Original diagnosis/description

Aralia foliis membranaceis, minutis, ad 3,4 cm. longis et 2,6 cm. latis, petiolulatis, basi attenuatis, trilobatis; lobis distante acute et adpresse-serratis, sinubus angustis, ima basi paullo dilatatis, separatis, triplinervis; nervis lateralibus paullo suprabasiliaribus.

Emended diagnosis

Golovneva (2018: Cretac. Res., 84: 23):
Leaves trilobate, fan-shaped, ovate or rounded in outline, with cuneate, decurrent near the petiole, base, and serrate margin; teeth small, adpressed; apices of lobes acute or rounded; lobe length equal to 1/4–1/2 of blade length; lateral lobes shorter and narrower, usually directed to the top; sinuses between lobes shallow and narrow, with rounded apices; venation palmate; lateral basal veins slightly curved, diverging from the midvein at an angle of 20–35° in 3–5 mm above leaf margin.
