Ecology and distribution
Trop. Afr.
Biology : Epiphytic (hanging), sometimes lithophytic, entirely glabrous herb; stem simple, woody, pendulous or ± horizontal, 12-60 cm long, leafy, rooting at nodes; leaves ligulate, fleshy, in one plane in 2 rows, 3-13x0,8-2,5 cm, surface slightly rugose; inflorescences borne opposite leaves, very short (to 4 cm), crowded with flowers (3-12); rachis zigzag; bracts not imbricate; flowers white or cream, tinged with apricot or pink, scented or not; sepals ovate, 5-10x2-4 mm; petals oblong-elliptic, 5-8x2-3 mm; lip 7-12x7-10 mm, 3-lobed near base, side lobes rounded and erect, mid-lobe oblong, 5-10x5-8 mm, emarginate; spur wide-mouthed, 9-11 mm long, bent and constricted at middle, apex inflated. – Forming large clumps like mistletoe.
Ecology : Drier forests; forest-savanna boundaries; high rain-fall Brachystegia woodland; savanna; old secondary forests with Celtis sp., Sterculiaceae; in tall forest trees, isolated in areas formerly forested; gallery and riverine forest; in coastal areas and isolated hills inland; sometimes on rocks; often at high level on tree boles and branches up to 35 m above soil; on, e.g. Brachystegia boehmii, Mangifera indica, Uapaca heudelotii, Diospyros sp.; on Vitellaria (Selbyana 27: 74, 2006); growing with Polystachya affinis; 0-1900 m alt.
  Small specimens can resemble Tridactyle anthomaniaca, but roots are thicker and leaves longer (Malawi). – Often confused with C. emarginatum.
  Used in traditional medicine (Burkill, Useful pl. W. Trop. Afr., ed. 2, 4: 315-316, 1997; Morris in Orchid Rev. 111/1253: 274, 2003).
  Subspontaneous in Brazil, Mata Atlântica (Barros & al., Orchidaceae in Forzza & al., Catálogo de plantas e fungos do Brasil 2: 1359, 2010). One of the most widespread of all African epiphytic orchids.
