Abstract

Indigoferamonierana M.Pignal & L.P.Queiroz, sp. nov. and Indigoferadumbeana M.Pignal & L.P.Queiroz, sp. nov., two new species from New Caledonia, are described and illustrated. Both new species have been collected for a long time, but most herbarium specimens were named as the Australian species Indigoferaaustralis, even though they clearly stand apart from this species and the other New Caledonian species of the genus. Indigoferamonierana can be diagnosed by the tall virgate shrubby habit, leaves with an articulate rachis and 7–11 widely obovate to orbiculate leaflets with greyish undersurface and almost invisible venation. Indigoferadumbeana can be recognized by the arborescent habit, leaves with 15–19 elliptical leaflets, small, c. 6 mm long flowers, and ellipsoid seeds. Preliminary IUCN assessments are provided for both species. A key is provided for all species of Indigofera recorded from New Caledonia.
