Summary
A generic description of the dioecious genus Pancheria (Cunoniaceae) from New Caledonia is accompanied by notes on the morphology of the leaves, stipules, inflorescences, flowers and fruits. Descriptions, illustrations, distribution maps and conservation assessments are provided for each of three new species. Pancheria mcphersonii occurs on Mts Panié, Colnett and Ignambi in north-eastern Grande Terre, in dense low forest and montane scrub on soils derived from mica-schist (non-ultramafic). Pancheria dognyensis grows on the Plateau de Dogny in central New Caledonia and on Roche Ouaïème and Mt Mandjélia in the north-east, in forest and especially at the forest edge, also on non-ultramafic substrates. Pancheria ajiearoana is found in central Grande Terre, in scrub on ultramafic soils. Because all three species are restricted to a small number of areas at high elevation, climate change is one of the threats that justifies giving each of them a preliminary conservation status of Endangered; as global temperatures increase, the area of habitat with a microclimate suitable for these species is likely to decrease.

Acknowledgements
We thank K, MO, NOU and P for access to specimens. Work on Pancheria by Hopkins was partly funded by a visiting research fellowship at the Museum National d’Histoire Naturelle in Paris in 2005, and initial sorting of specimens was made possible by an EU Parsyst grant at P. Herbarium facilities have been provided by P and K (Hopkins), NOU (Pillon), and MO and DAV (Bradford). Fieldwork was supported by grants from the National Geographic Society (Bradford & Hopkins) and the TOBU Fund via K (Hopkins), and we thank Bruno Fogliani and Barry Donovan for their collaboration in the field. Pillon wishes to thank staff and students at NOU and the Laboratoire d’Entomologie at IRD, the late Henri Blaffart, Steve Farino and Maurice Wanguene for help in the field, and Hervé Jourdan for identifying insects from flowers of Pancheria mcphersonii. Our thanks are also due to Maria Vorontsova and Melanie Wilmot-Dear for translating the diagnoses into Latin, to Patricia K. R. Davies for the beautiful line drawings, and to two reviewers for helpful comments on the manuscript.
