Description

Key Characters:

Growth Form: Subdioecious weakly erect to sprawling softly woody shrubs.

Stems: Stems often swollen at the nodes, terete, 4–angled or –ridged, 2–10 dm long, few–to many–stemmed from the base, forming loose clumps, the primary stems few–branched, weakly ascending to sprawling, internodes 0.3–4.5 cm long, pale green, glabrous below, minutely glandular–puberulent on the upper stems and inflorescence, sometimes glabrate.

Roots: Fibrous root system.

Leaves: Leaves simple. Leaves opposite, often appearing fasciculate on short axillary stems. Blades lanceolate to elliptic–lanceolate, conspicuously falcate and usually slightly twisted, weakly v–shaped in cross section toward the apex and especially toward the base, 3–11 cm long, (0.3–) 0.7–1.2 (–2.4) cm wide. Apex attenuate and often slightly curved. Base leaf bases often connate around the stem, base tapered. Surfaces of young leaves and upper ones sparsely minutely glandular–puberulent, especially on the lower surface, the hairs sessile, 0.05––0.1 mm long, erect, white–opaque. blades; blades thin and membranous. Recurved, becoming more so in age; margins weakly revolute. 3 principal veins, these pale and somewhat translucent, the midvein slightly excentric. Petioles 0–0.5 cm long. Stipules absent.

Flowers: Flowers in inflorescence terminal, with 55–534 flowers, 3–11 cm long, laterally contracted and congested, lateral branches short, the branches and pedicels ascending, puberulent with hairs like those of the leaves; bracts green, linear–subulate, recurved, those of central axis 2–20 mm long, those of branches and flowers 0.5–2 mm long. hermaphroditic flowers occurring occasionally intermixed in staminate inflorescences, numbers varying with site and moisture, similar to staminate flowers except ovary and styles functional. Flowers subdioecious. Calyx of staminate flowers with sepals subequal, 2.5–3.4 mm long, narrowly ovate, yellowish green, yellow toward the base, opaque, reflexed and convex at the base, producing a small transverse bulge, the middle part concave, curved upward and broadly navicular to nearly flat in the distal ⅓, sometimes irregularly inrolled toward the apex, oriented at 90° to 100° angle to the pedicel, sparsely minutely glandular–puberulent, the glands almost sessile, margins scarious, apex obtuse. Calyx of pistillate flowers: sepals subequal, 2.1–2.5 mm long, narrowly ovate, yellowish green, opaque, convex at the base, producing a small transverse bulge, the middle part concave, nearly flat in the distal ½, inrolled at apex, oriented at 90° to 100° angle to the pedicel, sparsely minutely glandular–puberulent, the glands nearly sessile, margins scarious, apex obtuse. Corolla (petals) absent. Staminate flowers: Stamens 10, the filaments dimorphic, the antisepalous whorl 3.5–3.8 mm long, the alternate whorl 3.0 mm long, anthers ca. 0.6 mm long, pale yellow. Pistillate flowers: Stamens 10, vestigial, the filaments subequal, the antisepalous whor Staminate flowers: styles 2–3, greenish yellow, weakly elongating, non–functional. Pistillate flowers: Ovary superior, 1-celled, placentation free-central; styles (2–) 3–4.

Fruit: Capsules 2–2.5 mm long; narrowly ovoid. Seeds relatively few; ca. 0.6 mm long; orbicular–reniform; compressed; the faces depressed; the surface transversely rugose; perisperm starchy; hard or rarely soft; true endosperm absent.

Ploidy: 2n = possibly 60*.

Habitat: In remnant <i>Sapindus oahuensis</i> dry forest now mixed with </i>Leucaena</i>; on steep slopes and exposed ledges.

Elevation Range: 60–305 m.
