Paepalanthus aleurophyllus, a new species of Eriocaulaceae from Minas Gerais, Brazil

We describe and illustrate Paepalanthus aleurophyllus (Eriocaulaceae, Paepalanthoideae). The species is narrowly distributed, restricted to the Pico do Itambé in Minas Gerais, Brazil. Detailed comparisons are made with P. diplobetor and P. ciliolatus. Paepalanthus aleurophyllus is distinguished by its densely ciliated leaves with dolabriform to fusiform trichomes in the adaxial leaf surface, conspicuous venation on the abaxial leaf surface, trichomes between the scape ribs, general habit, and other floral features. We provide detailed line drawings and commentaries on distribution, ecology, and conservation.
