Acaena echinata, commonly known as sheep's burr, is a species of perennial herb, in the Rosaceae family, native to Australia.
It grows to a height of 25âÂÂ40 cm (9.84âÂÂ15.75 in) and has shiny, green fern-like leaves 6âÂÂ15 cm (2.36âÂÂ5.91 in) long which are hairy on the underside. Its tiny pale green flowers form a spike and have purple stamens. The burrs it produces are sharply barbed.
The Latin specific epithet of echinata refers to hedgehog, from echinus meaning 'prickly'.
