Flowers are arranged in clusters 3 to 5 cm (1.2 to 2 in) long at the ends of the branches. The flower has 5 green, oval sepals, which are about 3 mm (0.1 in) long, no petals; 5 nectaries, which are 1 to 1.3 mm (0.04 to 0.05 in) long; and 10 stamens.

This species differs from other species of the genus on East Maui by its crowded, hairless inflorescence composed of bisexual flowers.
