2004 Ulmus plurinervia UNGER ; Kovar-Eder et al., p. 66, pl. 6, figs 18–22.
D e s c r i p t i o n. Leaves long-petiolate, petiole slender, often slightly curved; lamina ovate to slender elliptic, asymmetrical, l × w about 38–50 × 15–20 mm, ratio l/w about 2.3–3, base asymmetrically convex on the broader side, rather straight on the smaller side, apex (bluntly) acute; margin simple serrate, teeth dense, directed towards apex, sinus sharp, apex blunt; midvein straight or slightly bent; secondary venation craspedodromous, secondaries regularly spaced, dense, rarely forked, at moderate angles, steeper on the narrower side, mostly corresponding in number to number of teeth (more than 12) except when single secondaries are forked; tertiaries finely and densely polygonate reticulate, hardly distinguishable from higher order veins.
Differing from Cedrelospermum ulmifolium and Ternstroemites pereger see those taxa.
Differing from Zelkova zelkovifolia by long petiole, higher number of smaller and more dense teeth and thus secondaries, and by distinctly asymmetrical base which is convex on the broader side but straight on the narrower side.
