Description
|
Herbaceous vines; stems slender, pubescent, trichomes multicellular, brownish, to 1.5 mm long. Leaves ovate to elliptic, acuminate apically, shallowly cordate, the sinuses open, or frequently the basal lobes imbricate, sparsely strigose on both sides and the margins, discolorous, mostly 5-11 cm long and 2.5-5 cm wide; petioles slender, pubescent, mostly 2-4 cm long. Inflorescences racemiform, ca. 10-flowered, minutely pubescent; peduncles 5-10 mm long; pedicels 1.5-2.5 cm long. Flowers green; calyx lobes lanceolate, glabrate on both sides, ciliate, 4-5 mm long and 2-3 mm wide; corolla rotate, 2-3 cm in diameter, lobes with prom- inent reticulations of darker green, ovate to elliptic, obtuse, 8-15 mm long and 5-9 mm wide, glabrous to weakly strigose within, glabrous outside, a faucal an- nulus present but interrupted, consisting of 5 small mounds of tissue opposite the sinuses, each mound densely puberulent; corona inconspicuous, 5-lobed; gynostegium 1-2 mm high; stigma head yellow or brownish-yellow, broadly pentagonal.

Note
|
Matelea viridiflora must be thought of as intermediate between Matelea and Gonolobus. There appear to be minute anther appendages associated with M. viridiflora, and the fruit ap- pears to fit into the Gonolobus rather than the Matelea group. Until more infor- mation is available, it is better to maintain the present status of the taxon.
