Description

Species Description - Trees, 3-20 m. Branchlets slender, midway along flush 2-3 mm diam., angular, sparsely strigillose, the surface clearly exposed, dark brown, the hairs reddish brown, ca. 0.1 mm, appressed; terminal buds slender, 1 × 0.3 mm, tan sericeous. Leaves alternate, widely and evenly spaced along current flush; petioles slender, to 1 × 0.2 cm, canaliculate, the indument as on branchlets; laminae chartaceous, plane, elliptic to obovate, 7-20 × 3-8 cm, the base acute, attenuate, the apex acute, acuminate for up to 1.5 cm, the margins flat; upper surface dark green to blackish brown, waxy, the primary to fourth-order veins raised, their prominence decreasing with rank; lower surface sparsely rusty strigillose, the hairs slightly denser on main veins, all vein orders raised, their prominence decreasing with rank; secondary veins 5-7 per side, ± evenly spaced, slightly more distant around midlamina, patent, diverging at 70-85° (more obtusely around midlamina), arcuate to abruptly ascending after midcourse, distal pairs loop-connected; tertiaries laxly reticulating between secondaries. Staminate inflorescences evenly spaced along current flush in the axils of foliage leaves, to 5 cm long with 3 lateral branches, branch orders 2-3, the highest order dichasial, lax, the flowers distant, the axes rusty strigillose, distal branches and pedicels more densely so; bracts and bracteoles caducous by anthesis, ovate, rusty sericeous; pedicels gradually increasing in diameter apically, to 2 mm long, those supporting secondary flowers slightly shorter. Flowers hypocrateriform, ca. 3 mm diam., densely rusty strigillose outside; receptacle infundibuliform, 0.3 × 0.6 mm, slightly constricted below tepals, rusty papillose inside. Tepals chartaceous, ovate to triangular, 1 × 0.6 mm (the inner whorl slightly narrower), spreading to reflexed at anthesis, the inner surface minutely rusty papillose, the indument reduced to a basal triangular patch in the outer whorl but covering surface of inner whorl. Stamens of whorls I and II 0.5 mm tall, sessile, the anthers ovate, 0.3 × 0.3 mm, minutely rusty papillose near base on the abaxial side, otherwise glabrous, the apex apiculate, the connectives prolonged between the 2 locelli, these obliquely hemispherical, introrse-latrorse, the filaments fleshy, slightly broader than anthers, densely rusty papillose; whorl III stamens sessile, 0.6 mm tall, the anthers ovate, equal to those of the outer whorls, erect, locelli 2, extrorse-latrorse, the filaments as broad as anthers, fleshy, columnar, rusty papillose, the basal glands absent; whorl IV wanting; pistillode filiform. Pistillate inflorescence with indument, color, and branching as in staminate plants, the flowers similar in size and shape; stamens sterile, smaller; ovary glabrous, ovoid; style stout, weakly distinguished from ovary; stigma tri-lobed, ca. 0.4 mm diam., minutely papillose. Fruits borne on clav-iform pedicels of up to 1.5 × 1 cm; cupules shallowly hemispherical, thick walled, to 1 × 2 cm, glabrous inside and outside, the margins entire; drupes ovoid, to 3 × 2 cm.

Discussion

Endlicheria mishuyacensis alone in the E. browniana species group combines rusty pubescence and dark brown leaves with patent secondaries and reticulate tertiaries. Sympatric E. dysodantha is superficially similar with dark leaves of similar size, shape, and color, but has barbellate tufts of hairs in the axils of the secondary veins below and scalariform tertiaries.

Distribution

Medium sized trees already fertile at 3 m occurring in nonflooded lowland (100-400 m) forests in western Amazonia. Flowers and fruits have both been collected in all months but January, February, and March.
