Three specimens of the endemic Cruckshanksia montiana (which has no English or local Spanish name) growing in coastal sand-dunes in the southern Atacama Desert region of Chile. Confined to Chile, this species can exist with very little water although, in years when the desert receives rain, Cruckshanksia will comprise some of the ‘flowering desert’ flora that happens particularly when there is an El Niño warming of the nearshore Pacific Ocean. This species has vivid yellow flowers surrounded by larger, equally yellow sepals, presumably to attract pollinators, while the regular green leaves grow close to the sand.
