Basal leaves (often withered by fruiting); blade oblanceolate, 2–10 cm × (0.2–)0.5–1.5(–2.4) mm, base attenuate, margins dentate, apex acute. Cauline leaves (distal) sessile; blade margins entire or denticulate. Racemes considerably elongated in fruit. Fruiting pedicels horizontal to divaricate, slender, narrower than fruit, 5–16(–25) mm.

Fruits widely spreading or divaricate, narrowly linear, usually straight, rarely curved upward, not torulose, (3–)5–12(–14) cm × 1.2–2.7 mm, 4-angled, strongly (longitudinally) 4-striped; valves with prominent midvein and replum, densely pubescent outside, trichomes 2-rayed between midvein and replum, glabrous inside; ovules 72–120 per ovary; style cylindrical, slender, 1–4 mm, sparsely pubescent; stigma slightly 2-lobed, lobes as long as wide.
