Characteristics

Plants rather slender, climbing, essentially glabrous throughout, the stems con-spicuously striate. Leaves rather shortly petiolate, simple, basifixed, subtrapezoid, the top saliently and obtusely 2-lobed, occasionally with a smaller central lobe or mucro, the base obtuse to broadly rounded, 1-10 cm. long, 5-10 cm. broad, conspicuously glandular-ocellate; petioles 0.5-3.0 cm. long eglandular; stipules minutely setose. Inflorescences bearing solitary greenish white or yellow flowers upon paired peduncles, the associated tendril basal; peduncles about 1.0-1.5 cm. long, jointed at about the middle or somewhat below; bracts very inconspicuous, subsetaceous. Flowers 3-4 cm. in diameter; sepals ovate-lanceolate, about 1 cm. long, not corniculate; petals oblong-lanceolate, slightly shorter than the sepals; filaments of the corona in 2 series, the outer about as long as the petals. Fruit subglobose, 1-2 cm. in diameter, greenish yellow.
