Common name(s): [more details]

English: Ceylon raspberry, hill raspberry, Mysore raspberry

Spanish: frambuesa, mora, mora de Castilla

Habit:  shrub

Description:  "Shrubs; stems up to 20 dm long, tomentulose when young or glabrous and glaucous, covered with stout, hooked prickles 3-7 mm long, their bases usually longitudinally elongated, bark of older stems not shredding.  Leaves pinnately compound, leaflets 5-9, elliptic-ovate to elliptic, 2.5-6 cm long, 2-3 cm wide, the terminal one often broadly ovate, more or less lobed on one side, and up to 5 cm wide, upper surface glabrous, lower surface densely white tomentose, margins serrate, petiolules 0-0.1 cm long, petioles and rachis usually with curved prickles.  Flowers in short, terminal, cymose panicles, densely tomentose and with scattered prickles, pedicels 6-12 mm long; petals rose purple, broadly obovate to suborbicular, ca 4-5 mm long.  Fruit dark red, becoming reddish black, subglobose, ca. 1 cm long, white tomentulose" (Wagner et al., 1999; pp. 1110, 1891).

Habitat/ecology:  "Forest edges, riparian habitats, woodland, disturbed sites.  As other species of the genus, this shrub forms dense and impenetrable thickets due to the arching and intertwining stems.  It displaces native vegetation, impedes regeneration of native shrubs and trees and affects wildlife habitats"  (Weber, 2003; p. 372).

In Hawai‘i, "cultivated and now naturalized" (Wagner et al., 1999; p. 1110). "Smothers smaller plants and impedes passage"  (Motooka et al., 2003).  Moist uplands in the Galápagos Islands (McMullen, 1999; p. 137).

Propagation:  Fruits spread by birds and rodents.

Native range:  India to southeastern Asia, the Philippines and Indonesia (Wagner et al., 1999; p. 1110).

Control: 

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

Chemical:  "Sensitive to drizzle application of triclopyr ester in a crop oil carrier at 1 lb/acre, and to very-low-volume basal bark applications of triclopyr ester at 15% product in a crop oil carrier.  Reportedly tolerant of triclopyr with water as the carrier (Glenn Shishido, DOFAW)"  (Motooka et al., 2003).
