The wild plants of Niue
The Auckland Museum Herbarium holds over 400 plant specimens from Niue, dating back to 1877. The main collectors are: Henry A. Mair, a New Zealand sea-trader, who collected 35 ferns there in 1877; S. Percy Smith, a New Zealand civil servant and amateur ethnologist, who collected 125 mainly flowering plants in 1901; and botanist Rhys Gardner, research associate of Auckland Museum, who collected a similar number in 2005.
Gardner published two personally-illustrated books on the flora: Trees and Shrubs of Niue (2011) and Ferns and herbs of Niue (2013); and two papers in 2021 on the flora: The naturalised flora of Niue and The native vascular plants of Niue, SW Pacific. There are no known plants endemic to Niue.
