Ecology and distribution
Trop. Afr.
Biology : Terrestrial, epiphytic (usually) or lithophytic herb 15-90 cm tall, glabrous, with many thick fleshy roots; leaves cauline, 6-8, petiolate (3 cm), in lower part of stem; blade elliptic, 7-30-60x1,5-7 cm, decreasing in size up the stem; flowers resupinate, white; bracts ovate-lanceolate, 18-20-35 mm long; pedicel and ovary 45-60 mm long; dorsal sepal ovate, much convex, 8-12x5-8 mm; laterals deflexed, ovate, 10-12x c. 6 mm; petals entire, oblanceolate, 9-12x3-7 mm; lip 3-lobed from rectangular claw 2-6 mm long, lobes linear; midlobe 11-18 mm long, side-lobes 10-27 mm; spur filiform, 47-110-160 mm long, curved, slightly swollen in apical half.
Ecology : Rain-forest, among ferns and mosses on trunks and in axils of branches of several tree species; often on Elaeis guineensis; in humus among rocks, and in shady rock fissures; lava flows; damp shady areas by rivers; grassy places amongst rocks; damp or swampy places with Cyperaceae; herbaceous fringes of inselbergs; cocoa plantations; 0-1600 m alt.
  Very variable species.
  – Habenaria procera, Scleria melanotricha, Utricularia andongensis are character species of the Sclerio melanotrichae-Habenarietalia procerae plant community (Parmentier & Müller in Phytocoenologia 36: 573-581, 2006; also ibid.: 547-564),described from West and Atlantic Central Africa. Forming xeric mats and occurring in herbaceous fringes on inselbergs. 3 varieties have been recognised (but there is much overlap between them), viz. var. procera with floral bracts to 35 mm long, pedicel 8-15 mm; var. gabonensis with floral bracts to 20 mm long, pedicel 20-35 mm, in W part of range; var. psiloceras with spur 130-160 mm long, in Angola-Zambia; H. ochyrae, terrestrial, was described from SW Congo-Brazzaville, Bouenza Falls (3°53’Sx13°42’E), on a differing flower lip structure; its bracts are up to 20 mm long, pedicel and ovary 50 mm, spur 85-90 mm long.
