Habitat and Ecology [top]

Habitat and Ecology:	Amongst rocks, both limestone and granite, in semi-deciduous woodland near the Muqadrihon Pass. Altitude of 450–500 m. Two varieties have been recognised on Soqotra; var. schweinfurthii and var. papillosa which is distinguished by its narrower, more densely papillose leaves. According to Radcliffe-Smith (1987), A. schweinfurthii includes the Somali endemic Andrachne somalensis Pax but Gilbert in Flora of Somalia (Thulin 1993) maintains it as a distinct species. A. schweinfuthii is therefore considered to be endemic to Soqotra, where it is restricted to granite slopes above the Muqadrihon Pass.
