Description:
Species Description - A small tree, the young branchlets, leaves and inflorescence thinly covered with very slender silky pale coppery hairs 1-1.3 mm long; mature leaves unknown; halfgrown leaves at flowering time ehiptic, entire, 2.5-3.5 cm long, 1-1.5 cm wide, gradually acuminate at apex, acute at base, on silky petioles 2-3 mm long; midvein glabrous and nearly flat above, elevated and silky beneath; lateral veins 5-6 on each side, ascending, overarching and forming a poorly defined marginal vein 1-2 mm from the margin (i.e., % - % the distance from margin to midvein); veinlets forming a coarse reticulum; glands not apparent on the young leaves; flowers arising with the new leafy branchlets when these are 3-4 cm long or often much less, borne in 1-2 opposite approximate pairs at the lowermost (leafless) nodes of the new branchlets; pedicels filiform, 2-3 cm long, subtended by imbricated scarious reddish-brown ovate, obtuse, deciduous bracts 4-6 mm long and up to 5 mm wide; bracteoles minute, scarious, linear, 0.5-1.5 mm long, situated on the pedicel 3-5 mm below the base of the hypanthium, deciduous at anthesis; hypanthium campanulate, 1.5 mm long, densely silky, prominently 8-ridged even in the young flower; calyx-lobes 4, membranous, triangular-ovate, 3-3.5 mm long, 2-2.5 mm wide at base, obtusely rounded at apex, glabrous within, silky on the outer surface and fimbriate-silky at apex; disk 1.5-2.5 mm wide, flat or concave when dry, glabrous except the staminal ring; style 5 mm long; stamens about 75; petals white, obovate, 6-7 mm long; fruit not seen; ovary bilocular, with 1-3 ascending collateral ovules in each locule.

Discussion:
Stenocalyx dentatus Berg,Mart. Fl. Bras. 14(1): 338. 1857
Berg stated in the protologue that this plant differed from all the other species [presumably of this group of Stenocalyx] in its crenate-repand or crenate-dentate leaves. The leaves in the type are entire, but in some of them short portions of the margins have been turned under in crescent-shaped scallops, evidently the basis for Berg's observation.
