Petals white, 7.5-13 mm long, narrowly triangular, tapering to the apex, with a basal nectariferous claw circumvillous within, ledged above. Androgynophore up to 1.5 mm tall, glabrous below, sulcate, elongated above the node into a tomentellous upper portion 2-3.5 mm tall. Ovary globose, 4-lobed; stigma with 4-5 broad lobes.
