Ecology and distribution
Trop. Afr.
Biology : Terrestrial saprophytic or semi-saprophytic herb, 20-35 cm tall, brownish-yellow, drying almost black, lacking green leaves; flowering stems 1-3, arising ± halfway along a ± vertical cigar-shaped tuber 8 cm long, 1 cm Ø; peduncle with brownish sheaths; raceme c. 7 cm long, densely 10-20-flowered; flowers drooping, sepals brown, petals dull yellow, lip whitish yellow with yellow papillae on mid-lobe, side lobes purple-veined; bracts lanceolate, 9-10 mm long; pedicel 2-3 mm long; ovary 3-5 mm long, swelling before flowers wither; sepals ligulate-lanceolate, 9-13x1,3-2,2 mm; petals oblong-elliptic, 7,5-11x1-2,4 mm; lip 9-10 mm long, 4-4,8 mm wide, 3-lobed in apical half; side lobes rounded-triangular; mid-lobe 4-4,5x3-3,6 mm; spur straight, 2-4 mm long, apex slightly swollen.
Ecology : Brachystegia and mixed woodland, on stony soil; “growing in quantity under Brachystegia spiciformis, Julbernardia globiflora”; locally common as colonies “in which plants may be found at all stages at one time: in bud, flowering and fruiting”; 500-1700 m alt.
  Variable in depth of colour from predominantly pale yellow green to dull brick red and brown (Ball, o.c.: 124).
  According to Ball (l.c.) the plant has a strong decomposing scent.
  Also in Rwanda ?
  The variety auquieriana Geerinck (in Burundi-Zaire, flowering in September) has purplish sepals and spur, the latter 3,5-4 mm long; var. eylesii (throughout the distribution area, flowering in February) has yellowish to greenish sepals and spur, the latter c. 2 mm long. In spite of the differences in time of flowering, we have not retained the varieties and distinct entities.
