5. Siphocampylus corymbifer Pohl (1831: 112) .

= Lobelia ignea Vellozo (1831: 158) . Lectotype (designated here):— BRAZIL.São Paulo, “ Habitat ad juga Alpium Fluminensium fruticetis ”. [icon ined.] “Syng. Monog.: LOBELIA ignea Tab. 158” ( Manuscript Sect. of Torre do Tombo , Lisbon) [PT/TT/MSLIV/2778 available at https://digitarq.arquivos.pt/viewer?id=7792203], and published by Vellozo (Fl. Flumin. Icon. 8: t. 158. 1831).

Notes:—The plate for Lobelia ignea ( Vellozo 1831: 8, tab. 158) perfectly illustrates a plant of the genus Siphocampylus Pohl (1831: 104) . Its distinguishing traits are the entire corolla, with two dorsal lobes, two lateral lobes and one ventral lobe ( Fig. 1 G, H ). The morphology of the illustrated plant matches that of S. corymbifer , recognizable by the corymbose arrangement of its flowers, densely grouped at the apices of branches. This synonymy was proposed by Brako (1993).

The species, primarily known from Brazil, is also found in Bolivia. In Brazil it is found in the Distrito Federal and the states of Goiás, Mato Grosso, Minas Gerais, and Rio de Janeiro. It is more frequently associated with the Cerrado , in its Highland Rocky Fields , at altitudes of over 1000 m, but is also found in the Atlantic Forest , in High Altitude Grasslands and forest borders ( Rollim et al. 2020). According to Pastore et al. (2021), Vellozo’s term “ alpes ” (or “ alpium ”) was used to refer to the Bocaina mountain area, currently popularly known as “Virada da Serra”, and located on the way from Cunha to Paraty via BR-459, right next to the São Paulo border. The phytophysiognomy of that region is a mosaic of vegetation types, composed of open savannas (Cerrado), shrubby rocky fields, grassy wet fields, and montane ombrophilous forests ( Pastore et al. 2021).
