Peduncle glabrous, terete, with two bracts, the basal one glabrous, tubular, up to 8 mm long, acute, and the apical one more funnelshaped and shorter. Pedicel glabrous, 8 mm long, articulate and slightly widened at tip. Ovary glabrous, claviform, 4 by 1 mm, 6-grooved, at base narrowing into a c. 15 mm long stalk-like part. Flowers with spreading curved sepals. Median sepal glabrous, narrowly elongate-ovate, 20 by 2.5 mm, caudate, acute, 3-nerved, margin slightly wavy. Lateral sepals glabrous, connate at base only, obliquely elongate-ovate, 22 by 3.5 mm, caudate, acute, 3-nerved, margin stronger wavy than of median sepals.
