Marsypianthes tubulosa, a new species of Hyptidinae (Lamiaceae) from the Brazilian Cerrado

Abstract

After a brief historical account of the genus, a new species, Marsypianthes tubulosa, from the Brazilian state of Tocantins is described and illustrated. The new species is similar to M. chamaedrys (Vahl) Kuntze, the most polymorphic species of the genus. It is distinguished from the other species of the genus by its habit and characters of the cyme, calyx and corolla. Comments on the taxonomy and distribution of the new species are provided, as well as a conservation assessment, distribution map, photographs and a black and white illustration.
