Microlicieae are a monophyletic tribe comprising seven genera: Chaetostoma, Lavoisiera, Microlicia s.s., Poteranthera, Rhynchanthera, Stenodon and Trembleya. Microlicia s.s. includes 172 species predominantly distributed in the campo rupestre of Brazil. Its delimitation is complex because the generic boundaries, mostly with Lavoisiera and Trembleya, are unclear. Here we present a phylogenetic analysis for Microlicieae focusing on Microlicia s.s., with the specific goals: (1) to test the monophyly of Microlicia s.s.; (2) to investigate morphological characters that could help in circumscribing clades and/or genera in the tribe and (3) to provide an appropriate classification for Microlicia s.s. and related genera. This study was based on plastid (atpF-atpH, trnS-trnG), nuclear ribosomal (nrITS, nrETS) and nuclear low-copy (waxy) DNA sequences, through maximum likelihood and Bayesian inference analyses. The history of 12 morphological characters was estimated based on ancestral state reconstruction analyses. Our analysis shows Microlicia s.s. to be paraphyletic with Chaetostoma, Lavoisiera, Stenodon and Trembleya nested in it. Most characters traditionally used to diagnose these genera are homoplastic. We propose the inclusion of these four genera in a broadly circumscribed Microlicia s.l., and provide new combinations and names for their species. As here defined, Microlicieae has three genera, Rhynchanthera, Poteranthera and Microlicia s.l., Microlicia s.l. being the fourth richest genus in Melastomataceae with c. 245 species.

Resumo A Serra dos Pireneus, localizada na porção centro-oeste do estado de Goiás, está representada prioritariamente por fisionomias das formações campestres e savânicas, onde a família é bastante diversa. O presente estudo apresenta o tratamento sistemático das 77 espécies de Melastomataceae catalogadas para a Serra dos Pireneus. Espécimes depositados nos herbários CEN, ESA, HUEG, HUFU, IBGE, K, MBM, RB, SP, UB, UEC e UFG foram analisados. Chave de identificação para as espécies, descrições com comentários taxonômicos e ilustrações de caracteres diagnósticos são fornecidos.

-(Melastomataceae in RPPN of the Clube Caça e Pesca Itororó, Uberlândia, Minas Gerais State, Brazil). The present study aimed to do a floristic inventory and a taxonomy treatment of Melastomataceae from the RPPN of the Clube Caça e Pesca Itororó Uberlândia, State of Minas Gerais, Brazil. We found 28 species in 12 genera. Miconia is the most diverse with eight species, followed by Microlicia (four spp.), Siphanthera (three spp.

Abstract—Microlicia gertii, M. purpurata, and M. trianae from Serra do Cabral, Serra da Canastra, and Serra do Bota, Minas Gerais, Brazil, respectively, are presented here. Comprehensive descriptions of the new species, including detailed illustrations and comparisons with their relatives are provided. The statements of geographical distribution, habitat, and informal IUCN conservation status for each species are indicated. Additionally, the leaf anatomy of three new species is described.

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.

Three new species of Microlicia endemic to Serra do Cipó, Minas Gerais state, Brazil, are described here. Microlicia joaosemiriana and M. longiglandulosa are characterized by their sessile leaves, congested flowers at the apex of the branches, dimorphic stamens with tetrasporangiate and bicolorous anthers. However, M. joaosemiriana differs in having hypanthium and sepal covered only with spherical glands and sepal shorter than the hypanthium length. Microlicia longiglandulosa has hypanthium and sepal with glandular trichomes mixed with spherical glands and sepal longer than the hypanthium length. Microlicia jolyana has a petiolate and thickened leaf, lanceolate to oblong leaf blade, rounded to slightly acuminate at the apex, smooth and not striate hypanthium surface, triangular-oblong and thickened sepal, dimorphic stamens, and purple to purple-blackish anther on both whorls. Also, Microlicia linifolia var. naudiniana is elevated to species rank with a new name (Microlicia acerosa), and M. nortecipoana and M. petiolulata are synonymized under M. hirtoferruginea. Additionally, we provide an updated checklist of Microlicia species in the Serra do Cipó.

Abstract—Microlicia longirostrata (Melastomataceae), a new species from Goiás, is described and illustrated, and a discussion on leaf anatomy is also provided. The new species resembles M. consimilis and M. psammophila, but differs from them in having an indumentum with both short-stalked, spherical, glandular trichomes and long-stalked, glandular emergences, polysporangiate anthers and antesepalous stamens with a very long beak (2‐2.5 mm long), and annular collenchyma on the adaxial region of the midrib.
