Novelties in South American Garcinia (Clusiaceae): Tying loose ends across biomes

We present two taxonomic novelties in Garcinia (Clusiaceae): a new species to the Brazilian Atlantic Forest, Garcinia bahiensis Mouzinho & L.Marinho sp. nov. ined., endemic to the hygrophilous forests of southern Bahia state, whose specimens were previously determined as G. macrophylla Mart.; and the redescription of G. guacopary (S.Moore) M.Nee, a species distributed in the transition areas between the Amazon and Cerrado domains that were neglected in previous studies. The taxonomic treatment consists of morphological descriptions, photographic plates, distribution maps, and morphological discussions with related species. Regarding G. guacopary, we present images of live specimens and their current known distribution for the first time, with a considerable range expansion, besides the designation of a lectotype. After G. bahiensis description, segregated from a broader G. macrophylla concept, Garcinia no longer shares species between the Amazon and Atlantic Forest domains.
