Gastrodia procera

Robust herb. Stem erect throughout, dark brown, 26–100 cm high, rarely more. Flowers 8–75, erect at first, then drooping, bell-shaped, 20–25 mm long (excluding ovary), cinnamon brown, white towards apices, exterior surface often very rough; subtending bracts about as long as pedicels; pedicel (excluding ovary) 3–10 mm long; ovary obconical. Labellum 14–17 mm long, 5–8 mm wide, lamina with 2 raised, yellow to orange, much crested, widely divergent calli which merge above the lateral lobes and continue, somewhat more elevated, to just below apex. Fruits 10–20 mm long, pale brown. Flowers Dec.–Jan. (where growing with G. sesamoides, its peak flowering time is 3–4 weeks later than that species).
