Description:
Description - Trees, to 35 m tall, without buttresses, the young branches glabrous, rugulose. Leaf blades oblong to oblong-elliptic, 8-18 x 4.5-8.5 cm, chartaceous, glabrous on both surfaces; midrib prominulous above, very prominent beneath, with a few hispid hairs beneath; secondary veins 12-16 pairs, prominulous above, prominent beneath; apex rounded to acute or rarely bluntly acuminate; base subcuneate; margins undulate and slightly crenulate; petiole 14-32 mm long, glabrous, slightly canaliculate, rugulose. Inflorescences of terminal or axillary racemes, the rachis shortly tomentose, 1-9 cm long; bracts triangular, membranous, caducous, 0.5-2 mm long; pedicels 25-33 mm long, slender, glabrous to sparsely puberulous. Flowering in almost leafless condition. Flowers with hypanthium campanulate, ca. 7 mm long; calyx lobes six, ovate triangular, acute, sparsely puberulous on both surfaces, the margins ciliate; petals oblong, unequal, 2.5-3.5 cm long, sparsely and shortly puberulous and punctate on exterior, glabrous, dark red-wine colored; androecium ca. 4 cm long, the staminal ring 15-18 mm diam., the exterior of hood rugulose-pustulate, the stamens ca. 35-40, tightly clustered in two rows around staminal ring, not extending up ligule, purple with yellow at base of exterior. Fruits not seen.

Discussion:
This species is close to Couratari multiflora. For their differences see discussion of section Microcarpa. It is pollinated by Eulaema meriana, a large euglossine bee (Prance & Anderson, 1976).
