Abstract Helichrysum lanceolatum is a
widespread and variable New Zealand species that has been regarded as a
species complex. A survey of genetic variation in Helichrysum lanceolatum using
AFLP, nrDNA ITS sequence, and cpDNA psbA–trnH
sequences is presented. No evidence to support segregate taxa at any
rank was found. Geographic structure in genetic diversity is weak and
consistent with a model of increasing genetic isolation with distance.
