incorrectly designated as a 'neotype'; "the impression in silty sandstone was badly cracked and too fragile to be isolated. Therefore, after clearing the dust from the surface of the leaf, the fossil was photographed under the sunlight using Canon SX110 digital camera. Because the original material was destroyed during the extraction, its figure is used as the type material as per article 9.6 of the International Code of Botanical Nomenclature (Mcneill 2006). The neotype in the form of a high resolution image is deposited in the museum of the Birbal Sahni Institute of Palaeobotany, Lucknow"

Diagnosis
Leaf complete, simple, symmetrical, mesophyll, elliptic; preserved lamina length 12.44 cm, maximum width 6.18 cm near the middle position; apex acute; base symmetrical, obtuse, normal; margin entire; texture, appearing chartaceous; attachment with petiole normal, petiole length 1.52 cm; venation pinnate, eucamptodromous; primary vein moderate in thickness, slightly curved; secondary veins six pairs visible, 0.77–3.59 cm apart, distance decreasing upwards, alternate to sub-opposite, moderately thick, angle of divergence moderate acute (52◦–63◦) (the basal pair of secondaries which is thinner than the mid-vein gives the false impression of basal acrodromous venation), lowermost secondary veins opposite, more acute than middle ones, predominantly uniform but a few secondaries abruptly curved joining super-adjacent secondaries with percurrent tertiary veins; intersecondary veins present, simple; tertiary veins percurrent, simple, convex, oblique in relation to mid-vein, close, angle of origin AA-OA; quaternary veins and further fine features not preserved.
