Description

Key Characters:

Growth Form: Trees 5–15 m tall; secretory canals present in most parts.

Stems:

Roots:

Leaves: Leaves compound (palmate). Opposite. Leaflets 3–5(–7), coriaceous to chartaceous. midvein, margins, petiolule, and petiole usually tinged purple, petiolule often laterally compressed. Leaflets ovate, elliptic to broadly ovate, or occasionally somewhat obovate, the largest, central one 5-15(-18) cm long, usually 1/2 to sometimes nearly as wide. Apex rounded, obtuse, or occasionally emarginate to caudate-acuminate. Base broadly cuneate to rounded or subtruncate. Margins somewhat thickened, entire to serrate–crenate, the teeth strongly curved upward and in toward the margins, glandular, and usually less than 1 mm long. Veins flat on upper surface (slightly sunken in dried material). Petioles base often broad and sheathing the stem. Petioles 5–12 cm long, petiolules 1–3(–4) cm long, subterete. Stipules absent.

Flowers: Flowers in terminal, erect, oppositely branched panicles of umbellules. Inflorescences up to 20(–24) cm long. Bracts minute, subconnate, persistent, forming an involucel below the umbellules and pseudocalyx below each flower; pedicels 1.5–6 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, petals purple externally at maturity, 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)-carpellate, carpels connate (rarely pseudomonomerous), with as many cells; ovules pendulous, 2 per cell, 1 abortive; styles 2–(–3), 1–2 mm long, distinct or connate up to ca. 1⁄2 their length and then forming a short, conical stylopodium, the distinct arms divergent to spreading.

Fruit: Drupe; 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.

Seeds 1 per pyrene; embryo small.

Ploidy: 2n = 24*

Notes

  • Cheirodendron trigynum is by far the most polymorphic member of the genus. Sherff (1954a) recognized 15 varieties and 3 forms, based primarily on differences in leaflet shape and carpel number, as well as fruit size and the number of flowers per um
