About

Raphia australis, the giant palm, Kosi Palm, or rafia, is a species of raffia palm in the family Arecaceae. It is found around Kosi Bay in southern Mozambique and northeastern KwaZulu Natal in South Africa. It is threatened by habitat loss caused by drainage of its habitat for agriculture; it is being threatened in the Bobole Special Reserve but is more secure in the Kosi Bay area.

Where it grows

Raphia australis is endemic to Gaza Province in southern Mozambique and near Kwangwanase at Kosi Bay in KwaZulu Natal in South Africa. There are four subpopulations, the largest one being at Manhiça District in Mozambique where there are about 4,000 mature individuals. This palm grows in swamps, peat bogs and seasonally flooded dunes.
