Description.

Tree to 24 m tall, young branches glabrous, not lenticellate. Leaves with small lanceolate, caducous stipules to 2 mm long; petioles 10-13 mm long, sparsely puberulous or tomentellous when young, terete; lamina ovate-elliptic, coriaceous, 5-14 × 3.5-9 cm, rounded to subcuneate at base, acute to apiculate at apex, glabrous and shiny above; lower surface with deeply reticulate venation filled with a rufous pubescence; midrib impressed above, prominent beneath; veins 6-8 pairs, slightly impressed above, prominent beneath; secondary veins prominent and more or less parallel forming a reticulate pattern, tertiary venation flattened forming stomatal crypts. Inflorescence terminal and axillary towards apex of flowering branches, racemose once-branched panicles, the rachis and branches brown-tomentellous. Flowers ca 1.5-2 mm long, sessile on primary branches of inflorescence. Bracts and bracteoles minute, caducous. Receptacle cupuliform, sessile, short-tomentose on exterior, densely tomentose within; calyx lobes 5, acute, tomentose on both surfac es. Petals absent. Stamens 5-6, inserted to one side of ring. Style basal, pubescent for 2/3 of length, included; ovary pilose-tomentose, inserted at base of receptacle. Fruit not seen.

Closest to Licania laxiflora Fritsch a species of the Guianas and Central Amazonia, but differs in the blunt leaf apex, the longer petioles (10-13 mm versus 4-8 mm), the smaller flowers and bracteoles and the more compact inflorescence. This species has been confused with Licania harlingii Prance, but differs from that species in the longer petioles (5-6 mm in Licania harlingii ), the blunter leaf apex, the deeply reticulate leaf venation beneath. It belongs to subgenus Licania section Licania on account of the included stamens and the absence of petals. The name for this species is derived from “Apikna”, the Aguaruna name for it.
