A new species from New Caledonia, Dendrobium veillonii M. Pignal, sp. nov. is described and illustrated. Morphological characters that distinguish the new taxon from the related species, D. pectinatum Finet, D. crassicaule Schltr. and D. cleistogamum Schltr., are outlined, and IUCN conservation status is proposed. An identification key is given for the sect. Kinetochilus Schltr. Lectotypes are designed for D. cleistogamum, D. crassicaule et D. pectinatum. The architecture of the section Kinetochilus Schltr. based on D. veillonii M. Pignal, sp. nov. is analysed.
