This member of the Gesneriaceae family was given this name by Alain P. Chautems, Mauro Peixoto and Josiene Rossini in 2015. It is found in Rio de Janeiro and Espírito Santo regions in south-eastern Brazil, growing in a well drained soil with some water and some to lots of sun. The caudex can grow to three or even ten centimetres in diameter, the entire plant to 20 or even 50 centimetres in height. The flowers are purple. The genera is named after Wilhelm Sinning,1792–1874, a gardener of the Botanische Gärten der Friedrich-Wilhelms-Universität Bonn. The species name honours Dr. João Marcelo de Alvarenga Braga, the active plant collector and taxonomist working at the Rio de Janeiro Botanical Garden, who found it.
