Inflorescences axillary, flowers 1- or 2 per peduncle, held usually above leaf level; peduncles longer than leaves, antrorse-hairy; pedicels erect or reflexed in fruit (but capsules erect). Sepals oblong, 3–4 mm long, often ciliate; petals 7–10 mm long, yellow. Capsule 13–24 mm long, 3–4 mm diam., moderate to broad cylindrical or narrow ellipsoid, occasionally thickened in middle, usually densely retrorse-hairy, occasionally also with longer patent septate hairs; seeds 1.7–2.2 mm long, transversely ribbed, grooves U-shaped, ribs without greyish or whitish lines or blotches.
