<i>DE MACROCARPAEAE GRISEBACH (EX GENTIANACEIS) SPECIEBUS NOVIS </i> X: A SYNOPSIS OF THE GENUS IN MONTANE ATLANTIC FORESTS OF BRAZIL

Outside of the principal distribution and major diversification of <i>Macrocarpaea</i> in the Andes, smaller groups of species are found in the Greater Antilles of the Caribbean, Mesoamerica, the Guayana Highlands, and montane Atlantic forests of Brazil. Here, a complete revision of the genus in the latter region is presented recognizing eight species that correspond to the entirety of <i>Macrocarpaea</i> sect. <i>Tabacifoliae</i>: <i>M atlantica</i> J.R. Grant & V. Trunz, <i>sp. nov.</i>, <i>M. dolichophylla</i> J.R. Grant & V. Trunz, <i>sp. nov.</i>, <i>M. glaziovii</i> Gilg, <i>M. illecebrosa</i> J.R. Grant, <i>M. inesiae</i> J.R. Grant & V. Trunz, <i>sp. nov.</i>, <i>M. obtusifolia</i> (Griseb.) Gilg, <i>M. orbiculata</i> J.R. Grant & V. Trunz, <i>sp. nov.</i>, and <i>M. rubra</i> Malme. These species occur primarily in humid coastal montane rainforests (Mata Atlântica), and two species also occur in <i>campos rupestre</i> montane savannas.
