Description. Leaves strap-like, margins entire, gradually increasing in width from the base, margins parallel in the central portion and converging rapidly to an acute apex. Veins dichotomising once, usually at apparently random points between midrib and the margin. Rarely dichotomising and anastomosing again. Mostly 11–22 veins per 10 mm of midrib (but one specimen has c. 50).
