Description:
Description - Trees, to 30 m tall, usually unbuttressed, sometimes basally swollen. Bark brown, more or less smooth, with occasional vertical cracks and hoop marks. Leaf blades widely elliptic to elliptic, 8-14 x 4-8 cm, glabrous, punctate abaxially, coriaceous, with 7-10 pairs of lateral veins; apex usually short acuminate, sometimes long acuminate; base acute to obtuse; margins entire; petiole 7-12 mm long. Inflorescences usually terminal, sometimes in leaf axils, simple, racemose, the rachis glabrous, 2-16 cm long, sometimes dull yellow, the flowers widely scattered along its length; pedicels glabrous, (10-) 15-25 mm long. Flowers ca. 3 cm diam.; calyx with six lobes, the lobes very widely ovate, 2-4 x 3-5.5 mm, erect, separate or slightly imbricate, convex abaxially, slightly concave adaxially; petals six, widely obovate, 17-27 x 11-14 mm, white or yellow; hood of androecium 15-17 x 13-17 mm, yellow, forming double coil; staminal ring with 70-120 stamens, the filaments not markedly clavate, 1-1.5 mm long, the anthers 0.3-0.7 mm long; hypanthium gradually tapered into pedicel, glabrous; ovary 2-locular, each locule with 3-8 ovules attached to floor of locule, the style 3 mm long, curved toward anterior end of flower. Fruits depressed turbinate, 3.5-6 x 3.5-6 cm, the calycine ring prominent, inserted above middle, the supracalycine zone erect, narrow, the infracalycine zone convex, the pericarp ca. 5 mm thick; operculum umbonate. Seeds ca. 2.2 x 1.5 cm, with a distinct lateral aril.

Discussion:
Eschweilera collina is a distinctive species characterized by bark and habit, leaf, flower, and fruiting features. The bark is smooth with occasional hoop marks and the trunk is cylindric. The tertiary veins of the abaxial leaf surface are salient which, along with the lustre of the surface, give the leaf a unique appearance. Flowering material is easy to recognize because of the unbranched, short inflorescences, and flowers with long pedicels which gradually taper into the hypanthium. Finally, the fruits of E. collina are thick and very broadly turbinate, with a well developed calycine ring. They are similar to those of E. pedicellata but much thicker and more depressed.
