Tepals greenish yellow to olive green, aging to light green, narrowly rhombic to oblanceolate, 5–9 × 1.3–3 mm, base gradually attenuate to a narrow stalk, not clawed, margins entire, apex acute to acuminate; glands obscure, whitened in age, not nectariferous; stamens 3–4.5 mm; filaments inserted on tepal bases, 0.4 mm from ovary base, slightly dilated basally, barely 1/3 as wide as tepals at insertion point; anthers 0.5 mm; ovary ovoid, glabrous; styles 1–1.5 mm; pedicel spreading to nearly perpendicular, 5.5–11 mm. Capsules elliptic-oblong, 10–18 × 7–10 mm, glabrous. Seeds 7.5–10 × 3.5–4.5 mm (including wings). 2n = 16.
