Description

Key Characters:

Growth Form: Subshrubs ca. 3–6 dm tall.

Stems: Stems often swollen at the nodes, terete (cylindrical), 4–angled or –ridged, probably erect or ascending, branched, glabrous except sometimes in the inflorescence.

Roots: Fibrous root system.

Leaves: Leaves simple. Opposite. Blades narrowly lanceolate, the uppermost linear, 10–18 cm long, 0.8–2 cm wide. Apex attenuate. Base leaf bases often connate around the stem. Blades chartaceous when dry, with only the midvein evident. Margins entire and often slightly revolute or in basal sections with minute antrorse epidermal protuberances or serrulate, at least in the distal half, sometimes the teeth irregularly spaced and inconspicuous. Midvein ± slightly excentric. Petioles 0–0.3 cm long. Stipules absent.

Flowers: Flowers in inflorescence terminal, with 20–150 flowers, ca. 20–27 cm long, diffuse, glabrous or sparsely puberulent; bracts green, oblong-lanceolate to subulate, those of central axis 2–70 mm long, those of branches and flowers 1–2 mm long; pedicels 20–40 mm long, filiform. Flowers apparently bisexual (perfect). Sepals 2–3 mm long, narrowly lanceolate, apparently purple, probably strongly reflexed and convex in the proximal ¼, the distal part concave or shallowly navicular, oriented at 5° to 30° angle to the pedicel, abaxial side glabrous, margins conspicuously scarious, ciliate, apex attenuate. Corolla (petals) absent. Stamens apparently 10; filaments ca. 6–7 mm long; anthers unknown. Ovary superior, 1-celled; ovule placentation free-central; styles 3.

Notes

  • Description digitized by Mercedez
  • Description digitized from the Manual of the Flowering Plants of Hawaii
  • Known only from 4 collections from Auwahi to Kaup0 Gap, East Maui, probably in mesic forest. Last collected in l9l0
  • Schiedeo implexa is closely related to S. nuttollii of O'ahu but differs in having more diffuse inflorescences with capillary pedicels and long, narrow leaves.
