Habit:  shrub

Description:  "Scandent epiphytic glabrous shrub, 1-2 (-3) m high.  Branches terete to subquadrangular, not winged, 4-5 cm in diameter at base; nodes setose, the bristles coarse, yellowish-brown, persistent.  Leaves ternate or quaternate, occasionally opposite near the base, shortly petiolate; petioles stout, 5 mm long or less; blades coriaceous, elliptic-oblong to oblong-lanceolate, 15-22 (-26) cm long, 8-10 (-14) cm wide; apices acute to shortly acuminate; bases shortly attenuate, 5- to 7-plinerved; nerves faintly distinct adaxially, absent abaxially; transverse veins faintly visible on both surfaces.  Inflorescences terminal or axillary, many-flowered, pendant panicles, up to 25 cm long; peduncles 8-10 cm long; the branches in whorls of 4; bracts elliptic-ovate, acuminate at tip, 15-20 (-30) mm long, 5-10 mm wide, persistent; bracteoles minute, subulate, 1 mm long, persistent; pedicels slender, 4-5 mm long.  Flowers 4-merous.  Hypanthia campanulate, 4 mm long, 3 mm wide, pink or purple, denticulate.  Petals obliquely ovate, 7 mm long, 5 mm wide, pink.  Stamens equal; filaments flattened, 4 mm long; anthers dark pink, curved, 5 mm long.  Fruits subglobose, 5-7 mm in diameter, pink to purplish to bluish-black when ripe; stalks terete, 5-7 mm long" (Regalado, 1995).

"Shrub to 8' tall, with square stems, opposite 6-15" leathery leaves lacking stalks, 1/2" bracts below the flower clusters, 1" pink flowers, and 1/4" purple-black fruits with a white tip" (Hawaii's Most Invasive Horticultural Plants).

Habitat/ecology:  Moist and wet forests at low elevations (Hawaii's Most Invasive Horticultural Plants). In the Philippines, "in mossy forest at 700-1000 m altitude" (Regalado, 1995).

Propagation:  "The small dark fruit is eaten by birds, containing many dozens of small seed per fruit. Dispersal capabilities are probably comparable to Miconia [calvescens] and 100,000 of seeds are produced per flowering event." (O‘ahu Invasive Species Committee)

Native range:  Philippines (Luzon) (GRIN).
