More
Leaves opposite, bright red in winter (fide Palmer & Pitman, loc. cit.), sometimes bractlike near the inflorescences; lamina up to 9 x 5 cm., chartaceous, narrowly to broadly elliptic or obovate-elliptic, lepidote (sometimes inconspicuously) otherwise nearly glabrous, often shiny above, apex acute to obtuse or rounded, sometimes shortly mucronate, base cuneate; lateral nerves 4–6 pairs; petiole 2–7 mm. long.
Fruit reddish, 1·3–2 x 1·3–1·9 cm., subcircular to broadly elliptic in outline, lepidote otherwise glabrous to slightly pubescent mainly on the body; apical peg absent or less than 0–5 mm. long, wings up to 8 mm. wide, stipe 4–7 mm. long.
