THE VEGETATION OF WHALE ISLAND PART II. LIST OF VASCULAR

by B.S. Parris*

ABSTRACT A list of vascular plants found on Whale Island is presented together with the abundance of each species and the communities in which it occurs.

INTRODUCTION This list was drawn up during the July visit and only a few species were added on the August visit. Further collections at more favourable seasons would probably add more species, particularly adventive annuals, to the list. The plant communities are as in Parris et al. (1971). Specimens of most species are lodged in the herbarium of the Auckland Institute and Museum. Nomenclature is as follows: indigenous dicotyledons and ferns, 'Flora of ' Vol. 1 by H.H. Allan (1961); indigenous , '' Vol. 2 by L.B. Moore and E. Edgar (1970); adventive species, 'Handbook of the Naturalised flora of New Zealand' by H.H. Allan (1941) and 'A Guide to the Identification of Weeds and Clovers' by A.J. Healy (1970).
