Habitat and Ecology [top]

Habitat and Ecology: A rare shrub of sheltered slopes on the highest granite pinnacles of the western Haggeher; associated with Euryops arabicus, Helichrysum rosulatum, Hypericum tortuosum and Thamnosma socotrana. Altitude of ca. 1,500 m.

Restricted to limestone cliffs at Reqadihon (above Hoq). These cliffs capture mist and cloud during the winter and are an eastern outlier for a number species (e.g., Coelocarpum haggierensis and Dirachma socotrana) which are otherwise found only in areas of high rainfall in the Haggeher mountains. This species is closely related to Justicia sp. nov. B (now described as Justicia takhinensis).
Systems: Terrestrial
