Flowers solitary or in small cymes of 3–4, axillary. Bracts and flowers very similar in shape to those of W. stuhlmannii. Bracts thick, 3 mm. long and 3–3.5 mm. wide, ciliate. Sepals 6–7 mm. long and 4–4.5 mm. wide; petals 5–7 mm. long and 2.5–3 mm. wide, obovate-spathulate, rarely with small lateral expansions at the middle. Staminal tube 4–5 mm. long and 2–3 mm. in diameter, thecae 1.5–2 mm. long. Ovary 2.6–4 mm. long; ovules 25–30. Style 0.5–1 mm. long.
