D e s c r i p t i o n. Leaves petiolate; lamina elliptic, l × w about 30–34 × 14–18 mm, ratio l/w about 1.7–2.4, base convex to cuneate, apex not preserved; margin entire; venation almost basally acrodromous; midvein and secondaries rather thin; midvein straight; lateral primaries reaching only to about middle of lamina, looping with secondaries near margin; secondaries widely spaced, the first pair originating at a wide distance from lateral primaries; composite intersecondaries thin and short; tertiaries and higher order veins forming polygonal meshes.
Differing from “ Celastrus ” europaea and Daphnogene polymorpha see those taxa.
