About the Genus Aerangis

This genus belongs to the orchid family, and its name has been derived from two Greek words ‘aer’ (air) and ‘angos’ (urn) which refer to the shape of its lip. Nearly 50 flowering species have been classified in this genus. The orchids of this genus are mostly epiphytic or often lithophytic. All the flowers have a long nectary that is sometimes even longer than the flower itself. Most flowers are fragrant at night, and the leaves are fleshy and leathery.

Origin and Distribution

This epiphytic species of this orchid family was first discovered in the tropical lands of South Africa in 1917. It was first defined by Friedrich Richard Rudolf Schlechter. This species is also found in Mozambique, Zimbabwe, Malawi, and Zambia.

It mostly grows in riverine forests where it can actively absorb water from the nearby twigs and small plants. It is also found in evergreen forests where there is enough rainfall to fulfill its water needs.
