Abstract The taxonomy of
Utricularia monanthos Hook.f.
and
U. novae-zelandiae Hook.f. (Lentibulariaceae) from New Zealand is
evaluated. These two taxa are also discussed in relation to
U. dichotoma
Labill. and
U. monanthos from Australia. Data on vegetative and floral
characters were obtained from herbarium specimens in New Zealand and Australia,
and from field work on existing natural populations throughout New Zealand.
Considerable variation and similarity of characters was found among material
described under
U. dichotoma,
U. monanthos, and
U.
novae-zelandiae, with no clear delineation between taxa evident. We
therefore suggest that all material be placed under
U. dichotoma. The
distribution of
U. dichotoma (
U. novae-zelandiae sens. lat. and
including
U. monanthos sens. str.) for New Zealand was also examined. A
map showing its present known occurrence, and the location of previous records,
where the plant may now be extinct, is provided.
