Description
Latin Diagnosis - Arbor; ramuli novelli minute adpresse puberuli, pilis aureo-brunneis, indumento persistente, demum glabri, pallide cinerascenti-bubalini, tenuiter squamati, elenticellati. Folia congesta, spiraliter disposita, 13.5-30 × 5.8-11.5 cm, elliptica usque late oblanceolata, apice obtusa usque tenuiter et anguste attenuata, basi acuta usque rotundata, coriacea, supra glabra, infra persistente et subtiliter sericea, pilis aureo-brunneis; venatio eucamptodroma; nervis marginalis praesens; costa supra leviter elevata; nervi secundarii 22-27-jugi, paralleli, leviter arcuati, supra valde impressi; nervi intersecundarii nulli; nervi tertiarii numerosi, tunues, obliqui. Petiolus 1.5-2.2 mm longus, non canaliculata, adpresse puberulus. Fasciculi 5-10-flori, axillares et sub foliis dense congesti. Pedicellus 0.5-2 mm longus, sericeus. Flores bisexuales (?). Sepala quatuor, 4.5-5 mm longa, elliptica (duo interiora angustiora), cucullata, apice obtusa, duo exteriora extra adpresse puberula, duo interiora glabra, omnia intus glabra. Corolla late tubularis, ca. 4.5 mm longa; tubus ca. 3 mm longus; lobi quatuor, ca. 1.5 mm longi, late oblongi, apice truncati, glabri, interdum leviter ciliati. Stamina quatuor, medio tubo corollae aflixa; filamenta ca. 2 mm longa, glabra; antherae ca. 1 mm longae, lanceolatae, glabrae. Staminodia quatuor, ca. 1 mm longa, oblonga, glabra. Discus nullus. Ovarium glabrum, quadri-loculare, dense strigosum; stylus post anthesin ca. 2.5 mm longus, glaber; stylicapitulum simplex. Fructus (non visus) 8-10 cm diam.
Species Description - Tree; young shoots minutely appressed puberulous with golden-brown hairs, indumentum persistent, eventually glabrous, pale greyish-buff, thinly scaling, without lenticels. Leaves clustered, spirally arranged, 13.5-30 × 5.8-11.5 cm, elliptic to broadly oblanceolate, apex obtuse to shortly narrowly attenuate, base acute to rounded, coriaceous, glabrous above, persistently finely sericeous below with golden-brown indumentum; venation eucamptodromous, marginal vein present, midrib slightly prominent on the upper surface, secondary veins 22-27 pairs, parallel, slightly arcuate, strongly impressed on the upper surface; intersecondaries absent; tertiaries numerous, fine, oblique. Petiole 1.5-2.2 cm long, not channelled, appressed puberulous. Fascicles 5-10-flowered, axillary and densely clustered below the leaves. Pedicel 0.5-2 mm long, sericeous. Flowers bisexual (?). Sepals four, 4.5-5 mm long, elliptic (inner two narrower), hooded, apex obtuse, outer two appressed puberulous outside, inner two glabrous outside, all glabrous inside. Corolla broadly tubular, ca. 4.5 mm long, tube ca. 3 mm long, lobes four, ca. 1.5 mm long, broadly oblong, apex truncate, glabrous, sometimes slightly ciliate. Stamens four, fixed about halfway up the corolla tube; filaments ca. 2 mm long, glabrous; anthers ca. 1 mm long, lanceolate, glabrous. Staminodes four, ca. 1 mm long, oblong, glabrous. Disk absent. Ovary globose, four-locular, densely strigose; style ca. 2.5 mm long after anthesis, glabrous; style-head simple. Fruit (not seen) 8-10 cm diam. Field characters.
