Between two and fifteen or more yellowish green flowers with reddish brown streaks and blotches, 25–35 mm (0.98–1.4 in) wide are borne on a flowering stem 200–300 mm (8–10 in) tall. The sepals and petals are 12–16 mm (0.5–0.6 in) long and 6–8 mm (0.2–0.3 in) wide. The column is greenish near its base then cream or whitish, 6–9 mm (0.2–0.4 in) long and 4–6 mm (0.16–0.24 in) wide and has widely fringed wings.
