Flowers: perianth bristles equaling or slightly longer than perianth stipes, retrorsely barbellate; perianth blades ovate, as long as claws, 2–2.5 mm, base thinner, 3-ribbed, apex compressed-conic, apiculate; anthers linear-oblong, 2 mm. Achenes: body angles pale, wirelike, faces lustrous red-brown or chestnut brown, 1 mm; beak narrow, linear, distally papillate or scabridulous. 2n = 46.
