Cardamine latior (Brassicaceae), a new species endemic to the subantarctic Auckland Islands, New Zealand

Abstract

Cardamine latior is described as a new species endemic to Auckland Island and Adams Island. It was previously included in a broad taxonomic concept of C. subcarnosa, a species now considered to be endemic to Campbell Island. Cardamine Iatior is distinguished from C. subcarnosa by vegetative and fruit characters, including having snorter leaves with m ore leaflets, leaflets that usually overlap, more prominent leaf margin hydathodes, short and compact inflorescences, distinctly erect and broader siliques with a wider replum, and the septum with a distinct central vein. Cardamine latior is most common at higher altitudes on mountaintop screes. A description is provided and lectotype selected for C. subcarnosa. © 2008 Taylor & Francis Group, LLC.
