title: New species ofUvariopsis(Annonaceae) andLaccosperma(Arecaceae/Palmae) from Monts de Cristal, Gabon.
abstract: Monts de Cristal National Park in northwest Gabon is one of the most species rich places in Central Africa. Here, we describe two new species, one in Annonaceae and one in palms.Uvariopsis citrataCouvreur & Niangadouma,sp. nov.is unique in the genus by emitting a strong lemon scent from the crushed leaves and young branches.Laccosperma cristalensisCouvreur & Niangadouma,sp. nov.is a rattan that lacks acanthophylls on the cirrus and has few pinnae. Complete descriptions, photographic illustrations, ecological information and preliminary IUCN conservation status are provided. For both species a data deficient (DD) status is proposed. These new species underline once again that the Monts de Cristal National Park is yet incompletely known botanically.
