D e s c r i p t i o n. Leaves or leaflets, (?) subsessile; lamina incomplete, apical part missing, elliptic, l × w about 70–110 × 20–42 mm, base cuneate, slightly convex, minimally asymmetrical; margin entire near base, then simply toothed, teeth tiny, acute, widely spaced; midvein strong, straight; secondaries brochidodromous in untoothed part, semicraspedodromous in toothed area; secondaries much thinner than midvein, widely, regularly spaced, alternate, at medium wide angles, smoothly curved, looping near margin, occasionally forked; exmedial veinlets of secondaries looping along margin, fine branches entering teeth; intersecondaries rare, tertiaries (forked)-percurrent, almost perpendicular to secondaries; higher order veins reticulate.
Differing from Dicotylophyllum sp. T by bigger and broader lamina, smaller and less distinct teeth, and bent secondaries.
Differing from Dicotylophyllum sp. V by the elliptic laminar shape and slightly asymmetrical base.
