on the north-west shore of Hokianga Harbour, occasional elsewhere
in North Auckland, Auckland (Rangitoto Island) and Bay of Plenty

In many parts of the
tropics, this species is a dangerous weed, being poisonous
to livestock, although it has never been a problem in NZ. Lantana

Accord (see Introduction for details). Other forms and species
