Collected once on Gross Peninsula. Populations usu­ally flower twice during the dry season, once near the onset of the dry season and again in about the middle of the dry season. At the second flowering the plants may also bear fruits from the earlier flowering period. The second flowering is the heavier, with most fruits maturing in the early rainy season, chiefly in July and August.
