Habitat and Ecology [top]

Habitat and Ecology:Seaward-facing limestone cliffs in shrubland dominated by Rhus thyrsiflora and Ballochia amoena. Altitude of 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. A (now described as Justicia alexandri).
