Basal leaves long-petiolate; lamina linear, 9–16 cm long, c. 5 mm wide, apex very acute, base slightly widened to broad-cuneate, lower surface rather striate, not papillose; stem leaves to 10 cm long, 3–4 mm wide, shortly petiolate.
Flower whorls distant, with subtending leaf many times longer than whorl, flowers numerous per whorl.
Fruiting valves 2.5–3.5 mm long, c. 1.5 mm wide, with 1 (or 2) teeth on each side. Fruiting pedicels 1–11/2 times as long as valves, articulate near base.
