Abstract The history of botanical exploration of
Antipodes Island begins in 1890 and is outlined up
to 1985. The numbers of terrestrial species now
known are algae (3), fungi (2), lichens (17), liverworts
(37), mosses (21), lycopods (3), ferns (17), and
flowering plants (52). Threeof the latter are adventive
(Poa annua, Stellaria media, Sonchus asper). The
20 species of indigenous monocotyledons comprise
7 sedges,2rushes,4 terrestrial orchids, and7 grasses;
and the 29 species of indigenous dicotyledons
comprise 25 herbs, 2 semi-woody species (Acaena
minor, Coprosmaperpusilld) and 2 shrubs Coprosma
rugosa (erect), and C. ciliata (decumbent). The only
terrestrial taxa endemic to the island are Gentiana
antipoda, Senecio radiolatus subsp. antipodus, and
Stellaria decipiens var. angustata. Ten species of
flowering plants (including Coprosma cuneata), a
fern, and 2 liverworts, have been erroneously listed
from the island. Flowering times are given and
pollination is discussed. The trans-oceanic
colonisation of this relatively young Pleistocene
volcanic island is considered in terms of wind, birds
and people, and the term palynochory is proposed
for dispersal by dust-diaspores. The principal sources
have been the New Zealand mainland to the west, the
Auckland and Campbell Islands to the south-west,
and the Chatham Islands to the north. The term
Campbell Botanical Province is proposed, to include
the Antipodes, Auckland, Campbell, and Macquarie
Islands.
