Description

Key Characters:

Growth Form: Dioecious shrubs, 3–6 dm tall.

Stems: Stems often swollen at the nodes, terete (cylindrical), 4–angled or –ridged, erect or strongly ascending, glabrous, intemodes 0.5–2.5 cm long, green to greenish purple.

Roots: Fibrous root system.

Leaves: Leaves simple. Opposite. Blades elliptic–oblanceolate, elliptic, or linear, (2–) 3–5 (–6) cm long, (0.2–) 0.5–1.5 cm wide. Apex acute to mucronate. Base leaf bases often connate around the stem, base attenuated to a winged petiole 0-0.6 cm long. Surfaces yellowish green; blades coriaceous. Margins entire, somewhat thickened and weakly revolute. Only the midvein evident. Petiolate, weakly to conspicuously connate around the stem. Stipules absent.

Flowers: Flowers in inflorescence terminal, with 15–138 flowers, 4–15 cm long, congested, especially laterally, the staminate inflorescences often less congested and broader than the pistillate inflorescences; bracts of central axis 2–15 mm long, those of branches and flowers 1–1.8 mm long, green to purple, linear to subulate; pedicels (1–) 3–7 (–10) mm long, quadrangular and somewhat flattened. Flowers unisexual and plants dioecious. Calyx of staminate flowers with sepals 2.2–2.7 mm long, narrowly ovate, broadly and shallowly navicular, oriented at 100° to 130° angle to the pedicel, green or tinged purple toward the apex, opaque, reflexed and convex at the base, producing a small transverse bulge, glabrous, margins scarious, entire, glabrous, apex obtuse. Calyx of pistillate flowers: sepals 2.1–2.3 mm long, narrowly ovate, green or tinged purple toward the apex, opaque, reflexed and convex at the base, producing a small transverse bulge, broadly and shallowly navicular, oriented at 100° to 130° angle to the pedicel, margins scarious, entire, glabrous, apex obtuse. Corolla (petals) absent. Staminate flowers: Stamens 10, sometimes 1–few weakly developed or with shorter filaments, the filaments slightly dimorphic, the antisepalous whorl 3.1–4 mm long, the alternate whorl 2.9–3.6 mm long; anthers 0.7-0.9 mm long, yellow. Pistillate flowers: Stamens 10, vestigial; filaments unequal, 0.7–0.9 mm long; anthers 0.3-0.4 mm long, yellow, not producing pollen. Ovary superior (pistillate flowers), 1-celled; ovule placentation free-central; styles 3–4. Staminate flowers: styles 3–4, green, short and non–functional, becoming shrivelled.

Fruit: Capsules 2–3.5 mm long; narrowly ovoid. Seeds relatively few; 0.6–0.8 mm long; reniform; compressed; the surface papillose; papillae of the margins larger than those of the faces; perisperm starchy; hard or rarely soft; true endosperm absent.

Ploidy: 2n = possibly 56*

Habitat: Scattered in dry forest to diverse mesic forest; often on cliffs.

Elevation Range: (180–)300–830 m.

  • Several other closely related species grow in the Wai'anae Mountains, yet apparently none occur with Schiedea ligustrina. lt is elevationally separated from S. kealiae and geographically isolated from S. haokeri and S. mannii. Sherff (1950b) reported a hybrid between S. Iigustrina and S. hooken, but we have not seen the specimen cited (Degener 20619). There appears to be no other evidence to support the hypothesis that hybrids occu
