Twigs solid, slender, 3 mm diam., terete, smooth, finely pubescent. Stipules elliptic, 5 mm, papery, pubescent, erect, very soon caducous. Leaves: petioles 45 cm, slender, terete, finely pubescent, sometimes weakly kneed at top; blades rhombic-ovate, very occasionally with 2 lateral cusps or small lobes, 714(17) by 410(15) cm, thinly leathery, base truncate to very broadly rounded, often under 1 mm peltate, occasionally with inconspicuous glands on nerves near petiole insertion, margin with small glandular teeth, apex acute or acuminate, drying khaki below and often dark brown above, below granular glandular and velvety with short spreading white hairs on all nerves including the raised reticulum, with 3 main and several minor nerves at petiole insertion, surface above with white hairs (caducous except on nerves) arising from small persistent pustules. Inflorescences diffuse narrow racemes to 6 cm; branches sparse to 15 mm; peduncle short, 1 cm; axes slender, main axis terete, finely pubescent, lower branches alternate; bracts elliptic, 5 mm, dentate, leaf-like, pubescent, with pinnate nervation, sometimes stalked, soon caducous; flower clusters in groups, smaller than bracteoles, overlapping, branches developing through flower clusters (as M. tanarius); bracteoles persistent, ovate, strongly concave, to 4 by 2mm, apex acute, pectinate, pubescent on both sides, nerved. Staminate flowers c. 14 per cluster, maturing in sequence; pedicel 0.5 mm, tomentose; sepals united, elliptic, tomentose; stamens 2, strongly exserted, 0.5 mm long, anthers 4-locular.
