MERRILL. 
to 18 cm wide, very thickly coriaceous, somewhat shining, when dry 
minutely and densely rugose on both surfaces, the apex rather broadly 
rounded, sometimes slightly refuse, the base acute or somewhat acuminate, 
rarely broadly rounded; nerves about 10 on each side of; the midrib, 
distinct, anastomosing, the reticulations lax ; petioles stout, 1 to 2 cm long ; 
stipules very broadly ovate, abruptly acuminate, 5 to 7 mm long, deciduous. 
Inflorescence terminal, puberulent, corymbose, subtended -by one or two 
pairs of broadly ovate, abruptly acuminate bracts 8 mm long or less, with 
two lateral basal branches, the rachis short, trichotomously branched, the 
primary branches stout, 3 to 5 cm long, all subtrichotomously branched at 
their apices, forming a rather dense inflorescence about 9 cm long, and 
as wide or wider than long. Flowers white or greenish- white, rather 
densely crowded at the ends of the ultimate branchlets, their pedicels 1 
to 2 mm long, ebracteolate. Calyx ovoid, puberulent, about 2 mm long, 
with 4 short, broadly ovate, acute teeth about 0.3 mm long. Corolla-tube 
rather slender, 2.4 cm long, 2 mm wide when more or less flattened out, 
the lobes 4, spreading or reflexed, oblong, rounded, 7 mm long, 4 mm 
wide. Anthers linear, 5 mm long, the filaments exserted about 3 mm. 
Style slender, exserted about 6 mm, the arms thickened, more or less 
flattened, about 2 mm long.

An erect shrub or tree 3 to 8 m high, glabrous except the inflorescence 
which is' usually puberulent. Branches terete, gray, the younger ones
