Rather coarse climbers, more or less densely pilose to glabrate throughout. Leaves petiolate, basifixed, broadly 3-lobed to somewhat above the middle, the central lobe much stronger, usually inconspicuously serrulate toward the cordate base, 7-15 cm. long, 5-13 cm. broad; petioles 2-5 cm. long, with 2 to several pairs of slender stipitate glands; stipules conspicuously foliaceous, ovate-subreniform, deeply amplexicaul, 1.5-3.5 cm. long, glandular-denticulate to subentire. In-florescences solitary, bearing a single white and purple flower; peduncle 4-6 cm. long, jointed directly below the flower; bracts rather narrowly lanceolate, 1-2 cm. long, foliaceous, with rather few glandular denticulations to entire. Flowers about 6 cm. in diameter; sepals narrowly oblong, 2-3 cm. long, corniculate; petals linear-oblong, about equaling the sepals; filaments of the corona in several series, the outermost about half as long as the petals. Fruits broadly ovoid, 4-6 cm. long.
Climbing into trees and shrubs on the edges of rain forest, often forming dense mats when growing in more open, secondary formations; at elevations up to 2,000 metres.
Can be grown by cuttings or seedlings. Seeds needs soaking.
