Ecology : High-rainfall woodland; (mixed) deciduous woodland; Brachystegia, Brachystegia/Uapaca or Cryptosepalum woodland; on trunks and big horizontal branches of trees, usually sunk in moss and (Usnea) lichen; on, e.g., Julbernardia globiflora, Brachystegia, Monotes, Uapaca kirkiana, Eucalyptus; on rocks in woodland; “on slopes and ridges where there is constant movement of air, never in hollows” (la Croix & al., Orchids Malawi: 267, 1991); very local; 1200-2050 m alt.

  The most distinctive species of Cyrtorchis, much sought after by orchid growers, but possibly the trickiest to grow, and reluctant to flower; not easy to obtain. For cultivation, see Bot. Mag. 20/4: 217, 2003.
