Growth Form: Trees or shrubs 2–7 m tall; secretory canals present in most parts.

Stems:

Roots:

Leaves: Leaves compound (palmate). Opposite. Leaflets 3, very broadly ovate to depressed–ovate or subreniform, 3–6 cm long and usually wider. Apex acute to nearly truncate, apiculate. Base truncate to obtuse. Blades thin, coriaceous, chartaceous when dry. midvein, margins, petiolule, and petiole usually tinged purple, petiolule often laterally compressed. Margins caudate–dentate, almost spiny in appearance, the 3–8 teeth per side pointing out, with an upcurved tip, more than 1 mm long. Veins not raised on upper surface. Petioles base often broad and sheathing the stem. Petioles 5.5–8 cm long. Petiolules of leaflets 3–4.5 cm long, laterally compressed. Stipules absent.

Flowers: Flowers in terminal, erect, oppositely branched panicles of umbellules. Inflorescences 5–9.5 cm long. Bracts minute, subconnate, persistent, forming an involucel below the umbellules and pseudocalyx below each flower; pedicels jointed below the ovary. Pedicels 2–5 mm long. Flowers bisexual (perfect) and functionally staminate (the plants andromonoecious). Calyx of 5 short, basally connate teeth. Corolla of 5(6) petals, buds dark purple, purple externally, greenish within, valvate, caducous, triangular to ovate or oblong, apex inflexed. Stamens usually as many as and alternate with the petals, sometimes numerous, distinct, inserted at the edge of the epigynous nectary disk; 5, pale yellow, spreading. Ovary inferior, (2)3–4(5)-carpellate, carpels connate (rarely pseudomonomerous), with as many cells; ovules pendulous, 2 per cell, 1 abortive; styles as many as carpels, 1–1.5 mm long, connate to form a blunt, conical stylopodium surmounted by the circular stigmas.

Fruit: Drupes green; ripening dark purple; exocarp fleshy; globose; or laterally compressed and orbicular or oblate to ovoid or obovoid; 3–7.5 mm long; pyrenes cartilaginous; laterally compressed; as many as styles.

Notes

  • Apparently quite rare. Cheirodendron dominii has leaves very similar to those of C. fauriei and an ovary and fruit like those of C. platyphyllum subsp. kauaiense. Nevertheless, while all 3 taxa are restricted to Kaua‘i, C. dominii<
