Abstract

Nuclear ITS sequences and ISSR profiles provide evidence that Raoulia rubra is endemic to the Tararua Range in the southern part of the North Island of New Zealand. Populations in the South Island previously ascribed to R. rubra are better ascribed to R. eximia. Our findings suggest that glaciation of the central mountains of the South Island during the last ice age have had a major impact on the evolution of the South Island cushion Raoulia species in New Zealand. However, simple hypotheses accounting for the effect of Pleistocene climate change are insufficient to explain patterns of endemism in the group.
