Abstract Olearia buchananii Kirk is known from a
single nineteenth-century collection reputedly gathered by pioneer botanist
John Buchanan from an unknown New Zealand locality. However, following critical
comparison of the type of
Olearia buchananii with the type and
additional specimens of the Australian
O. viscosa (Labill.) Benth., we
conclude that these species are conspecific. Present-day knowledge of the
biogeography of
Olearia suggests that
O. viscosa is unlikely to
be indigenous to New Zealand.
Although the exact circumstances of how
this Australian endemic came to be in New Zealand are not known, it seems most
likely that the specimen may have originated from either exchange specimens or
live plants sent to New Zealand by Australian botanist Ferdinand von Mueller. A
lectotype is selected for
Olearia viscosa.
