Abstract
Acaena juvenca and A. emittens from lowland and montane forest margins and shrubland are described and illustrated. A. juvenca is found mainly on the east side of North and South Islands south of 39°S latitude, whereas A. emittens is restricted to central North Island. A. juvenca and A. emittens are compared with A. anserinifolia (Forster et G. Forster) J. Armstr., including A. pusilla (Bitter) Allan, in a table.
