Zoysia macrantha, the prickly couch, is a type of grass.
It is a creeping perennial plant found near the coastal dunes and inland salt marsh habitats in South Eastern Australia. Two subspecies are recognized, Zoysia macrantha subsp. macrantha and Zoysia macrantha subsp. walshii. The specific epithet macrantha is derived from Greek, meaning large flower.[1] [2] [3] [4]
