Abstract An annotated vascular flora of 282 taxa for Aorangi
Island, Poor Knights Islands, is presented. Additional records (20 taxa) from
Tawhiti Rahi Island, the other major island in the archipelago, are listed
separately, resulting in a combined Poor Knights vascular flora of 302 taxa.
Two new combinations,
Wahlenbergia littoricola subsp.
vernicosa
and
Xeronema callistemon f.
bracteosa, are made for plants
previously treated as
W. vernicosa and
X. callistemon var.
bracteosa, respectively. Only one taxon,
Xeronema callistemon f.
bracteosa, is provisionally accepted as endemic to the Poor Knights
Islands. The control of the more serious weed species on the island is
discussed. A case is made for including the Mokohinau Islands within the Poor
Knights Ecological Region.
Keywords Poor Knights Islands; annotated vascular plant list;
taxonomy; endemic plants; ecological region; ecological district; environmental
