Stems 3–12 dm, sparsely hirsute proximally, glabrous distally. Cauline leaves: blade conduplicate distally, margins entire, surfaces glabrous. Racemes not secund; rachis straight. Fruiting pedicels 4–8 mm, glabrous. Flowers: sepals greenish white, white, or pale-yellow, 7–11 mm, glabrous; petals white (with light-brown or purplish veins), 11–17 mm; adaxial filaments 8–10 mm. Fruits divaricate to ascending, straight; valves glabrous. 2n = 28.
