Apomictic plants are less dependent on pollinator services and able to occupy more diverse habitats than sexual species. However, such assumptions based temperate species, comparable evaluation for species-rich Neotropical taxa is lacking. In this context, the Melastomataceae a predominantly angiosperm family with many apomictic which common in Campos Rupestres, endemism-rich vegetation rocky outcrops central Brazil. study, breeding system of some Campo Rupestre was evaluated, studies New...

Abstract Microlicieae are a monophyletic tribe comprising seven genera: Chaetostoma, Lavoisiera, Microlicia s.s., Poteranthera, Rhynchanthera, Stenodon and Trembleya. s.s. includes 172 species predominantly distributed in the campo rupestre of Brazil. Its delimitation is complex because generic boundaries, mostly with Lavoisiera Trembleya, unclear. Here we present phylogenetic analysis for focusing on specific goals: (1) to test monophyly s.s.; (2) investigate morphological characters that...

In heterantherous flowers, some anthers have an attraction and feeding function, while others are related to plant reproduction. Microlicia cordata has dimorphic stamens organized in two cycles: the antesepalous one with large pink anthers, antepetalous small yellow anthers. Division of labor was analyzed using parameters structure, composition, amount estimated viability pollen, color floral parts. The pollinating were larger than stamens, although anatomically similar. There a difference...

Poteranthera (Melastomataceae) is a genus of small, annual herbs with narrow leaves, that inhabit humid savannas in South America and are visible only when bloom. Due to their size paucity collections, the phylogenetic position has been uncertain this point. at times associated, confused, or placed Acisanthera and/or Siphanthera. Phylogenetic analyses based on DNA sequence data place unequivocally within Microlicieae not closely related Siphantera. These results consistent seed anther...

Tenerife is one of the most well monitored islands Canaries, but surveillance generally centred on Las Cañadas Caldera, where Teide volcano located. In last 180 000 yr, eruptions Island have never occurred in same volcanic structure, except for and Pico Viejo central system, so that a complete monitoring network would to cover whole island. As result, Synthetic Aperture Radar Interferometry (InSAR) being used Tenerife, because this space technique can provide displacement map surface earth...

Abstract Two new species of Microlicia (Melastomataceae) endemic to campos rupestres from the Espinhaco mountain range in Minas Gerais, Brazil, are described and illustrated, a discussion on leaf anatomy is also provided. cogniauxiana similar M. graveolens, passerina, tomentella by having an indumentum stalked glands, pink pink-magenta petals, dimorphic stamens with bicolored anthers. It can be distinguished its leaves noticeable veins adaxial surface, glandular-ciliate margins. naudiniana...

In Microlicieae taxonomical delimitation of Lavoisiera , Microlicia and Trembleya is problematic. This study aims to fill this gap by identifying leaf characters that are useful for taxonomy these genera. Species Rhynchanthera were also included in comparison, since it an early‐diverging genus the tribe. Diagnostic include sessile leaves with spongy parenchyma composed isodiametric cells, acute margins supporting tissue. distinguished petiolate, microphyllous, hypostomatic leaves. The...

RESUMO Um inventário florístico foi realizado entre abril de 2002 a novembro 2003, e mais duas expedições em 2005 outubro 2006 nas serras do município Delfinópolis, sudoeste Minas Gerais. Todos os espécimes coletados estão depositados no Herbarium Uberlandense (HUFU). As Melastomataceae são representadas por 52 espécies distribuídas 17 gêneros. Miconia (17 spp.) é o gênero com maior número espécies, seguido Microlicia (7 spp.), Leandra Tibouchina (5 spp. cada), Svitramia (4 Cambessedesia (3...

Abstract During a floristic survey of Melastomataceae carried out in Biribiri State Park and around Diamantina, Minas Gerais State, Brazil, we found new species Microlicia, which is endemic to campos rupestres from the Espinhaco Mountain Range. Microlicia longicalycina has flowers with long calyx lobes, dense indumentum glandular trichomes on hypanthium, leaves light green ciliate margin, mix pale, thickened, trichomes. A discussion leaf anatomy provided.

A seção Chaetostomoides (Naudin) Cogn. é constituída por uma única espécie, distribuída essencialmente nos campos rupestres de Minas Gerais, Bahia e Goiás. Nesta revisão aceita apenas M. viminalis (DC.) Triana , sinonimizadas sob esta, loricata Naudin virgata Cogn., suas variedades angustifolia Pilger, glabrescens gracilis Pilger subpatens Pilger. São apresentadas descrição, comentários ilustrações da espécie.

The genus Microlicia comprises approximately 130 species, the characters that define species are very often tenuous, making delimitation between closely related difficult. As a result of taxonomic study on Microlicia, 14 new synonyms proposed here and 10 lectotypes designated.

Studies carried out in Minas Gerais state have led to the rediscovery of Microlicia maximowicziana and M. riedeliana, known previously only by type collections made 190 years ago LudwigRiedel. We present descriptions, commentson theaffinities among closelyrelatedspeciesandconservationassessments, as well illustrations. Lectotypes for both species are designated varieties synonymised.

Two new species of Microlicia from campos rupestres Minas Gerais are described, illustrated and compared with their relatives. crassa sp. nov. is similar to M. formosa , maculata isophylla tetrasticha . The trichomes covering both surfaces the leaves two relative, may be characterized as sessile glands under a stereomicroscope, but anatomical studies revealed presence short stalk. assessed “Endangered”, according IUCN categories criteria.

Abstract A new species of Microlicia (Melastomataceae) from Goias state is described and illustrated, a discussion on leaf microscopy also provided. chrysoglandulosa sp. nov. resembles M. martiana, psammophila, tenuifolia by the slender fastigiate branches, triangular sepals, stamens with tetrasporangiate thecae. However, it differs remarkable indumentum spherical short-stalked glandular trichomes internodes, abaxial surfaces andmargins, pedicels, hypanthium sepals. The presence bright...

Microlicia furnensis, a new endemic species from campos rupestres of Capitólio municipality, Minas Gerais state, Brazil, is described and illustrated. The characterized by its cream petals with pale pink blotches at the apex, sessile or subsessile leaves golden glandular trichomes short covering leaves, pedicels, hypanthium calyx lobes. It resembles M. confertiflora, isophylla flava, latter also occuring in Capitólio, state. A list Melastomataceae mountains municipality provided.

A new species of Microlicia from Serra do Cipó (southern Espinhaço range, Brazil) is described and illustrated. candolleana has branches, leaves, pedicels, hypanthium sepals covered by spherical, golden glands, sessile leaves with evident nerves on both surfaces subulate sepals, longer or the same length as hypanthium.

RESUMO O presente estudo teve como objetivo o inventário e tratamento taxonômico das Melastomataceae encontradas na RPPN do Clube Caça Pesca Itororó Uberlândia, MG, Brasil. Durante foram 28 espécies distribuídas em 12 gêneros. Miconia é gênero mais diverso com oito espécies, seguido por Microlicia (quatro spp.), Siphanthera (três Rhynchanthera, Tibouchina, Trembleya Leandra (duas spp. cada), Acisanthera, Cambessedesia, Desmoscelis, Lavoisiera Macairea, apenas uma espécie cada.
