Description Vines, festooning fences and shrubs, glabrous, stems mostly slender, green or purplish; roots tuberous. Leaves alternate, elliptical, slightly succulent, apically acuminate, basally obtuse to cordate, to 6 cm long, the costa with ca. 3 veins alternating on each side, the minor venation obscure; petioles 4-15 mm long. Inflorescences axillary to terminal, erect or somewhat pendant, 3-15 cm long, mostly lax unbranched racemes, the rachis slender, naked for the- first 10 mm, open or appearing somewhat congested in fruit, evenly cylindrical, the flowers mostly blooming at once; pedicels slender, ca. 1 mm long, subtended by a linear bract, the flowers subtended by 2 minute, cucullate, acute often basally connate bracteoles, and by 2 inner, basally accrescent bracteoles which reach more than halfway up the flower bud. Flowers strongly scented, perhaps sometimes uni- sexual, white, calyx 5-parted, the sepals thin, ovate, basally connate; stamens 5, inserted at the base of the calyx lobes, the filaments slender, the anthers oblong, narrow, and curved, basally bifid, dorsifixed; ovary subglobose or ovoid, the stigma short, the styles 3, slightly clavate, entire, emarginate or 2-cleft, papillose. Fruit samaroid, discoid, the 2 inner bracteoles accrescent and enclosing the perianth and sexual parts, forming broad, reticulate, stramineous wings; seed not seen.
Habit Vines
Note Anredera vesicaria may be recognized by its white, fragrant cylindrical ra- cemes of flowers, and winged fruits. The tubers are reportedly of medicinal value in Peru. Probably a native of South America, the species is sparingly but widely cultivated and is naturalized in many tropical areas. It has been collected only once in Panama in spite of intensive efforts in recent years to relocate it.
Distribution known from the Antilles and from other Central American countries.
