Lamina fere ad petiolum 15-partita; segmenta oblanceolata, 7-25 cm longa, 2-4.5 cm lata, plerumque obtusa, pagina superiore scabridula, inferiore arachnoideo-tomentosa, ad venas albo-puberula vel -hirtella; venae secundariae circ. 20—40-jugae, maxime 0.5 cm inter se remotae; petiolus arachnoideo-tomentellus atque etiam hirtellus, sed basi apiceque hirsutus vel hispidus; pulvinus pilis brunneis pluricellularibus, longioribus albis unicellularibus, obsitus. Inflorescentiae pistillatae pedunculo 6-7 cm longo; spicae 4, 8-9 cm longae.
Tree up to 25-30 m tall. Leafy twigs hispid to hispidulous to scabreus by mainly uncinate hairs of different length. Leaves subrotundate to broadly ovate, 15 (or more than 15?) -parted to 0.5-1 cm from the petiole, segments oblanceolate, 7-25 cm long, 2-4.5 cm broad, mostly obtuse, sometimes subacute to subacuminate, above scabridulous by short rigid hairs of different length, sparsely intermixed with longer weaker hairs and brown pluricellular hairs, beneath arachnoid-tomentose, this indument disappearing from the main veins with age, on the veins whitish puberulous to hirtellous, the hairs distinctly different in length, the longer ones mostly uncinate; c. 20-40 pairs of secondary veins, at most 0.5 cm from each other; petioles 35-47 cm long, arachnoidtomentellous and sparsely to rather densely hirtellous, but hirsute to hispid at the upper and the lower end; pulvinus with brown pluricellular hairs and longer white unicellular hairs.
