Corolla pale yellow or whitish, with a purple center, 2-2.5 cm, midpetaline bands densely pilose. Stamens ca. 9 mm; filaments minutely papillate basally; anthers ovoid-deltoid. Ovary villous. Capsule enclosed by persistent calyx, depressed globose, 8-10 mm in diam., pilose. Seeds dull black, ovoid-trigonous, 4-6 mm, glabrous except for pubescent hilum. Fl. and fr. year round. 2n = 30.
Twining or prostrate perennial herb. Leaf oblong or ovate to broadly ovate, cordate, hastate, cuneate or sometimes truncate at base, dentate or entire, pilose to velvety on both surfaces. Corolla 20-35 mm long. Flowers pale yellow or white, usually with purple or claret centre.

Peduncles 5-100 mm long, pubescent, axillary, 1-flowered or sometimes bearing 2 or 3 flowers in a bracteate cyme; pedicels usually short, up to 3 mm long (in fruit 5 mm); bracteoles oblong or linear-lanceolate, acuminate, 5-17 mm long. Sepals 5, lanceolate to ovate, acute, up to 17 mm long, ± hairy and ciliate, herbaceous; outer ones large, accrescent and nervose in fruit; inner ones smaller. Corolla campanulate to funnel-shaped, 20-35 mm long, pale yellow or white, usually with maroon or purple centre, limb with 5 very short, rounded, emarginate, mucronulate lobes; midpetaline areas polose outside. Stamens 5, included; filaments linear with dilated bade; pollen smooth. Disc annular. Ovary densely hairy with long white hairs, also a few long hairs on basal part of style, 1-locular or imperfectly 2-locular at apex, 4-ovuled; style simple, filiform, included; stigmas 2, ovate-oblong, flattened. Capsule 1-locular, depressed-globose to ± quadrangular, seeds. Seeds 2-4, black, opaque, glabrous except for pubescent hilum, 5-6 mm long.
