Notes

A monophyletic group of species in Anredera corresponds to the previously recognized taxon Tandonia, but a formal recognition of Tandonia would make the remaining Anredera paraphyletic (Eriksson 2007).A

Distribution (General)

Native to the tropical and subtropical Americas and Caribbean. A few species are cultivated as ornamentals worldwide, and have been locally naturalised.

Description

Scandent to trailing vines. Stem usually glabrous, rarely asperous, sometimes producing tubers. Leaves shortly to distinctlv petiolate, not decurrent; leaf blade lanceolate to broadly elliptic, cordate, or obovate, entire, obtuse to acuminate at apex. Inflorescences racemes or panicles with slender to stout axis, shortly to distinctly pedunculate. Bracts lanceolate to triangular. Pedicels slender to stout. Bracteoles subtending flower, distinctly developed, triangular to broadly ovate, free or sometimes connate at base. Flowers shortly to distinctly pedicellate, bisexual or rarely functionally unisexual, chasmogamous, fragrant. Sepals shorter than petals to equalling them in length, rhombic or rounded ovate to elliptic, free from each other, +/- obtuse at apex, occasionally wvith a gibba at base or a dorsal wing (in fruit), at anthesis whitish, yellowish, or reddish, in fruit pale, brownish, or +/- black, +/- dry, thin to rather thick. Petals uniform or outer two patent and inner three erect, ovate to elliptic or obovate, connate only at base, obtuse at apex, at anthesis whitish, yellowvish, or reddish, in fruit pale, brownish, or +/- black, +/- dry, thin to rather thick. Filaments reflexed in bud, connate and fused at base with tepals; anthers dorsifixed, with thecae parallel and free at apex, dehiscent by longitudinal slits. Ovary globose to pyriform; style 1, undivided to 3-parted almost to the base, or styles 3, in fruit with persistent base; stigmas clavate to capitate or 3-lobed, rarely bifid. Fruit globose to pyriform, in cross section rounded, partly surrounded by enlarged stalk at base, surrounded at base or completely enclosed by persistent perianth or parts of it.
