THE VEGETATION OF WHALE ISLAND

PART II. SPECIES LIST OF V A S C U L A R PLANTS

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 plant 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 New Zealand' Vol . 1 by H.H. Allan (1961); indigenous monocotyledons, 'Flora of New Zealand' 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).
