Abstract
A recent worldwide phylogeny of Sapindaceae inferred from nuclear and plastid DNA regions segregated the Malagasy Haplocoelum perrieri Capuron from the African Haplocoelum foliosum (Hiern) Bullock. Additional phylogenetic analyses conducted here (including material of H. inopleum Radlk., the generi-type) confirmed the result from the previous analysis and showed that maintaining a broad circumscription of Haplocoelum to include the Malagasy species would render the genus polyphyletic. In order to maintain monophyly, it is necessary to exclude H. perrieri, which we transfer to a new, monotypic genus, described here as Gereaua Buerki & Callm.. This taxon is easily distinguished from the species retained in Haplocoelum by the following morphological characters: (1) sexual dimorphic inflorescences in racemules (vs. monomorphic inflorescences in fascicule of cymes); (2) 2-locular ovary (vs. 3-locular ovary); (3) rudimentary ovary in staminate flowers (vs. ovary well developed in staminate flowers); (4) corolla with 4-5 petals (vs. apetalous); (5) glabrous anthers (vs. pubescent anthers); (6) pubescent fruit (vs. glabrous fruit). Relationships with the most-closely related genera, comprising in the Macphersonia group, are discussed in light of molecular, morphological and biogeographic evidence. A preliminary threat assessment of G. perrieri (Capuron) Buerki & Callm. using the IUCN Red List criteria indicates a status of Least Concerned.
