Habitat and Ecology [top]

Habitat and Ecology: Scattered on limestone cliffs in dry, semi-deciduous woodland. Altitude of 20–550(–1,050) m.

A narrower concept of this species has been adopted here (compared to that of Thulin and Al-Gifri 1998), including all cliff-rooting trees bearing leaves with white-felted undersurfaces. It is found on limestone (and occasionally granite) cliffs in central-northern and central-southern Soqotra and includes. Two, distinct forms can be recognized: those with entire, rather regularly crenate leaves, found in the wadis draining to the south of the island; and those with simple or deeply lobed leaves with irregularly crenate and somewhat sinuate margins from the limestone areas to the northwest of the Haggeher mountains. Trees in Wadi Terubah bearing both entire and simple leaves are possibly the result of hybridsation with B. elongata. A dwarf, prostrate form of B. popoviana (cf. forms of B. nana) was recently also found on the limestone ridge at Heger (between Riy di Isfer and Riy do Sherubrub) limestone in the extreme west of Soqotra above Bandar Shu'ub.
Systems: Terrestrial
