Diagnosis

Leaf simple, symmetrical, ovate, preserved size 8.0 x 5.8 cm; apex acute to nearly attenuate; base obtuse; margin slightly lobed; texture thick chartaceous; petiole 1.0 cm long, normal; venation pinnate, basal acrodromous, imperfect, primary vein (1°) three, one mid and two lateral primaries arise at the base. Mid primary stout, almost straight, lateral primaries curved upward and give off secondary veins towards the margin; secondary veins (2°) arise from both mid and lateral primaries at moderately acute angle of divergence, seemingly unbranched, alternate, uniformly curved up; tertiary veins (3°) fine, angle of origin usually RR, percurrent, straight to sinuous, branched, oblique to right angle in relation to midvein, predominantly alternate, close to nearly distant.
