Information regarding the use of beneficial, native Brazilian plants was compiled by European naturalists in 19th century. The French botanist Auguste de Saint-Hilaire (1779-1853) one most important such naturalists; however, his manuscripts (field books) have not yet been studied, especially context useful plants.To present data documented field book Brazilians.Data on were obtained from books (six volumes) deposited Muséum national d' Histoire naturelle Paris, France. vernacular names...
Dorstenia acangatara (Moraceae), a new species, endemic to the Atlantic rainforest between Espírito Santo and Minas Gerais states, in Southeastern Brazil is described illustrated. D. considered threatened by IUCN standards due its restricted geographic area of occurrence.
The new Franco-Brazilian website "Saint-Hilaire virtual herbarium" offers dynamic online consultation of all specimens and manuscripts the naturalist Auguste de Saint-Hilaire, providing links between specimen images associated textual data, including notes available in his field books. This tool aims at facilitating work taxonomy systematic botany allowing a more accurate reconstruction routes time frame Saint-Hilaire's exploration. All are being digitized by Paris herbarium (P) added...
Ant-plant mutualisms are abundant in the tropics and popular models for ecological study, but investigating origin evolution of such systems requires a phylogenetic framework.A common ant-plant mutualism Neotropics involves genus Cecropia, group fast-growing pioneer trees that important forest regeneration.Relationships between genera tribe Cecropieae (Urticaceae), including Coussapoa, Musanga, Myrianthus, Pourouma, unknown necessary to investigate evolutionary history Cecropia-ant...
During the course of floristic studies on Urticaceae in Distrito Federal, Brazil, we encountered a species Pilea that was not described until now. brasiliensis is here and illustrated, its affinities are discussed position Weddell & Killip’s subdivisions genus indicated. A Conservation Assessment determines P. to be Critically Endagered (CE) with possibility it may Extinct Wild (EW).
A Serra da Mantiqueira, localizada na Região Sudeste do Brasil, encontra-se entre os biomas Mata Atlântica e Cerrado, se estendendo pelos estados de São Paulo, Minas Gerais, Espírito Santo Rio Janeiro. Sua maior porção está no estado Gerais a menor Santo, Caparaó. Ficus L. é o gênero família Moraceae, com aproximadamente 800 espécies distribuídas região tropical, incluindo arbustivas, arbóreas, hemiepífitas trepadeiras. As características mais marcantes são inflorescência tipo sicônio...
Studies that place the origin of stem node Ficus in Gondwana or Eurasia at c. 136–134 Mya are not congruent with estimated Moraceae Late Cretaceous. To elucidate these origins, molecular analyses were performed using three calibration points BEAST 268 terminal taxa based on ITS, ETS, G3pdh, ncpGS and GBSSI sequences. S-DIVA, DEC S-DEC used to estimate ancestral areas. The arrangement staminate flowers within syconium supports current phylogenetic framework Ficus. Our results suggest lineage...
Abstract The infrageneric nomenclature of Ficus , the largest genus in Moraceae, is reviewed. We call attention to three overlooked subgeneric names, F . subg. Terega Raf., Sycomorus Raf. and Spherosuke four sectional sect. Cordifoliae G. Don, Pogonotrophe (Miq.) Miq., F. Platyphyllae Mildbr. & Burret Urostigma (Endl.) Griseb., that have priority over other long‐used names. also effect a new combination into based on Apiosycea Miq. In addition, we designate types for 6 generic 17
O presente trabalho objetivou inventariar o componente de trepadeiras por meio estudos florísticos, fitossociológicos e aspectos fenológicos em trecho Mata Ciliar na Estação Ecológica da Fazenda Campininha Mogi Guaçu (22º10'43"-22º18'19"S 47º08'05"-47º11'34"W). No estudo florístico foram coletadas 89 espécies, distribuídas 54 gêneros, pertencentes a 25 famílias. quantitativo amostrou 43 espécies com os maiores valores importância para Adenocalymma bracteatum, Forsteronia australis...
