Acaena is a
The
Several Acaena species in New Zealand are known by the common name bidibid. The word is written variously bidi-bidi, biddy-biddy, biddi-biddi, biddi-bid and a number of other variations. These names are the English rendition of the original Māori name of piripiri.[3] The plant is also called the New Zealand burr. The species Acaena microphylla has gained the Royal Horticultural Society's Award of Garden Merit.[4]
Etymology
The generic name Acaena is derived from the Greek "akaina" (thorn), referring to the spiny hypanthium.[5]

Invasive species
Some species have been introduced accidentally to other areas, attached to sheep's wool, and have become invasive species. Acaena novae-zelandiae, one of the bidibids from New Zealand, is the most commonly encountered species in the United Kingdom, where it is often abundant on coastal sand dunes, crowding out native vegetation and creating an often painful nuisance with the barbed burrs. In California, A. pallida, A. novae-zelandiae and A. anserinifolia are considered serious weeds.[7]
