Novitates neocaledonicae X: A very rare and threatened new microendemic species of Acropogon (Malvaceae, Sterculioideae) from New Caledonia

Abstract : A new species, Acropogon horarius Gâteblé & Munzinger, sp. nov. (Malvaceae, Sterculioideae), is described from New Caledonia. It is known only from two very small subpopulations in the rainforests of the Petchécara Pass between Thio and Canala, in the southeast of Grande-Terre, New Caledonia’s main island. This shrub to small tree has hastate leaves and minute sessile tubular whitish-yellowish flowers and is strikingly different from all other members of the genus. The type locality is geologically complex and located within one of only four amphibolite lenses known in New Caledonia. A line drawing and colour photos are provided for the new species, along with a preliminary risk of extinction assessment, which indicates that the species is Critically Endangered.
