Habitat and Ecology [top]

Habitat and Ecology: On granite cliffs amongst granite boulders, in shrubland. Altitude of 950 m.

Distinguished from the other woody Hibiscus species on Soqotra by the combination of five-lobed, cup-shaped calyx and filiform epicalyx lobes. It is perhaps closest to H. noli-tangere but differs in the indumentum of the calyx and epicalyx, the linear not filiform epicalyx lobes and the broadly triangular calyx lobes. Only known from the type gathering on Jebal Jaaf in the eastern Haggeher. This is the only local endemic recorded from the eastern Haggeher although there is evidence of floristic differences between the eastern, central and western Haggeher.
