Aponogeton ranunculiflorus, the Sehlabathebe water lily, is a tiny and endangered species[3] of aquatic plant, that belongs to the pondweed family Aponogetonaceae. It is protected in the Sehlabathebe National Park in the mountains of Lesotho, where it is very localised,[3] and nearby in the uKhahlamba / Drakensberg Park of KwaZulu-Natal, South Africa.[1] Outside these areas it is seriously threatened. It is found in sandstone rock pools, up to 7 metres deep, and in permanently wet tarns or sensitive high altitude mires,[1] at altitudes between about 2,600 and 3,200 metres. Its spiralled stems allow the flowers to remain at surface level.[3] Threats to the species include overgrazing and trampling by cattle, overburning, erosion and subsistence farming.[1] Their small (1 cm) corms can survive the drying out of the pools, or being frozen into the muddy bottoms.[4]
