- Diagnosis
- Leaves ovate to ovate-lanceolate, narrowing abruptly to an obtusely cuneate or slightly cordate base, the tip rather obtusely acuminate; length from 3.6 to 6.9 cm.; width from 1.8 to 2.8 cm.; average dimensions 2.5 by 4.5 cm. (see plate 8, fig. 12) ; petiole apparently short and stout, rarely well preserved; midrib strong, straight to slightly curved; 8 to 12 pairs of strong secondaries, sub-opposite to alternate, diverging from the midrib at an angle as high as 90° near the base to 50° or 60° near the apex, and always terminating in the marginal teeth; tertiary venation distinct in a few specimens, forming an irregular network between the basal secondaries to a more regular, percurrent system near the apex; margin regularly dentate, the teeth large, bluntly tipped and pointing upward and slightly outward; texture coriaceous, as evidenced by the curled condition of several specimens.
