Chamaegigas intrepidus (Scrophulariaceae) is a tiny, most remarkable resurrection plant growing endemically in ephemeral rock pools on granite outcrops in Central Namibia. Habitat conditions are characterised by (1) frequent and fast desiccation and rehydration during the rainy summer season and complete dehydration during the dry winter season lasting up to 11 months, (2) intensive solar irradiation and high temperatures during the dry season, (3) diurnal oscillations of pH in the pool water up to 6 units, (4) extreme nutrient deficiencies, especially nitrogen.
