Habitat and Ecology [top]

Habitat and Ecology: Evergreen and semi-deciduous montane woodland. Altitude of 500–1,350 m.

Distinct from other species on the island in both its habit and habitat: it is the only species that grows as a tree rather than as a herbs or shrublet and is the only species restricted to the relatively moist submontane vegetation of higher altitudes in the Haggeher mountains. It is probable that I. socotrana has a different evolutionary history from that of most other Soqotran Indigofereae: these radiated in response to the advance of arid conditions throughout Northwest Africa (Schrire 1995) during the Miocene.

One of the few arborescent Indigofera species. It is scattered relatively sparsely in areas of submontane and montane woodland.
Systems: Terrestrial
