Abstract The classification of the legume family proposed here addresses long‐known non‐monophyly traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new uses as its framework most comprehensive phylogenetic analyses legumes to date, based on plastid matK gene sequences, and including near‐complete sampling genera (698 currently 765 genera) ca. 20% (3696) known species. region has been widely sequenced across legumes, in...

Background DNA barcoding has been successfully established in animals as a tool for organismal identification and taxonomic clarification. Slower nucleotide substitution rates plant genomes have made the selection of barcode land plants much more difficult task. The Plant Working Group Consortium Barcode Life (CBOL) recommended two-marker combination rbcL/matK pragmatic solution to complex trade-off between universality, sequence quality, discrimination, cost. Methodology/Principal Findings...

The utility of 18S and 26S in broad phylogenetic analyses has been much maligned due large part to the low signal both genes. However, few have employed complete rDNA sequences over a range taxa, most alignments two genes are done de novo, without taking into account secondary structure rRNA Here we mine next-generation sequence data compile matrices (429 taxa) + gene sequences, compare novo alignment methods with curated by eye that take hard-to-align regions (profile alignments). combined...

Eighty-four specimens of <i>Oryzomys subflavus</i>, collected in the State Pernambuco, Brazil, were studied. A Robertsonian chromosome polymorphism, characterized by a varying diploid number 50, 49, 48, and 46, was found. All showed arm 56. G-banding patterns somatic cells allowed identification pairs (2, 3, 5, 7) involved centric fusion. C-banding revealed presence constitutive heterochromatin near centromere X those autosomes. The Y presented large heterochromatic block distal...

Mikania glomerata Sprengel and Mikania laevigata Schultz Bip. ex Baker are native Brazilian lianas, popularly known as guaco and mainly used as bronchodilators. Based on morphological and anatomical leaf features, preliminary data indicate substantial similarity between the two species, requiring further studies to increase accuracy of their diagnosis. However, it is still unclear which species commercially sold. Therefore, in analysis, three individuals each were treated according usual...

Chaetostoma hexapetalum, a new species from Chapada dos Veadeiros, Goias state, in the central-western region of Brazil, is described and illustrated. This can be easily differentiated its congeners by combination following characters: presence sixmerous flowers, four-locular ovary, fruits with slight apical prolongation, two glandular trichomes between opposite leaves. Images seeds made scanning electron microscopy, photos field, distribution map are presented. A key to occurring de...

The genus Maria Vianna was proposed by et al. (2013: 290) for a small group of the tribe Dorstenieae (Moraceae), components undergrowth in rainforests tropical Africa. However, as authors chose later homonym, M.D.M.Vianna is an illegitimate name (Art. 53.1 ICN, McNeill 2012). This discovered after checking nomenclature fossil plants, which suggested Jefferson Prado. It confirmed that I.A.Dobruskina (1980: 92) valid gymnosperm (Peltaspermaceae). In accordance with Code, new generic Hijmania...

Comolia is a neotropical genus currently represented by 10 accepted species. Since the description of genus, 47 names have been published within it. When investigating these names, we found that some them needed to be typified. The aim present study was provide nomenclatural treatment for Comolia, including list all synonyms related its species, typifications and comments, when necessary. Thirteen lectotypes one neotype are designated here. Six were lectotypified using two illustrations. In...

A historic net of pathways referred to as Peabiru was constructed connecting the southern Brazil with Peruvian Andes. The path disappeared during Colombian era but an important testimony Brazilian preColombian epoch. To understand human migrations around we examined genetic relationship modern landraces and archaeological maize considering ADH2 gene.Peabiru sequences were grouped Andine specimens suggesting early exploitation this path, involving Andian people Guarany natives, endorsing...

Abstract Dorstenia, the second largest genus of Moraceae, comprises nine sections that are mainly found in Africa and America. Two them woody macrospermous, other seven herbaceous microspermous. There three Neotropics, all which taxonomically complex owing to their great morphological similarity. The most recent molecular phylogenetic studies Dorstenia suggested neotropical polyphyletic. These also showed species represent a sister group an African macrospermous grade rather than...

(Nomenclatural novelties in Miconieae (Melastomataceae): new synonym and typifications). This contribution provides diagnostic morphological characters, geographic distribution data, synonymizations typifications for three species of Miconieae. We clarify the taxonomic status Clidemia raddiana as a Miconia capilliflora designate its lectotype. For capillaris leptopus, we provide nomenclatural adjustments, due to similarity epithets characteristics. also lectotype neotype, respectively, these...
