Cortaderia sp. in New Zealand: patterns of genetic variation in two widespread invasive species
Cortaderia selloana (pampas grass) and C. jubata (purple pampas grass) are both invasive in New Zealand. Cortaderia selloana is found throughout most of the country, whereas C. jubata is restricted to the North Island and the northern South Island. We examine the genetic variation present in each of the species, and compare this to the findings of an earlier study that analysed the variation in invasive C. jubata plants from New Zealand.
