Common name(s): [more details]

Chinese: xi zhu xi fan lian

English: corky passionflower, corkystem passionflower, devil's pumpkin, indigo berry, wild passionfruit

French: grain d'encre, grenadille, liane poc-poc, passiflore

Hawaiian: huehue haole

Spanish: uvilla

Habit:  vine

Description:  "Perennial tendrillous vine; glabrous; stems commonly purplish; leaves 3-lobed or entire, 4-8 cm long, if lobed the central lobe largest, acute; petiole 1-2.5 cm long, with 2 opposed glands; flowers solitary in axils; sepals yellow-green; inner coronal fringe purple; petals absent; flower 18-25 mm broad; pedicel 1.5-2.5 cm long; fruit subglobose, purple, nearly 1 cm think; seeds wrinkled, 3-4 mm long" (Stone, 1970; p. 431).

Habitat/ecology:  An aggressive weed. It does best in the subcanopy layers where it smothers shrubs, small trees and the ground layer. In some areas it also smothers the upper canopy layer (C.W. Smith, 1985; p. 197). In Hawai‘i, "naturalized in grassland, shrubland, open dry forest, and diverse mesic forest, and on exposed ridges, 0-610 m"  (Wagner et al., 1999; p. 1014); "smothers tall trees in mesic forests"  (Motooka et al., 2003).  In New Caledonia, "d'introduction paraît-il relativement récente; devenu très répandu et parfois abondant dans la végétation secondaire" (MacKee, 1994; p. 113). In the Galápagos Islands, "among shrubs and rocks, mostly in shady areas, from near sea level to about 615 m" (Wiggins & Porter, 1971; pp. 723-724).

Propagation:  The fruits have many seeds that are dispersed by frugivorous birds.

Native range:  Tropical America.

Comments:  Introduced to Guam sometime after 1945, recorded from Fiji in 1942 (Stone, 1970; p. 431). Locally a problem in Guam and Saipan; more common as an invasive on Tinian.

Control: 

Chemical: "Probably sensitive to hormone type herbicides but may require basal treatments to protect host plants. Young plants susceptible to drizzle applications of glyphosate at 1 lb/acre"  (Motooka et al., 2003).
