Description:Latin Diagnosis - Arbor circa 10 m alta, ramulis juvenilibus tomentosis mox glabris. Folia alternata petiolata; petiolo 8.0-12.0 mm longo, tomentoso mox glabro, tereti, prope laminam cum glandulis duobus munito; laminae coriaceae, oblongo-ellipticae, 10.0-18.0 mm longae, 5.5-9.0 cm latae, basi rotundatae vel subcordatae, apice in acuminem 2.010.0 mm longum contractae, supra glabrae, subtus cum cavis stomatalis faucis dense lanato-pubescentibus, venulis glabris conspicuis; costa media supra plana, glabra; costis secundariis 12-16 jugis, supra planis, subtus prominentibus glabrescentibus. Stipulae ad 13.0 mm longum, triangulares, naviculares persistentes, coriaceae, tomentosae, cum basi petiolo adnatae. Flores 6.0-7.5 mm longi, sessiles, in paniculis racemosis terminalibus subterminalibusque dispositi, rachi ramisque ferrugineo-tomentosis. Bracteae ad 10.0 mm longum, tomentosae, persistentes saepe cum folio vestigiali adnatae, bracteolae 1.0-3.0 mm longae, oblongae, tomentosae, persistentes. Receptaculum anguste campanulatum, pro genere magnum, extus brunneo-tomentosum, intus tomentosum. Calycis-lobi acuti, utrinque tomentosi. Petala nulla. Stamina 8, unilateralia, staminodiis dentatis opposita; filamenta calycis-lobos breviora, glabra. Ovarium ad basim receptaculi insertum, pilosum. Stylus e basi ovarii ortus, calycis-lobos aequans, lanato-pubescens. Fructus mihi ignoti.

Discussion:This species is known only from the type gathering. It belongs to section Licania, but is most distinct within the genus on account of its large flowers, large navicular stipules, and the leaves with extremely well-developed stomatal cavities. The only other species in section Licania with comparable large flowers is L. couepifolia, which differs in many other characters. The large navicular stipules distinguish it from all other species of Licania. The inflorescence is interesting in that the lower branches have much larger bracteoles subtended by a residual leaf, showing that these bracteoles are morphologically equal to the stipules which they resemble in shape.
