“…e species occur in campos rupestres (quartzitic rock outcrops), cerrado (savanna), low land grasslands, campos de altitude (highland grasslands), caatinga vegetation (seasonaly dry tropical forests) and savanna hillsides; in lateritic, sandy soils or with rock outcrops. Exceptionally, there are some shade-loving species, which occur in the understory of forests and woodlands, such as G. hispidula, G. brasiliensis, and G. laxa (Cabral & Bacigalupo 1997;Cabral 2009;Cabral & Salas 2015;Carmo et al 2016). Galianthe comprises 50 species grouped in two subgenera: Galianthe subg.…”

ABSTRACTirteen species of the genus Galianthe have been recorded for state of Rio Grande do Sul, Brazil. e species are distributed among seven biomes, one of which contains all thirteen taxa-Subtropical Seasonal Forest. Herein a new endemic species, G. riograndensis J. Florentín & E.L. Cabral, is described, illustrated and di erentiated from all other species of the genus by having 3-4 verticillate leaves and a long bi d style. In addition, the pollen grain morphology and the seed micromorphology of the new species are described and illustrated, and the conservation status assessed according to IUCN criteria. Moreover, G. chodatiana is recorded for the rst time from the state, and a lectotype for G. equisetoides is designated. Most of the species of Galianthe are described and illustrated with detailed photos of living specimens. A taxonomic key for species identi cation, as well as comments on distribution, overall phenology and habitat, are also presented. e distribution of the new species is discussed in the context of the biogeographic region of the state, and maps and a table of species by biome are also provided.

“…Only the 10 percent of the Galianthe species were assessed for conservation status (Zappi et al 2013, Carmo et al 2016, Florentín et al 2017a, Florentín et al 2017b, and considering that most of them are of restricted distribution in South America, they are in need of a conservation assessment which is thus here provided.…”

Full descriptions of four Galianthe species, complemented by new data on fruits and seed characters are presented. These species occur at 500–3000 m elevations: G. gertii and G. reitzii in southeastern Brazil; G. guaranitica in eastern Paraguay and central-western Brazil; and G. boliviana in the sub-Andean region of northern Bolivia and southern Peru. Conservation status, with comments on distribution, is provided for three of them and is reassessed for one. The lectotypification of G. guaranitica is discussed.

ResumoEste estudo teve como objetivos realizar o levantamento florístico da família no município de Camanducaia, Serra da Mantiqueira, extremo sul de Minas Gerais, onde extensos remanescentes de Mata Atlântica são encontrados, e elaborar uma Chave Interativa de Entradas Múltiplas (CIEM) para a identificação das espécies. O levantamento florístico foi realizado através de viagens de coleta e análise dos seguintes herbários: BHCB, ESA, HRCB, IAC, ICN, MBM, SP e UEC. Rubiaceae está representada em Camanducaia por 35 espécies, duas subespécies e duas variedades, classificadas em 17 gêneros. Borreria, Manettia e Psychotria foram os gêneros mais diversos (cinco espécies cada). Nove espécies, uma subespécie e uma variedade são endêmicas da Mata Atlântica. Duas espécies (Galianthe vaginata e Psychotria beyrichiana) são endêmicas da Serra da Mantiqueira e Serra do Mar. Psychotria beyrichiana é registrada pela primeira vez em Minas Gerais. Através da utilização da CIEM aqui proposta, a maioria dos táxons puderam ser identificados utilizando-se somente caracteres vegetativos.

AbstractThis study aimed to conduct a floristic survey on the family in the municipality of Camanducaia, Serra da Mantiqueira, southern Minas Gerais, where extensive remnants of Atlantic forest are found, and to produce an Interactive Key of Multiple Entries (IKME) for the identification of the species. The floristic survey was based on field expeditions and the analisys of the following herbaria: BHCB, ESA, HRCB, IAC, ICN, MBM, SP and UEC. Rubiaceae is represented in Camanducaia by 35 species, two subspecies and two varieties, classified in 17 genera. Borreria, Manettia and Psychotria were the most diverse genera (five species each). Nine species, one subspecies and one variety are endemic to the Atlantic forest. Two species (Galianthe vaginata e Psychotria beyrichiana) are endemic to the Serra da Mantiqueira and Serra do Mar. Psychotria beyrichiana is recorded for the first time in Minas Gerais. The utilization of the IKME here proposed made possible the identification of most of the taxa by utilizing only vegetative characters.
