Description:
Species Description - Tree to 10 m; branchlets sulcate, densely and minutely tomentellous, 2 mm thick, glabrescent; terminal bud to 6 mm long, tomentellous. Leaves evenly distributed along branchlets, blade chartaceous, elliptical or lanceolate, ca. 12(-35) x 4(-8) cm, base obtuse, acute or cuneate, apex shortly (to 1 cm) acuminate, glabrous above, densely and microscopically papillose and slightly pubescent, midrib excepted glabrescent, margin flat or subrevolute beneath, lateral nerves 6-12 pairs, arcuately fused at margin; petioles 0.8-2.5 cm long, canaliculate, glabrescent. Panicles axillary, 7-12 cm long, densely and minutely tomentellous, many-flowered. Flowers 2 x 1.5 mm; pedicels 0.5-2(-3) mm long; floral tube not constricted, inside villous or subglabrous (rarely glabrous); tepals erect, (0.7-)1(-1.2) mm long, inside at base laxly strigillose, outer ones ovate, at margin ciliate, inner ones spathulate, at margin fimbriate; stamens included, 1 mm long, those of ser. I and II with depressed, triangular, glabrous anthers and broad, pilose filaments, those of ser. III with glabrous anthers and pilose, biglandulate filaments; staminodes absent; pistil minutely pubescent, 1.5-2 mm long; stigma truncate, minute. Berry ellipsoid, 2.0-2.8 x 1.5-1.8 cm; cupule thick, subhemispherical, outside covered with wart-like spots or ± tuberculate, merging into the thick, woody pedicel.

Discussion:
My interpretation and delimitation of this species differs from that of previous treatments in various respects. First, Kostermans’ inclusion of A. panurensis in A. firmula from southern Brazil is not followed. This is done not only because of the geographical separation of the two species but also because there is a clear morphological differentiation of the flowers, at least in size. Second, I have not been able to distinguish between A. mas and A. panurensis. There are collections with large cupules, berries, and leaves referable to A. mas and collections with smaller cupules, fruits, and leaves which could represent A. panurensis. But in fact, there is no sharp borderline between the two types and the correlation between fruit and leaf size is rather weak. Therefore, I have seen no other way than to unite all material in one polymorphous species. Within this species, some combinations of characters occur again and again. These combinations are described below.Material from Venezuela is characterized by a funnel-shaped cupule with an undulate margin which, when better known, may prove to represent a taxonomic entity worthy of being recognized at the subspecific level.VENEZUELA. Merida: Pueblo del Sur, Bernardi 2316, fl (NY). Barinas: Río Curbati, Bernardi 1811, fr (NY). Apure: San Camillo, Steyermark et al. 101662, fr (NY). Anzoateguí: Río Neveri, NE of Bergantin, Steyermark 61368, fr (F). Amazonas: Rio Pacimoni, above mouth into Casiquiare, Steyermark & Bunting 102464, fl, fr (NY).The following material agrees with A. panurensis except for the smaller outer tepals which may be due to hybridization with A. parviflora. The length of the inflorescence corresponds to that of A. panurensis.BRAZIL. Amazonas: Manaus, Reserva Florestal Ducke, INPA 15179, fl (INPA, M), INPA 15184, fl (NY), INPA 20746, fl (HBG, INPA), INPA 21355, fl, fr (INPA, M), Prance et al. 2114, 2124, fl (HBG, NY); Manaus-Caracaraí Highway, km 148, Bisby P18117, fl (HBG, NY).As to leaf characters, the following specimens seem to be intermediate between A. panurensis and A. rosaeodora. The shape of the leaf resembles the latter species but the texture and slightly revolute margin resemble the former. The wood is said to be exploited, just as is rosewood, for distillation.SURINAM. Paramaribo, Culture Garden, BSS 194, fl (K, NY, U), LBB 9604, fl (U); Tapanahony River Schulz 8167, st (NY, U); Gonini River, Gonggrijp 3711, st (U).FRENCH GUIANA. Montagne de Kaw, Cowan 38780, st (NY, VEN).The specimens Ducke RB19928 and Ducke RB19929 from Juruty Velho, Pará are syntypes of A. rosaeodora var. amazonica Ducke, but since the material is very poor it is questionable whether they represent A. panurensis, A. rosaeodora, or A. burchellii.
