Characteristics

Treelet 5 m. Twigs 1-1.5 mm diameter, ± angular, late glabrescent, hairs shaggy, 0.5 (-1) mm; older twigs yellowish brown, longitudinal cracks and lenticels not apparent. Leaves thinly chartaceous, ± oblong-lanceolate, 8-13 by 1.5-3.5 cm, base short-attenuate, apical part narrowed into long acute-acuminate apex; upper surface dark brown, lower surface grey-brown, glabrescent, hairs scattered, less than 0.1 mm (lens!), subpersistent and stouter on the midrib; not papillose; dots absent; midrib raised above (but in a groove), lateral nerves 14-16 per side, at 60-70° to the midrib, sunken above, lines of interarching and venation distinct on both surfaces; petiole 7-15 by 1-1.5 mm, glabrescent, hairs pilose, to 1 mm; leaf bud 6-12 by 1.5-2 mm, hairs 1 mm. Inflorescences between the leaves, with slender peduncle, paniculate, late glabrescent, hairs woolly, 0.5 mm long or less; male inflorescences not known, but likely resembling those of M. cornutiflora subsp. elegans andM. olivacea; female inflorescences: peduncle 15-25 by 0.5-1 mm, ending in a scar-covered brachyblast up to 5 mm long, with one flower (bud), with or without the initiation of a next bud; flowers with woolly light brown hairs 0.5 mm or less. Female flowers: pedicel 6 by 0.7(-l) mm, bracteole ovate, 0.5-1 by 1 mm, sub-persistent, apical; buds (submature) ovoid-oblong, narrowed in the apical half, 8 by 3 (-3.5) mm, apex subacute, cleft c. 1/8, lobes 0.7(-l) mm long; ovary (from the perianth and immature fruit) ovoid-oblong, 6-6.5 by 2.5 mm, hairs 0.5-1 mm. Fruits solitary, on long slender stalk, presumably pendulous, fusiform, 5-5.5 by 1.5(—2) cm, apex ± beaked, base narrowed into a 5-10 mm long pseudostalk, hairs dense, yellow-rusty, pilose, 0.2-0.4 mm and stouter straight hairs towards the apex and at the base of the pseudostalk; pericarp 1 mm thick; seeds not seen but presumably (ellipsoid-)oblong, 3-3.5 cm; fruiting pedicel 7-9 mm long, pubescent, with the (sub)persistent bracteole 1-2 mm below the apex.
