Description:
Description - Understory, less frequently, canopy trees, to 30 m tall, usually unbuttressed. Bark nearly smooth, often with vertically disposed lenticels and very shallow cracks, often with maroon cast, the inner bark white to yellowish-white. Leaf blades elliptic, 7.5-15.5(-21) x 2.5-7.5 cm, glabrous, often with abaxial reddish-brown punctae, chartaceous, with (7-) 10-13 pairs of lateral veins; apex acuminate; base acute to obtuse; margins entire; petiole 5-10 mm long. Inflorescences terminal or axillary, unbranched racemes or paniculate once-branched arrangement of racemes, the principal rachis 2-7.5 cm long, slender, 1-2 mm thick, glabrous to puberulous, the pedicel 8-10 mm long. Flowers 2-2.5 cm diam.; calyx with six lobes, the lobes widely to very widely ovate, 2.5-6 x 2-5.5 mm, erect to spreading, imbricate, convex abaxially, flat to concave adaxially, sometimes gibbous at base; petals six, widely obovate, yellow; hood of androecium 10-11 x 10-12 mm, with distinct double coil; staminal ring asymmetric, with 70-80 stamens, the filaments 1-1.2 mm long, not clavate, white, the anthers 0.4 mm long, yellow; hypanthium constricted into well-defined pedicel; ovary 2-locular, each locule with 3-8 basally attached ovules. Fruits small, cup-shaped, the calycine ring inserted slightly above middle, 1.5-2 x 2-3.0 cm (excluding operculum), the pericarp 2-3 mm thick; operculum convex, with slight indication of umbo. Seeds with lateral aril.

Discussion:
According to Bernardi {coll. no. 2135) the hard and heavy wood of this species splits into fine shingles used in local construction.Eschweilera parviflora is characterized by chartaceous leaves often with abaxial punctae; slender rachises of inflorescences, usually 1-2 mm thick; petals and androecial hood yellow; and small, cup-shaped fruits.An exception is the type of E. montana which is said to have white petals and androecia. Nevertheless, this collection matches E. parviflora in other aspects and is maintained here until further collections prove differently.
