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.

Keywords  Asteraceae; Gnaphalieae; genetic variation; Helichrysum lanceolatum; AFLP; nrDNA ITS; cpDNA
