The prickly head grasses ( Triodia ) are a genus of plants in the sweet grass family . It only occurs in Australia. Prickly head grasses cover large parts of the outback in Australia ; over 20% of the continent is covered with it.

The prickly head grasses are also known under the name Spinifex . Botanically, however, Spinifex is a genus of coastal grasses that is not closely related to the Triodia species in the interior. Barbed head grasses are difficult to digest for cattle, which is why only extensive grazing or no livestock farming can take place in the area where this genus is distributed.
