Checklist of dicotyledons, gymnosperms, and pteridophytes naturalised or casual in New Zealand: Additional records 2004–06

Abstract

New records of Naturalised and Casual plants are reported for the flora of New Zealand during the 3 yr period 2004–06. Six species are reported as fully naturalised and 162 taxa are considered to be new records of casual plants. To reflect the modes of establishment of weeds in the Casual category, and to enhance the information content of the new Casual records, we propose a new classification scheme that further subdivides this into Cultivation escape, Spontaneous Occurrence, garden Discard, and Intentional Release.
