Three new species of Sinningia (Gesneriaceae) endemic to Espírito Santo, Brazil

Three new species of Sinningia Nees (Gesneriaceae) occurring in eastern Brazil and endemic to the state of Espírito Santo are described and illustrated: Sinningia flammea Chautems & Rossini, Sinningia hoehnei Chautems, A.P. Fontana & Rossini and Sinningia stapelioides Chautems & M. Peixoto. Sinningia flammea is unique within the genus by its tubular bright orange corolla with a greenish-yellow throat. Sinningia hoehnei is characterized by white corollas that are laterally and ventrally inflated for most of their length with a yellow throat marked by vinaceous streaks. Sinningia stapelioides strikingly differs from any other species by the combination of a pauciflorous inflorescence borne directly on the tuber that produce large tubular–campanulate corollas, dull red orange outside, inside greenish-cream with a dense network of vinaceous streaks. Comments on morphologic and phylogenetic relationships within the subtribe Ligeriinae are provided, as well as a distribution map and the IUCN  conservation status.
