Description

Key Characters:

Growth Form: Habit unknown.

Stems: Stems unknown.

Roots:

Leaves: Leaves simple. Alternate. Blades elliptic, 12–16 cm long, 1.4–2.6 cm wide. Apex acuminate. Base acute, abruptly contracted into a distinct petiole. Upper surfaces glabrous; lower surfaces grayish tomentose. Margins entire. Petioles 5–8 mm long. Stipules absent.

Flowers: Flowers in inflorescences unbranched, 12–15 cm long, pedicels 12–14 mm long; hypanthium hemispherical, ca. 5 mm long. Flowers bisexual (perfect). Calyx 5-lobed, lobes triangular, apex acute to acuminate, sepals connate, tube adnate to ovary. Corolla zygomorphic, dorsally cleft almost to base, the lobes spirally revolute, tube suberect. Stamens 5, alternate with corolla lobes; anthers with apical tufts of white hairs on the lower 2, connate, dithecal, opening by longitudinal slits, coherent but separating after anthesis or connate and forming a tube into which pollen is shed; filaments distinct or connate above, attached to the epigynous nectary disk or to base of corolla, rarely adnate to corolla tube. Ovary inferior, 2-celled, often crowned with an annular nectary disk; ovule placentation axile, or when 1-celled with 2 parietal placentas; stigmas wet or dry, 2-lobed, appressed and nonreceptive as the style grows through the anther tube, pushing out the pollen, after which the stigmas spread apart and become receptive.

Fruit: Fruit unknown. Seeds unknown.

Habitat: Known only from the type specimen (Rémy 298; P); collected in the early 1850s on O'ahu.
