Two new species of Chamaecrista sect. Absus (Leguminosae, Casesalpinioideae) from Brazil and Bolivia with phylogenetic delimitation

Two new species of Chamaecrista from Brazil and Bolivia are identified, which are designated here as C. oppositifolia and C. longistyla, both of which belong to C. sect.

Tricky Morphology: A New Species of Chamaecrista (Leguminosae) Shows Strong Morphological Convergence among Not Closely Related Species Found in Similar Habitat

Phylogenetic analyses revealed that C. acicularis is not closely related to other quite similar needle- like leafleted species and that this trait evolved convergently, and an informal conservation status is presented for all needle-like Leafleted species.

A Taxonomic Revision of Chamaecrista (Caesalpinioideae, Cassieae, Cassiinae) in Southern Africa

A detailed taxonomic revision of the species of Chamaecrista indigenous to the flora of southern Africa region is conducted, including comprehensive descriptions, a key to the species, nomenclature, typifications, diagnostic characters with illustrations, and geographical distribution maps of all recognised taxa.

Morphological Studies of Chamaecrista sect. Absus ser. Setosae (Leguminosae) with Emphasis on the Chamaecrista setosa Complex, Including a New Species

Abstract Chamaecrista is one of the largest genera of Leguminosae, subfamily Caesalpinioideae. Traditionally, it has been divided into six sections, of which Chamaecrista sect. Absus is the largest,

A new infrageneric classification of the pantropical genus Chamaecrista (Fabaceae: Caesalpinioideae) based on a comprehensive molecular phylogenetic analysis and morphology

A new infrageneric classification is proposed for Chamaecrista supported by molecular phylogenetic analyses and morphology, recognizing the four main clades as sections Apoucouita, Baseophyllum, Chamaicrista and Absus, the last with three subsections, but it does not recognize any previously circumscribed series.



Self-compatible sympatric Chamaecrista (Leguminosae-Caesalpinioideae) species present different interspecific isolation mechanisms depending on their phylogenetic proximity

Inter-incompatibility represents an important factor in reproductive isolation and thus in the maintenance of the genetic identity of sympatric taxa that flower in synchrony and share pollinators.

A flora dos campos rupestres da Cadeia do Espinhaço

Os campos rupestres abrigam um dos maiores patrimomios biologicos brasileiros e sua conservacao depende do conhecimento amplo e detalhado of suas especies e dos mecanismos envolvidos na dinâmica de suas populacoes.

Phylogeny of Calliandra (Leguminosae: Mimosoideae) based on nuclear and plastid molecular markers

A new infrageneric classifica- tion is proposed for Calliandra, and the African species of the genus are assigned to a new genus, Afrocalliandra, based on phylogenetic relationships in Leguminosae subfam.

Phylogeny of Chamaecrista Moench (Leguminosae­Caesalpinioideae) based on nuclear and chloroplast DNA regions

These analyses suggest that the diversification patterns in Chamaecrista occurred through an initial shift from rainforest trees to a more diverse clade of savannah shrubs, more diverse in open grassland areas and includes many colonizers of waste ground.

Phylogeny of Chamaecrista ser. Coriaceae (Leguminosae) Unveils a Lineage Recently Diversified in Brazilian Campo Rupestre Vegetation

Molecular and morphological data indicated that a narrower definition of Chamaecrista ser.

Toward Defining the Course of Evolution: Minimum Change for a Specific Tree Topology

A method is presented that is asserted to provide all hypothetical ancestral character states that are consistent with describing the descent of the present-day character states in a minimum number of changes of state using a predetermined phylogenetic relationship among the taxa represented.

Glacial history and colonization of Europe by the blue tit Parus caeruleus

It is suggested that after the last Ice Ages, the blue tit subspecies have colonized Europe from two different southern refuges following previously proposed general recolonization routes from the Balkans to northern and Central Europe, and from the Iberian Peninsula north- and eastwards.

Phylogenetic patterns and diversification in the caesalpinioid legumes

The chloroplast matK gene, and the trnL and 3′-trnK introns for 153 genera of caesalpinioid legumes are sequenced and Parsimony and Bayesian phylogenetic analyses of these data support the monophyly of several major groups within the Caesalpinsia clades.
