| D. I. Axelrod 1939 | Leaflet elliptical, slightly asymmetrical, with an obtuse apex and an acute base; 3.1 cm. long and 1.4 cm. wide; petiole 1 mm. long; midrib heavy and slightly curved below, straight above and becoming finer, produced beyond the apex into a fine point; secondaries subopposite, the lower 2 pairs departing at 55° to 65°, looping upward and joining onto the tertiaries of the pair above well within the margin; the upper secondaries departing at 25° to 40° and also looping within the margin to join onto the secondaries above; a thin pair of primary basal nerves extending from near the base well upward and looping inward to join onto the lower pair of secondaries; these fine basal nerves flanked on the outer side by an even thinner pair of nerves, joining to the basal primaries by tertiaries at right angles, forming rectangular areas; the intersecondaries passing outward and soon becoming lost in the tertiaries; tertiaries forming irregular quadrangular and hexagonal areas and also flanking the camptodrome secondaries on the outer side and forming rectangular areas; margin entire; texture medium. |
