Craterostigma is a genus of shrub-like flowering plants in the family Linderniaceae, found in Africa, Madagascar, (island of) Socotra, the Arabian Peninsula, the Indian Subcontinent, Sri Lanka, China, Southeast Asia and Java. The best studied species is the resurrection plant Craterostigma plantagineum, known for its unique drought tolerance.
The word 'craterostigma' comes from two Greek words, krateros meaning cup-shaped and stigma, part of the female reproductive part of a flower.Gwithie Kirby
