Ecology and distribution
Trop. Afr.
Biology : Terrestrial herb 30-110 cm tall; tubers subterranean, fleshy, irregularly cylindrical, depressed, 3,5-5x1,3-2,5 cm, in a chain; leaves 4-7 in a fan, partly developed at anthesis, linear, 21-38x0,3-1 cm, glaucous-green, folded, slightly succulent; inflorescences 1-2, 45-110 cm tall, peduncle with few scales; rachis 7-23 cm long, laxly 10-20-flowered; flowers fleshy, nodding, purplish (sepals) and yellow (petals, lip) with red veins, lip mid-lobe purple-edged; bracts linear, 4-15 mm long; pedicel and ovary 10-20 mm long; sepals reflexed, oblong, 7-11x3,5-6 mm; petals spreading, twice as large as sepals; lip 3-lobed, 14-16 mm long, 19-21 mm wide; side lobes erect; mid-lobe 7-12 mm long, abruptly incurved; callus of 3-5 verrucose ridges, chiefly on mid-lobe; spur conical, stout, c. 8 mm long, slightly upcurved; fruit pendent, 30-35 mm long.
Ecology : Grassland with Terminalia, Grewia; bushland with Acacia, Clerodendrum; open woodland; pan margins in mopane woodland, on Kalahari sand, clay, sandy soils; sometimes in full sun; on sunny heights and shortly-grassed pasture slopes among gneiss rocks; stony ground, limestone or sandstone; river valleys; especially on poor soils; 300-2100 m alt.
  Very variable in size of flowers, in shapes of lip and spur.
  N Botswana, S. Africa, ? Namibia.
  Similar to E. orthoplectra but flowers smaller, spur shorter (not 13-16 mm long) and upcurved at apex. Agnew, in Upl. Kenya wild flow., ed. 2: 338, 1994, and ed. 3: 396, 2013, treats E. schweinfurthii as a synonym of E. orthoplectra. Geerinck in Fl. Rwanda 4: 575, 1988, treats E. schweinfurthii as a variety under E. orthoplectra. Often misidentified as E. speciosa.
