Sterile stem up to 19 cm. long, 4-leaved; lower leaves sheath-like, adpressed, the upper leaves lanceolate, to 31 cm. long and 2 cm. broad.. Flowering stem erect, slender to rather stout, leafy along its entire length; leaves 5–8, the lowermost 1–3 sheath-like, obtuse, the remainder ± erect, lanceolate or narrowly lanceolate, acute, up to 6–21 (–31) cm. long and 1–4 cm. broad, the uppermost much smaller.. Inflorescence ± pyramidal, 2–10(–13) cm. long, 2–5 cm. in diameter, densely 10-to many-flowered; bracts spreading, the lower ones reflexed, lanceolate, acute, 7–35 mm. long, hairy inside.. Flowers almost spreading, sessile, pink, deep red, mauve or purple, sometimes with darker markings; ovary 6–8 mm. long.. Sepals and petals projecting forwards, united to one another in their lower half or third and with the lip in their lower third or quarter.. Intermediate sepal narrowly oblong-oblanceolate, rounded, 7.5–21 mm. long, l.5–2(–3) mm. broad; laterals obliquely oblong-elliptical, obtuse, shorter than the intermediate but 2.5–7 mm. broad, several-veined.. Petals similar to intermediate sepal but narrower, like it 3-veined; all tepals pubescent inside at the base.. Lip very convex with a wide mouth, the apex narrowed and erect, 7–16 mm. long.. Spurs short and broad, 1.5–5.5 mm. long, ± 2 mm. in diameter.. Column slightly curved, the slender stalk longer than the fertile part, 5–8 mm. long, glabrous; stigma semi-orbicular, concave, ±1.5 mm. high and 2.5–3.5 mm. broad, rostellum porrect, truncate, shortly and equally toothed in front.
