Angiosperms and the Linnean shortfall: three new species from three lineages of Melastomataceae at one spot at the Atlantic Forest

Three new species of Angiosperms have been found in four short collection trips to the same protected reserve—"Estação Ecológica Estadual de Wenceslau Guimarães"—and neighboring areas in the Atlantic Forest in the south of the Brazilian state of Bahia. These new species belong to three genera from three distinct lineages in the family Melastomataceae: Huberia, Meriania and Physeterostemon. The description of these species represent a good example of a Linnean shortfall, i.e., the absence of basic knowledge about the biodiversity in the area, as well as in tropical forests as a whole. The description of these probably endemic species per se is a signal that this area deserves more attention regarding research and policies, but its consequences go farther: this area has a relevant role as a phylogenetic (both genetic and morphological) stock, and thus is also valuable as a phylogenetic conservation priority.