O presente trabalho objetivou inventariar o componente de trepadeiras em fragmento Floresta Ombrófila Densa do Parque Estadual das Fontes Ipiranga. As coletas ocorreram entre janeiro 2006 e junho 2007. Foram encontradas 187 espécies, distribuídas 109 gêneros, pertencentes a 32 famílias. Foi elaborada chave para determinação além ilustrações descrições sucintas. famílias com maior riqueza específica foram Fabaceae (21), Bignoniaceae (20) Asteraceae (20). Os gêneros número espécies Mikania...
Abstract Ficus subg. Pharmacosycea sect. has never been comprehensively sampled in previous phylogenetic analyses of Ficus. The published phylogenies have focused mostly on the study whole genus, with a sampling only few taxa fromthis group. Our represents first molecular analysis focusing this section, including 27 terminals representing 20 its 35 species and 31 other three nuclear DNA sequences (ITS, G3pdh, ETS) add considerably to our knowledge relationships within peculiar lead proposed...
Urticaceae está representada por sete gêneros e 14 espécies na área do Parque. Destas, 11 são nativas três cultivadas (Pilea cadierei Gagnep. & Guillaumin, Pilea nummulariifolia (Sw.) Wedd. Boehmeria nivea Jacq.). Foram incluídos os Cecropia com Coussapoa uma espécie.
Dorstenia stellaris is a new species from southeastern Brazil. This endemic to the region and differs others by its star shaped coenanthium cordiform leaves. A description illustration of this presented here. found in moist shady places, small populations within type locality, thus we recommend inclusion endangered (EN) status conservation.
Resumo Este estudo engloba as espécies de Urticaceae registradas nas vegetações cangas da Serra dos Carajás, Pará, trazendo descrições detalhadas, ilustrações e comentários morfológicos das espécies. Foram encontrados cinco gêneros sete para a área estudo.
Abstract— This work presents the new taxon Ficus series Dugandii characterized by syconium ostiolar margin with wall curved to outer side of syconium, forming a short apical tube, irregularly rounded triangular. For this study, field trips were carried out and collections herbarium specimens, types, protologues analyzed. The has 15 species 50 synonyms proposed here, distributed from Mexico Antilles southeastern Brazil. Names like F. llanensis , llewelynii, mitrophora previously synonymous,...
A Serra da Mantiqueira é uma formação montanhosa que ocupa importante área do Sudeste brasileiro. Entre as famílias ricas em espécies na composição flora está Moraceae, sendo Dorstenia se destaca como o segundo gênero mais representativo número de espécies, depois Ficus. Neste trabalho são apresentadas descrições, observações sobre fenologia e distribuição geográfica, comentários ilustrações das nativas (Moraceae). Após levantamento bibliográfico análise material coletado herbário foi...
A new species of Sorocea A. Saint-Hilaire, S. carautana M. D. Vianna, Carrijo & Romaniuc (Moraceae s. str.), was discovered in the hills southern Rio de Janeiro vicinity Paraty. The resembles hilarii Gaudichaud by similar shape leaves, but is clearly distinguished its longer pistillate pedicel. This endemic to Atlantic Forest and threatened due restricted geographic area occurrence.
Abstract A new species of Ficus sect. Pharmacosycea, endemic to the municipality Barbacoa, Narino, Colombia is here described and illustrated as dewolfii Pederneiras & Romaniuc. It characterized by a caudate leaf apex lateral veins diverging from midrib almost at right angle, shows similarities with F. rieberiana, apollinaris, mutisii.
Abstract Sorocea longipedicellata (Moraceae) is described and illustrated as a species new to the Atlantic rainforest domain. The related group of with completely spinulose dentate leaf margins. It includes bonplandii S. guilleminiana, but distinguished mainly by elongated pedicels when fruiting. This known only from Bahia state, northeastern Brazil designated critically endangered because its extent occurrence estimated be less than 100 km2 in an extremely fragmented area.
