Figs 5 , 6 Ab Licania harlingii foliis coriaceis, minoribus 3-7 x 1.5-3.5 (haud 7-12 x 3-7 cm), venis 6-7 (haud 8-11), petiolis 2-3 mm longis (haud 5-6 mm) differt. Description. Tree to 25 m tall, the young branches sparsely puberulous, not conspicuously lenticellate. Leaves with lanceolate stipules to 2 mm long, caducous, adnate to base of petiole; petioles 2-3 mm long, terete, tomentellous when young; lamina elliptic, coriaceous, 3-7 x 1.5-3.5 cm, cuneate at base, acuminate at apex, the acumen 3-6 mm long, glabrous above, densely brown-tomentellous beneath; midrib plane above, prominent beneath; veins 6-7 pairs, plane above, prominulous beneath. Inflorescence of terminal and subterminal panicles of racemes, the rachis and branches yellow-brown tomentose. Bracts and bracteoles lanceolate to triangular, 1-2 mm long, tomentose, caducous. Flowers almost sessile on primary inflorescence branches. Receptacle turbinate, tomentose on exterior, densely tomentose--pilose within, constricted at base to a minute pedicel 0.5 mm long; calyx lobes 5, acute, triangular, tomentose on exterior, sparsely tomentose within. Petals absent. Stamens 5-6, inserted opposite four calyx lobes. Style basal, pubescent for 3/4 of length; ovary rufous tomentose. Fruit pyriform, 2-2.5 x 1 cm, exterior densely rufous-brown tomentose. Figure 5. Photo of the type of Licanis monteagudensis (Monteagudo et al. 5164). Figure 6.

This species falls into subgenus Licania section Licania and it is close to Licania harlingii Prance but differs in the smaller more coriaceous leaves (3-7 x 1.5-3.5 vs 7-12 x 3-7 cm), fewer veins (6-7 vs 8-11) and the shorter leaf acumen. The habitat is noted as primary forest. This is named for Abel Monteagudo, the collector of the types of two of the species described here. Since two of these new species and the recently described Licania condoriensis Prance (2013) from the borders of Peru and Ecuador all belong to subgenus Licania section Licania I have provided a key based mainly on vegetative characters to all species of the section known to occur in Peru. All other species of Licania from Peru fall into other subgenera and sections of Licania of Prance and Sothers (2003a) . They differ from Licania apiknae , Licania condoriensis and Licania monteagudensis in one or more of the following characters: Stamens 10-50, exserted (Subgenus Moquilea ) Petals present Leaf undersurface with a furfuraceous pulverulent pubescence (Section Pulverulenta ) Inflorescence a panicle of cymules (Section Cymosa ) Leaf undersurface glabrous or with a hirsute pubescence (Sections Hymenopus and Hirsuta )
