener scarcely any), 

 usually in threes at the apex of the partial peduncles. Calyx densely 

 canescent-tomentose, as also the inflorescence, about 2i lines long, cam- 

 panulate-turbinate, five-lobed; the lobes very obtuse. Petals tomen- 

 tulose externally, u yellow, as well as the stamens," apparently pale. 

 Filaments and style nearly an inch long. Ovary nearly as in M.
