Description

Key Characters:

Growth Form: Sprawling shrubs.

Stems: Stems from an enlarged fusiform root, ascending to scandent, 1.5–4 dm long, viscid puberulent to puberulent, especially on younger parts, often swollen at the nodes.

Roots:

Leaves: Leaves simple. Opposite or whorled. Blades slender, recurved, subulate, 6–15 mm long, 0.5–0.8 mm wide. Base leaf bases often connate around the stem. Surfaces puberulent or viscid puberulent especially along margins and toward base. Margins entire. Sessile. Stipules absent.

Flowers: Flowers in narrow, paniculate or sometimes subracemose cymes, puberulent or viscid puberulent throughout. Flowers bisexual (perfect), actinomorphic. Pedicels 3–6 mm long. Calyx usually purple or purple–tinged, 5-toothed, 11–14 mm long, faintly 10–nerved, puberulent, +/- viscid, or sometimes glabrous, the lobes acute, sparsely ciliate, with narrow, scarious, ciliate margins. Corolla of 5 petals; petals greenish white above, maroon below, drying completely maroon, blades 4.5–5.5 mm long, deeply cleft, exserted 3–4 mm beyond calyx, base with a 2-lobed appendage, exserted ca. 3 mm beyond calyx. Stamens included to barely exserted beyond calyx. Ovary superior, 1-celled or incompletely 2–4 celled, on a well–developed stipe that is adnate to the staminal filament bases and petal bases (referred to as a carpophore); styles 3(4–5); Carpophore ca. 5 mm long, enlarging to ca. 7–8 mm long in fruit.

Fruit: Capsules oblong–ovoid; 1–celled throughout; 6.5–8 mm long; dehiscent by 6 or rarely 3 apical teeth or valves. Seeds pale brown; irregularly cuneate;0.4– 0.7 mm long; papillose; the faces somewhat depressed.

Ploidy: 2n = 24*

Habitat: Scattered; restricted to primarily open; dry areas on decomposed lava and ash.

Elevation Range: 900–1,300 (–3,050) m.

Notes

  • 900-1,300 (-3,050) m.
  • Description digitized by Mercedez
  • Description digitized from the Manual of the Flowering Plants of Hawaii
  • Plants from areas other than Kllauea are somewhat intermediate with Silene struthioloides and they should be studied further. Silene hawaiiensis is closely related to and probably derived from S. struthioloides.
