    Species Description - Tree to 20 m; branchlets stout, rusty-tomentose, glabrescent, 4-5 mm thick; terminal bud tomentellous, conspicuous, ca. 1.2 cm long. Leaves clustered at end of branchlets, coriaceous, 2.7-3.6 times longer than wide, 15-30 x 6-10 cm, acute towards base, abruptly obtuse, rounded, or cuneate at base, margin (sub-)revolute, acuminate, the acumen 0.5-2 cm long, glabrous, midrib impressed or slightly prominent, nerves impressed above, with prominent midrib and nerves (the latter united by subparallel, more or less prominulous veins), rusty-villous beneath, nerves 10—14 per side, arcuately ascendent and united near margin; petioles 3-4 mm thick, canaliculate, rusty-tomentellous, 0.5-1.2 cm long. Panicles subterminal, many-flowered, rusty-tomentose, to 12 cm long. Flowers campanulate, rusty-tomentose, 2.5 x 2 mm, floral tube constricted below tepals, pilose inside; pedicels 1.5-4 mm long; tepals broadly ovate, equal, ciliate at margin, inside at base pilose, about 1.2 mm long; stamens included, about 1 mm long, the outer ones with broad connectives projecting beyond the small ventral-lateral cells, filaments rusty-hirsute, narrower than anthers, inner stamens with broad, truncate anthers, dorsal cells and pilose, biglandulose filaments narrower than anthers; staminodes stipitiform, small, pilose; pistil pubescent, ca. 1.8 mm long; style slightly longer than ovary; stigma minute, oblique.

  • Discussion

    Black 47-1512 from Tefé had been determined as Aniba permollis by Kostermans (1953) but the presence of a conspicuous, bracteate terminal bud and the nature of the indumentum, place it as A. williamsii.
