Pl. 10, Fig. 9–10
Incomplete leaf and fragments palmately 3-lobed, 24 to 67 mm long and 27 to 81 mm wide, medial and lateral lobes widely oblong to triangular, apices shortly attenuate, base cordate with petiole up to 12 mm long, margin entire, sinus acute, widely opened, venation basal actinodromous, primary veins strong, moderate, secondary veins thinner, alternate, looping, tertiary veins alternate to opposite percurrent, curved to sinuous, venation of the higher orders regular polygonal reticulate, areolation well developed, 3- to 4-sided.
Maple foliage characterized by such a trilobate form with almost entire lobes was revised by Walther (1972) who proposed a new concept for A. integrilobum and we adhere to his concept. The leaf figured on pl. 10, fig. 10 may also resemble Trichosanthes LINNAEUS ( Kvaček et al. 2008, pl. 9, fig. 13), however without cuticles the assignment is doubtful.
