Original diagnosis/description

Ein Blatt, dem des A. olmediaefolium Ung. verwandt, jedoch durch den regelmäßig gesägten Rand und die wie bei A. integrifolium stärker nach vorne gebogenen und unter spitzeren Winkeln eingefügten Secundärnerven von demselben abweichend. Die Tertiärnerven sind sehr fein, nicht hervortretend, bilden ein die ansehnlich langen Segmente ausfüllendes aus polygonalen Maschen zusammengesetztes Netz und hervortretende Randschlingen.

Emended diagnosis

Petiolate, very large-sized leaves, lamina obovate (to elliptic), mostly slightly asymmetrical, l × w up to 210 × 70 mm, base cuneate, at utmost base sometimes obtuse, apex acute/acuminate; margin mostly entire near base, then serrate with tiny, widely spaced teeth to more rarely entire; midvein strong, often bent; secondaries thin, eucamptodromous to semicraspedodromous, widely spaced, at moderate to narrow angles, curved, occasion-
ally branched; exmedial veinlets of secondaries or their branches looping near margin, further veinlets running into teeth; single long intersecondaries interspacing with secondaries, tertiaries (forked-)percurrent, almost perpendicular to secondaries, obtuse towards midvein; higher-order veins reticulate.
