Description:
Species Description - Small tree, occasionally to 19 m; branchlets rather slender, 2 mm in diam., sulcate, densely and minutely rusty-tomentellous, becoming glabrous, grey and verruculous. Leaves evenly distributed along branchlets, chartaceous or subcoriaceous, blade lanceolate, obovate-lanceolate, or elliptic, 12-25 x 4-9 cm, 2.5-4 times longer than wide, at base cuneate, angustate, acute or obtuse, at top acute or obtuse and acuminate (acumen to 1.5 cm long), glabrous, lustrous above, dull, yellowish, micropapillate, sparsely and minutely pilose along midrib, rarely also along nerves and veins beneath; midrib and nerves slightly prominent beneath; nerves 8-12 pairs, ascending and fused 2-3 mm from margin; petiole 6-18 mm long, minutely tomentellous, glabrous, narrowly canaliculate. Panicles axillary, few-flowered, 4-8 cm long, minutely rusty-tomentellous. Flowers 2.5 mm long, (sub-)sessile (pedicel 0-0.5 mm long), tube not constricted below tepals, (sub-)glabrous within, throat villous; tepals erect, subglabrous inside, unequal, outer ones ovate, 0.6-1 mm long, inner ones broadly ovate, at margin fimbriate, 0.8-1.2 mm long; stamens erect, those of ser. I and II 0.8 mm long, with broadly triangular, glabrous anthers, medium-sized cells and hirsute filaments narrowed towards the base, of ser. Ill 1 mm long, with glabrous anthers and large cells and hirsute, biglandulose filaments; staminodes absent; pistil 1.4-2 mm long, base excepted minutely, sometimes sparsely pilose, or completely glabrous; stigma minute. Berry ellipsoid, to 3.3 x 2.0 cm; cupule pateriform or subhemispherical, verruculous or slightly tuberculate, to 1.4 x 2 cm.

Discussion:
Aniba fragrans was described by Ducke (1925) as a tree known only from the region of Santarem where it is called “macacoporanga.” Although Ducke recognized its close relationship to A. parviflora, he separated the two species by: the denser tomentum, the larger flowers, the different scent of the wood and bark, and the paler color of the wood of A. fragans. Aniba fragrans may in fact be slightly different from A. parviflora sensu stricto but I included it in the latter species as a chemical race. Kostermans (1938b) merged A. fragrans with A. firmula (=A. panurensis).
