Leaves ovate or ovate-oblong, 2-8 by 1½-5 cm, more or less cordate or rounded to truncate at the base, mostly acuminate and mucronulate at the apex, or sometimes acute to obtuse, glabrous or shortly pilose and glabrescent above and beneath; lateral nerves 5-8 on either side of the midrib, arcuately connected near the margin; petiole slender, 1-6 cm long, finely pilose. Peduncles variable in length, a few mm to several cm, more or less pubescent. Flowers in a loose to very dense few-to many-flowered umbelliform cyme. Pedicels filiform, pubescent, 3-6 mm, or longer in fruit. Bracts small, subulate. Sepals pilose or nearly glabrous, unequal; 3 outer ones, of which the third is often more or less oblique, ovate-lanceolate to ovate, 5-7 mm long, attenuate towards the base, acuminate to long-acuminate at the apex, with a more or less waved acumen, herbaceous, or the third one with a scarious margin at one side; 2 inner ones shorter, 3-4½ mm long, with a broad-ovate to orbicular basal part with scarious margins, acuminate at the apex. Corolla funnel-shaped, 8-10 mm long, lilac, pale blue, pale pink, often paler to white at the base, or entirely white, 5-lobed, glabrous, or with a few hairs at the mucronulate top of the lobes. Filaments subequal, pubescent at their broadened base. Ovary glabrous. Stigmas filiform. Capsule 3-4 mm in diam., brown, 8-valved, the valves lanceolate, acute. Seeds 4 or less, 1½-2 mm long, brownish yellow to purplish black, minutely verrucose, glabrous, the angles with a very narrow scarious wing.
