- Diagnosis
- Leaf or pinna fragment, 19 mm long and 9-10 mm wide, without preserved apex. Limb coriaceous with parallel edges, and transverse folds. Midrib 1 mm wide, longitudinally wrinkeled with small protuberances. Secondary veins prominently rising at right angles to the rachis, slightly decurrent near the lower part of the leaf, more oblique, simple or forked once in the first third of the half-limb width. Density: 43-52 veins per 10 mm in lateral edges. Epiderm fragment consisting of a net of small polyhedric cells with straight walls and some larger inconspicuous elements (5-6 μm) possibly corresponding to primitive stomata. Thicker-walled cells (2 mm) might have been hair bases.
