Description:  "Erect to trailing shrub up to 2 m or more in height.  Stems pilose, sparsely covered with prickles 1-4 mm long.  Leaves alternate, pinnately compound, 7-18 cm long, with 3-7 leaflets, leaflet blades ovate to lanceolate, 1.5-8 x 0.8-3.5 cm, acuminate to acute at the apex, rounded to truncate at the base; surfaces pilose to nearly glabrous; margins doubly serrate; stipules filiform, 6-10 mm long.  Inflorescence mostly of solitary, terminal or axillary flowers on a pedicel 0.5-3 cm long.  Calyx of 5 lanceolate sepals 1.4-2.5 cm long, tomentose, apex long-attenuate.  Corolla of 5 white, obovate petals 1-2 cm long.  Stamens many, free.  Ovaries many.  Fruit a subglobose, red, multiple fruit 2-3.5 cm long, easily detaching from the receptacle" (Whistler, 1995; p. 123).

"Shrubs or subshrubs; stems erect, arching, or trailing, 10-20 dm long, moderately to sparsely pilose, sparsely covered with recurved prickles 1-4 mm long with elongate bases.  Leaves pinnately compound, leaflets 7 or sometimes only 5 in upper leaves, broadly lanceolate, 1.5-8 cm long, (0.6-) 1-3 cm wide, the terminal one slightly larger, sparsely pilose to glabrate and also sometimes glandular-dotted, margins doubly serrate, petiolules 0.1-0.3 cm long, rachis, petiolules, and petioles pilose, rachis and petioles also usually covered with small recurved prickles, stipules filiform, 0.6-0.8 cm long.  Flowers solitary or sometimes 2-3, terminal or axillary; sepals lanceolate, 8-15 mm long, both surfaces finely tomentose, apex long-attenuate; petals white, obovate, 10-20 mm long.  Fruit red at maturity, subglobose, 2-3.5 cm long, easily deciduous from the receptacle"  (Wagner et al., 1999; p. 1110).

Habitat/ecology:  Invades understory of moist forests. Grows to 2,200 m elevation in Tahiti (Meyer, 2000; p. 93). In Hawai‘i, "a common weed in disturbed mesic to wet forest, 60-1,730 m" (Wagner et al., 1999; p. 1110). "A nuisance in pastures and natural areas, where it displaces desirable plants and interferes with passage and use of the land"  (Motooka et al., 2003).  In New Caledonia, "cultivé à Koé en 1883; maintenant très commun près des pistes forestières sur schistes" (MacKee, 1994; p. 122).

Propagation:  Fruits spread by birds and rodents.

Native range:  Asia, Australia.

Comments:  Very invasive in French Polynesia (Meyer, 2000; p. 93).

Control: 

Physical: Isolated plants may be grubbed out, but any remaining roots will sprout.

Chemical:  "Sensitive to triclopyr ester in water and very sensitive to triclopyr ester in a crop oil carrier, each applied by the drizzle method at 1 lb/acre.  HAVO staff reported control with foliar application of either glyphosate at 1% product or triclopyr ester at 1% product in water (Chris Zimmer, HAVO)"  (Motooka et al., 2003).

Additional information:  Information from the book "Weeds of Hawaii‘s Pastures and Natural Areas; An Identification and Management Guide" (Motooka et al., 2003). (PDF format).
