Chautems, A., V.F. Dutra, A.P. Fontana, M. Peixoto, M. Perret & J. Rossini (2019). Three new species of Sinningia (Gesneriaceae) endemic to Espírito Santo, Brazil. Candollea 74: 33–42. In English, English abstract. DOI:  http://dx.doi.org/10.15553/c2019v741a5

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.
