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. |
