Description:
Species Description - Tree, to 13 m tall. Leafy twigs 1-4.5 cm thick, dark green to brown or white to grayish, sparsely to densely puberulous to hirtellous to subhispid(ulous), also with rather sparse to dense arachnoid indumentum and sparse to dense brown pluricellular hairs. Lamina coriaceous, ca. 25 × 25 cm to 65 × 65 cm, the segments 10-12, (ob)lanceolate, the incisions down to the petiole; apices obtuse to acute to shortly acuminate; upper surface smooth, sparsely hirtellous to strigillose (on the veins); lower surface with ± dense brown pluricellular hairs on the veins or also sparsely puberulous on the main veins, with arachnoid indumentum in the areoles; lateral veins in the free part of the midsegment ca. 20-25, submarginally loop-connected, unbranched; petiole ca. 25-55 cm long, with dense arachnoid indumentum; trichilia separate or fused, the brown indumentum intermixed with rather short whitish to brownish (unicellular) hairs; stipules ca. 15-27 cm long, pink to yellowish, sparsely to densely hirtellous to subsericeous and with dense brown pluricellular hairs outside, glabrous or toward the apex subsericeous inside. Staminate inflorescences in pairs, the peduncle erect, the spikes erect to ± spreading; peduncle 5-6 cm long, hirtellous to puberulous and with dense to rather sparse arachnoid indumentum; spathe ca. 12-13 cm long, pink to greenish, ± densely puberulous to hirtellous outside, glabrous inside; spikes ca. 9-12, ca. 10-12 × 0.5 cm, with stipes 0.2-0.3 mm long and with brown pluricellular hairs; rachis short-hairy. Staminate flowers: perianth tubular, 1.8-2.2 mm long, sparsely and minutely puberulous below the apex, the apex slightly convex; filaments flat; anthers 0.8-1 mm long, appendiculate. Pistillate inflorescences in pairs, erect to pendulous; peduncle 3-6 cm long, hirtellous to puberulous, and with ± dense arachnoid indumentum; spathe ca. 14-15 cm long, pink, densely puberulous to subsericeous outside, glabrous inside; spikes 2-3(-6), ca. 11-12 × 1-1.3 cm, to 23 × 2 cm in fruit, sessile; rachis short-hairy. Pistillate flowers: perianth 1-1.5 mm long, with arachnoid indumentum below the apex outside, also in the lower part of the style channel inside, the apex convex, punctate to muriculate or around the aperture minutely puberulous; style rather short, minutely puberulous; stigma comose. Fruit ellipsoid to oblongoid, ca. 2.5-3 mm long, tuberculate.

Discussion:
This species shows affinities to Cecropia plicata, from which it clearly differs by the incisions of the lamina extending down to the petiole.
