Trop. Afr.
Biology : Terrestrial, sometimes lithophytic, herb 60-100 cm tall; tubers subterranean, irregularly subglobose-conical, 2-4x1,8-2,5 cm; leaves 5-6, oblanceolate, grass-like, erect, 40-70x1-3,5 cm, folded; inflorescence peduncle covered by 7 papery sheaths; rachis 4-13 cm long, densely 10-30-flowered; bracts linear-aristate, 8-25 mm long; flowers yellow with yellow or orange or red papillae on lip, occasionally brown or crimson; pedicel and ovary 12-21 mm long; sepals ovate-elliptic, 9-14x4-6 mm; petals obliquely elliptic, 8-12x3-5 mm; lip tongue-shaped, 8-12x4-8 mm, 3-lobed; side lobes porrect; mid-lobe oblong or obovate, denticulate; callus of 2 basal ridges with long papillae over basal 3/4 of mid-lobe; spur conical, 1-3 mm long; fruit pendent, 18 mm long.
Ecology : Loudetia grassland; bushland; Acacia abyssinica wooded grassland; often in the humus of roots of Afrotrilepis pilosa on granitic rocks; Brachystegia woodland; savanna with Daniellia oliveri, Terminalia macroptera, Lophira lanceolata or with Hyparrhenia sp., Loudetia sp., Cyperaceae; dambos; seasonally wet areas; coastal grassland; in sandy soils and rocky areas; 0-2350 m alt.
  The typical yellow-flowered form with red papillae on lip is very common in grassland; colour variants occur in the S part of the Fl. Trop. E. Africa area.
  S. Africa, Swziland.
  Differs from E. milnei by its larger flowers with red lip papillae.
