Summary

Descriptions, illustrations, distribution maps and conservation assessments are provided for two new species of Cunonia from New Caledonia. Cunonia dickisonii Pillon & H. C. Hopkins is endemic to montane ultramafic scrub at high elevation on Mts Humboldt and Kouakoué. Cunonia koghicola H. C. Hopkins, J. Bradford & Pillon is from wet forest at low to medium elevation in the region of Mt Koghi, and irregularities in leaf shape and venation suggest it may be of hybrid origin. Microendemism on Mt Humboldt and Mt Kouakoué is briefly discussed.
