Flowers: tepals white to pale blue, bases yellow; outer tepals 7–12.7 mm, apex rounded to emarginate, aristate; filaments connate ± entirely, stipitate-glandular basally; ovary similar in color to foliage. Capsules light to dark-brown, globose, 3–5 mm; pedicel spreading to ascending. Seeds globose to obconic, lacking obvious depression, 0.5–1 mm, granular to rugulose. 2n = 32.
