Sartidia is a genus of Southern African and Madagascan plants in the grass family. It was split from Aristida in 1963 by South African botanist Bernard de Winter and contains six known species, of which Sartidia perrieri is considered extinct. Other than most species in subfamily Aristidoideae, Sartidia species use the ancestral C3 photosynthetic pathway. Their natural habitats are warm, semi-arid savanna and dry forest at altitudes of 800–2,000 metres (2,600–6,600 ft) where rainfall ranges from 250 to 1,500 mm per year. They are perennial grasses with inflorescence in a panicle.
