Ecology and distribution
Trop. Afr.
Biology : Terrestrial semisaprophytic herb 10-83 cm tall; with underground whitish cigar-shaped tubers set vertically in ground, 10-12 cm long, c. 1 cm Ø, of many nodes and with scale-like bracts; leaves 2-7, vestigial, linear, acuminate, 2-13x c. 0,2 cm, purplish; inflorescences 1-3, produced before leaves or with young leaves; peduncle wiry, red-green to purple with 2 basal sheaths and 1-2 sterile bracts above; rachis 8-25 cm long; bracts lanceolate, 3-9 mm long; flowers spreading, green tinged purple (sepals), green purple-veined (petals), and greenish yellow with purple veins (lip); pedicel and ovary 10-16 mm long, arched; sepals erect, linear, parallel to each other, 15-32x1-2 mm; petals porrect, narrowly elliptic, 10-16x2,5-4 mm; lip 10-14 mm long, 6-10 mm wide, 3-lobed, with callus of 3 ridges, papillate in 3-5 lines on mid-lobe; side lobes rounded; mid-lobe transversely elliptic, 8-11 mm long; spur conical, c. 2 mm long, slightly incurved; fruit pendent, 25-27 mm long.
Ecology : Brachystegia woodland in dryish areas, often in burnt places; miombo and mixed deciduous woodland; coastal forest and bushveld; on granite outcrops, wooded kopjes, rocky hillslopes and escarpments; usually in stony or sandy soil; “in rich patch of black humus over boulders under Brachystegia tamarinoides [B. glaucescens]” (Ball, o.c.: 138); cupriferous and manganiferous hills; gallery forest; 5-1400 m alt.
  Very variable in stature and in flower size, colour and length of erect tepals and size of callus on lip. The variation is considerable even within one colony.
  S. Africa (close to S Mozambique border).
  Easily recognized by its long narrow erect sepals.
South. Afr.
