Forsskaolea tenacissima
Forsskaolea tenacissima is a member of the non-stinging nettles genus Forsskaolea and is in the same family as the stinging kind, Urticaceae. Described as "looking like a tough character that does not want or need a caress", F. tenacissima makes its home where not many plant species survive, in stony soils, road edges, in the gravel wadi
and "in the rock crevices and water-receiving depressions" above the stone pavements of the Hamadas.
