Schatz, G.E., R.E. Gereau & P.P. Lowry II (2017). A revision of the endemic Malagasy genus Beguea (Sapindaceae). Candollea 72: 45–65. In English, English and French abstracts.
A taxonomic revision of the endemic Malagasy genus Beguea Capuron (Sapindaceae) is presented. While Capuron in 1969 originally recognized a single, variable species (Beguea apetala Capuron), a careful reevaluation of all available material allows us to recognize ten species, nine of which are described as new, on the basis of numerous floral and vegetative characters. Material of only two of the new species was available to Capuron, and was included in his broad circumscription of Beguea apetala, whereas all material of the remaining seven new species has been collected since 1992. The nine species are illustrated by line drawings, and several species are documented by field photographs. The geographic distribution of each species is presented and mapped, and a preliminary risk of extinction assessment is provided using the IUCN Red List criteria.
