摘要
Alternanthera nahui is named and described as a new species from New Zealand. It was previously included in A. sessilis, but differs from that species by its narrower leaves, keeled tepals, shorter staminodes, and a shorter style. nrDNA ITS sequence data imply that A. nahui is most closely related to A. denticulata, and it differs from that species by its smaller stature, having shorter and narrower leaves with less denticulate margins.
