Justification | Known from fewer than five locations on the KwaZulu-Natal coast. Potentially threatened by coastal development, subsistence agriculture, informal settlements and alien plant invasion. Downgraded to NT due to orchids having effective long-distance dispersal allowing colonisation from subpopulations occurring outside of South Africa's borders. |

Provincial distribution | KwaZulu-Natal |
Range | KwaZulu-Natal coast, also widespread in tropical Africa. |
Habitat and Ecology |
