Description:
Description - Trees, to 30 m tall, unbuttressed or buttressed. Bark gray, brown or reddish-brown, with irregular depressions left by sloughing plates. Leaf blades elliptic, 10.5-22 x 4-10 cm, glabrous, coriaceous, with 10-15 pairs of lateral veins, the tertiary veins salient on abaxial surface; apex acuminate; base obtuse; margins entire; petiole 8-15 mm long. Inflorescences terminal or axillary, usually once branched paniculate arrangement of racemes, the principal rachis 4.5-13 cm long, glabrous or puberulous, the pedicels 5-12 mm long, usually puberulous. Flowers 2.5 cm diam.; calyx with six lobes, the lobes widely ovate, 3.5-4.5 x 2.5-3.5 mm, spreading to ascending, not or scarcely imbricate, thick, convex to carinate abaxially, flat adaxially; petals six, white, widely obovate, 12-15 x 9-12 mm; hood of androecium 10-12 x 12-14 mm, with double coil, with distinct groove on marginal, exterior, anterior surface, light yellow; staminal ring asymmetric, with 116-130 stamens, the filaments 1 mm long, not markedly clavate, white, the anthers 0.5 mm long; hypanthium abruptly constricted to pedicel; ovary 2-locular, each with 45 basally attached ovules, the style obconical, erect or oblique, 1-2 mm long, not well-differentiated from summit. Fruits cup-shaped, the calycine ring inserted near apex of fruit base, the infracalycine zone rounded to pedicel, the pedicel often persisting as woody knob, 2-3 x 4-5.5 cm (excluding operculum and pedicel), the pericarp 5-6 mm thick. Seeds not seen.

Discussion:
Eschweilera sagotiana is morphologically similar and difficult to separate from E. micrantha. It differs from the latter by its more coriaceous leaves with more salient tertiary venation on the abaxial surface; the presence versus absence of a duct in the petiole; a more robust pedicel; a hypanthium which is truncate directly below the calyx; and a slightly larger flower (usually at least 2.5 cm in diam.).Eschweilera sagotiana also has affinities with E. subglandulosa from which it differs by its less smooth and shiny leaf surface and more cupshaped fruits with a higher calycine ring. In addition, E. sagotiana has a more easterly distribution.Sagot 1104 serves as the type for Eschweilera sagotiana and Lecythis tapuya. Although both represent the same species, their respective types are marked with different collection dates and therefore they probably represent different individuals of the same species.
