Description

Key Characters:

Growth Form: Trees or shrubs, 1.5–9 m tall, terrestrial or epiphytic.

Stems: Stems branched repeatedly, spreading, light gray or light brown, glabrous or rarely pubescent, with numerous helically arranged leaf scars near apex, pith solid, latex white, viscous.

Roots:

Leaves: Leaves simple. Alternate. Blades oblong or oblanceolate, 9–24 cm long, 2.5–6.5 cm wide. Apex acuminate, acute, obtuse, or rounded. Base attenuate. Upper surfaces glabrous; lower surfaces glabrous or pubescent on the veins; lamina coriaceous; upper surfaces dark green, glossy; lower surfaces very pale green. Margins callose–crenulate. Petioles 2–7 cm long, glabrous. Stipules absent.

Flowers: Flowers in inflorescences 2(–4)–flowered, glabrous or pubescent; peduncle 1.5–6 cm long, spreading, bibracteate at middle or apex; pedicels 1.5–4 cm long, spreading, bibracteolate at middle or base. Flowers bisexual (perfect), epigynous, zygomorphic, resupinate, protandrous. Hypanthium 1.7–2.2 cm long, 1.1–1.8 cm in diameter, obconic, glabrous, with 10 longitudinal ridges, the dorsal one forming a definite keel. Calyx synsepalous; tube adnate to the ovary, forming a hypanthium, hemispheric, obconic, obovoid, turbinate, or rarely oblong, smooth or with 10 longitudinal furrows, rarely muricate or with 10 longitudinal ridges; lobes 5, valvate, either less than 1⁄2 as long as the corolla, distinct or rarely connate at base, persistent, triangular or deltate, rarely oblong or ovate, firm, green, or as long as the corolla (rarely only ⅔ as long), connate for 1/5–⅘ their length, deciduous, mimicking the corolla in shape, texture, and color. Perianth 5–6.5 cm long, tubular, greenish white sometimes tinged purple or magenta, glabrous; tube 3–4.6 cm long, 0.9–1.8 cm in diameter, curved, narrower at middle than at base; lobes 5, valvate, 1.1–2.2 cm long, 3–7 mm wide, suberect or spreading slight, those of the calyx each with a prominent median longitudinal ridge. Stamens 5, syngenesious, alternate with the corolla lobes, included or slightly exserted, curved; anthers connate, dithecal, opening introrsely by longitudinal slits, purple or rarely greenish white, the 3 dorsal ones a little longer than the 2 ventral ones, the latter with tufts of stiff white trichomes at apex, otherwise glabrous, or sometimes pubescent along the sutures, rarely so on the surfaces, the tube 1.5–1.8 cm long, 4–5 mm in diameter, glabrous or sparsely pubescent; filaments 4–5 cm long, connate above, free from the corolla, magenta or rarely greenish white, glabrous. Pollen tricolporate, prolate, ellipsoidal. Ovary inferior, 2-carpellate, 2-loculed; ovule placentation axile, placentae large; style slender, terete (cylindrical), with a ring of stiff white hairs near apex; stigma 2-lobed, the lobes appressed and non–receptive as the style grows through the anther tube, pushing out pollen, after which the stigmas spread and become receptive.

Fruit: Berries 2.5–3.7 cm long; 1.5–3 cm in diameter; orange; obconic; obovoid; or ellipsoid; with 10 longitudinal ridges; pericarp thick; leathery; placentae juicy or spongy; apex truncate; crowned with a low circular rim and base of style. Seeds numerous; tiny; dark brown or black; minutely foveate–reticulate; shiny; with a straight; short to spatulate dicotyledonous embryo embedded in oily endosperm.

Ploidy:

Habitat: Montane rain forests.

Elevation Range: 550–1760 m.
