Ecologie et distribution
Afr. Trop.
Biologie : Herb 30-65 cm tall; corm 1,5-3 cm Ø, tunics light red-brown; leaves 4-several, the lower 3-5 are 0,4-1,2 cm wide, stiff with heavily thickened margins, midribs and at least 2 other veins, the thickening raised and arching over the blade surface; blades at least 15 cm long, usually reaching to at least base of spike; spike 2-6-flowered; bracts 3-7 cm long; flowers white, each of the 3 lower tepals with a dark purple streak in lower midline; tepals ± equal, ± obovate, apiculate.
Ecologie : Meadows on rocky soils or rocks; 1100-1800 m alt.
  Very near and probably a synonym of G. leonensis; also near G. aequinoctialis but the flower in G. praecostatus has perianth tube 8-12,5 cm long, tepals 3,2-3,5 cm long (not 8,5-14 cm, nor 3,5-4 cm).
  The 3 taxa G. iroensis, G. praecostatus, G. aequinoctialis are doubtfully distinguished from the E. African G. murielae.
  Occurs in the Nimba Mts (S Guinea-N Liberia-neighbouring Ivory Coast). – Not mapped.
