Description:
Species Description - Understory trees, to 22 m tall, unbuttressed, the branches at distinct right angles to trunk. Bark brown to reddish brown, often with distinct pock marks lower on trunk, the outer bark =1 mm thick, the inner bark 3-5 mm thick, yellowish brown. Leaves: petioles 6-12 mm long; blades elliptic, 8.5-17 x 3-7.5 cm, chartaceous, glabrous, with 10-14 pairs of lateral veins, venation brochidodromous from base to apex, the marginal vein ca. 5 mm from leaf margin; base acute, obtuse, or rounded; apex long acuminate. Inflorescences axillary or terminal, usually of simple racemes, less frequently weakly once-branched paniculate arrangements of racemes; pedicels 4-8 mm long, puberulous to pubescent. Flowers ca. 2 cm diam.; calyx-lobes 6, imbricate at bases, yellow, 2-2.5 x 2-2.5 mm; petals 6, very light yellow to nearly white; androecial hood yellow, the staminal ring with ca. 200 starpens; ovary 2-locular. Fruits depressed globose, the) calycine ring inserted near middle, the calyx-lobes thickened, the supracalycine zone erect, the infracalycine zone rounded to base, 1.5-2.5 (excluding operculum) x 2.5-3.5 cm, the pericarp lenticellate, 2-3 mm thick. Seeds usually 1 per fruit, round in cross section, 15-25 x 12-15 mm.

Discussion:
Phenology. Flowers in Nov and matures fruit in Jan. Common name. Matamatá mirim. This common name was selected as most appropriate because of the relatively small stature of the species as well as its small fruits. Comments. This species is characterized by its (1) small stature and right-angled branches, (2) bark often with conspicuous but small pock marks, (3) leaves with brochidodromous venation from the base to the apex, and (4) relatively small flowers and fruits.
