A taxonomic revision of the genus Acaena in Chile was carried out, using morphological characters.

The following species are lectotypified: A. alpina Poepp. ex Walp., A. caespitosa Gillies ex Hook. et Arn., A. integerrima Gillies ex Hook. et Arn., A. macrocephala Poepp., A. magellanica (Lam.) Vahl, A. pinnatifida Ruiz et Pav., A. platyacantha Speg., A. splendens Hook. et Arn., and A. tenera Alboff. The following species were neotypified: A. lucida (Aiton ) Vahl, A. sericea J. Jacq., and A. trifida Ruiz et Pav. var. glabrescens Regel et Körn.
