“…Bayer (found to be nested within Alstroemeria by Sanso & Xifreda, 2001). For Alstroemeria , species concepts followed Bayer (1987) for the Chilean species and Assis (2001) for the Brazilian species. For Ecuadorian Bomarea , species concepts followed Harling & Neuendorf (2003); for the remaining Bomarea , we followed Hofreiter & Tillich (2002).…”

Aim The Alstroemeriaceae is among 28 angiosperm families shared between South America, New Zealand and/or Australia; here, we examine the biogeography of Alstroemeriaceae to better understand the climatic and geological settings for its diversification in the Neotropics. We also compare Alstroemeriaceae with the four other Southern Hemisphere families that expanded from Patagonia to the equator, to infer what factors may have permitted such expansions across biomes. Location South America, Central America, Australia and New Zealand. Methods Three chloroplast genes, one mitochondrial gene and one nuclear DNA region were sequenced for 153 accessions representing 125 of the 200 species of Alstroemeriaceae from throughout the distribution range; 25 outgroup taxa were included to securely infer evolutionary directions and be able to use both ingroup and outgroup fossil constraints. A relaxed‐clock model relied on up to three fossil calibrations, and ancestral ranges were inferred using statistical dispersal–vicariance analysis (S‐DIVA). Southern Hemisphere disjunctions in the flowering plants were reviewed for key biological traits, divergence times, migration directions and habitats occupied. Results The obtained chronogram and ancestral area reconstruction imply that the most recent common ancestor of Colchicaceae and Alstroemeriaceae lived in the Late Cretaceous in southern South America/Australasia, the ancestral region of Alstroemeriaceae may have been South America/Antarctica, and a single New Zealand species is due to recent dispersal from South America. Chilean Alstroemeria diversified with the uplift of the Patagonian Andes c. 18 Ma, and a hummingbird‐pollinated clade (Bomarea) reached the northern Andes at 11–13 Ma. The South American Arid Diagonal (SAAD), a belt of arid vegetation caused by the onset of the Andean rain shadow 14–15 Ma, isolated a Brazilian clade of Alstroemeria from a basal Chilean/Argentinean grade. Main conclusions Only Alstroemeriaceae, Calceolariaceae, Cunoniaceae, Escalloniaceae and Proteaceae have expanded and diversified from Patagonia far into tropical latitudes. All migrated northwards along the Andes, but also reached south‐eastern Brazil, in most cases after the origin of the SAAD. Our results from Alstroemeria now suggest that the SAAD may have been a major ecological barrier in southern South America.

“…Floristic studies carried out over the last 15 years in this part of Minas Gerais state (Nakajima & Semir 2001;Romero & Martins 2002;Farinaccio & Mello-Silva 2004;Scudler 2004;Pontes & Mello-Silva 2005;Filardi et al 2007;Carvalho-Silva & Guimarães 2009;Hemsing & Romero 2010;Morokawa et al 2013), suggest that the region has a high number of endemic species from different families of Angiosperms (Romero & Goldenberg 1999;Romero & Nakajima 1999;Assis 2002;Romero & Guimarães 2005;Cavalcanti 2007;Batista & Bianchetti 2010;Chautems et al 2010;Feres 2010;Dutra & Garcia 2013;Farinaccio 2013). Melastomataceae is considered one of the most representative families in campos rupestres of this region with more than a hundred species (Romero & Martins 2002;Silva & Romero 2008), from which at least five are endemic (Romero & Goldenberg 1999, Romero 2000, Romero & Guimarães 2005.…”

Microlicia furnensis, a new endemic species from campos rupestres of Capitólio municipality, Minas Gerais state, Brazil, is described and illustrated. The new species is characterized by its cream petals with pale pink blotches at the apex, sessile or subsessile leaves and golden glandular trichomes and short pale trichomes covering the leaves, pedicels, hypanthium and the calyx lobes. It resembles M. confertiflora, M. isophylla and M. flava, the latter also occuring in Capitólio, Minas Gerais state. A list of species of Melastomataceae from the mountains of Capitólio municipality is also provided. Key words: campos rupestres, endemic, Furnas, Microlicieae, Serra da Canastra ResumoMicrolicia furnensis, uma nova espécie endêmica dos campos rupestres das serras do município de Capitólio, Minas Gerais, é descrita e ilustrada. A nova espécie caracteriza-se por apresentar pétalas creme com manchas rósea-claro no ápice, folhas sésseis ou subsésseis e tricomas glandulares dourados e tricomas setosos, curtos recobrindo as folhas, pedicelo, hipanto e lacínias do cálice. Assemelha-se a M. confertiflora, M. isophylla e M. flava, esta última também com ocorrência em Capitólio, estado de Minas Gerais. Uma listagem das espécies de Melastomataceae das serras do município de Capitólio é fornecida.

“…Alstroemeria com 44 espécies possui distribuição peri-amazônica concentrada basicamente na porção leste do país. Ocorre em quase todos os tipos de hábitats: florestas, cerrados, campos de altitude, brejos, afloramentos rochosos e caatingas, em altitudes que variam de 300 m, na Amazônia, a 2300 m, na Serra do Itatiaia, sendo que a maioria das espécies tem distribuição relativamente restrita (Assis 2001(Assis , 2002(Assis , 2003(Assis , 2004a(Assis , 2006(Assis , 2007(Assis , 2009Assis & Mello-Silva 2002;Sanso et al 2005). Esta distribuição restrita contribui para que muitas das espécies sejam consideradas ameaçadas de extinção segundo os critérios da IUCN (2003), incluidas na categoria venerável (VU) e em perigo (EN).…”
