Ecologie et distribution
Afr. Trop.
Biologie : Herb 25-35 cm tall; corm 1-2 cm Ø; fibers usually accumulating in a dense mass, often extending upwards and with the dry cataphylls forming a thick neck; leaves linear, to 25 cm x 1,5-7 mm; spike 4-10-flowered; bracts 1,8-2,5 cm long; flowers light to dark purple; tube 1-1,2 cm long; dorsal tepal 1,6-2 cm long.
Ecologie : Copper hill; lightly copper-enriched steppe, summit of ore deposit; poisoned dambo south of metal-bearing hill; steppe with termite mounds; meadow rich in malachite; meadow with Eragrostis, Xerophyta; meadow with Sporobolus, copper rich; steppe on sand with many Lentibulariaceae; humid steppe near gallery; humid steppe; 1050-2100 m alt. A species from heavy-metal-enriched soil; but also away from such habitats. Capsules of plants growing on sandy or stony soils are not known, and without seeds their identity is difficult to determine.
  Near G. gregarius, and considered a variety of the latter by, e.g., Geerinck (cf. Goldblatt in Fl. Trop. E. Afr., l.c., i.e. var. angustifolius).
