Cauline leaves sessile; blade oblong, base auriculate to amplexicaul, margins entire. Racemes slightly dense. Fruiting pedicels horizontal to divaricate-ascending, often straight, 7–20 mm, (glabrous or sparsely pilose). Flowers: sepals erect, purple, 5–7 × 2–3 mm; petals purple, suborbicular to broadly obovate, 14–17 × 5–9 mm, claw 4–7 mm; median filament pairs 4–7 mm; anthers linear, 3–4 mm; gynophore (slender), 3–6 mm. Fruits erect to ascending, straight, torulose, 5–9 cm × 1–1.2 mm; style cylindrical, (slender), 2–3 mm; stigma 2-lobed. Seeds ca. 1.5 × 0.9 mm.
