title: Dorstenia triseriata (Moraceae) a new and endangered species from Brazil.
abstract: A new species of Moraceae is described, illustrated and compared to its close morphological relatives. Dorstenia triseriata presents similarities with Dorstenia turnerifolia but distinguished by size of peduncle, diameter of receptacle, number of bract rows, color of marginal bracts, and by an indistinct fringe on inflorescence. A conservation assessment based on IUCN criteria determines the new species to be vulnerable (VU).
