Abstract: Rediscovery of Barleria maclaudii (Acanthaceae) in Guinea after 86 yearsBarleria maclaudii Benoist (Family Acanthaceae) grows in savannah and woodland mosaics on lateritic slopes at - m altitude.Described by Raymond Benoist in , it was initially discovered in Fouta-Djalon (Guinea) in .Formerly, the most recent observation in Guinea was in , near Dinguiraye.Additionally, it has been recorded in Senegal and Mali, with a total of - localities across these three countries.The extent of these localities is poorly understood, as they are only known from seven herbarium specimens.For these reasons, and because of known threats at some of these localities, the species is categorized as Endangered on the IUCN Red List.However, in October , after years without records, B. maclaudii was rediscovered in Guinea, around the village of Kokoun Thimbobhé (sub-prefecture of Kollet), within the Moyen-Bafing National Park in Fouta-Djalon.During November -June , the species was recorded in c. more localities in the Park, with half of these in the core protected area and high conservation value zones.The localities cover a total extent of occurrence c. , km , and we estimate that the total known area of occupancy is at least km , with a population size of c. , individuals.The altitude range of the localities is - m, slightly exceeding the previously known upper limit.Barleria maclaudii Benoist in Kokoun Thimbobhé (Moyen-Bafing National Park): (a) habitat and (b) inflorescence with a flower.
