Pedicels patent, 3–5 mm, equal to subtending bract, sparsely glandular-hairy. Flowers: calyx lobes 1.5–2 (–3) mm, apex acute, sparsely glandular-hairy, rarely glabrous; corolla pale blue or pale lilac, rarely white, 2.5–5 mm diam.; stamens 2 mm; style 0.9–2 mm. Capsules slightly compressed in cross-section, obcordiform to globular, 2–3 × 2–3 mm, apex rounded or ± emarginate, sparsely glandular-hairy. Seeds 30–40, ochre, broadly ellipsoid, ± flat, convex on both sides, 0.5–0.6 × 0.4–0.5 mm, thickness and texture unknown. 2n = 54 (Asia).
