  author={Richard W. Jobson and Melissa A. Luckow},
Abstract We undertook a phylogenetic study of the genus Piptadenia with a sample of 18 of ca. 27 recognized species using DNA sequences from the plastid Trnl-F and trnK/matK regions. Parsimony jackknife results support the hypothesis that Piptadenia is polyphyletic and that there are three independent lineages. The largest groups of species form a monophyletic lineage that is sister to Mimosa and corresponds closely to Piptadenia section Piptadenia sensu Barneby. Three species (P. obliqua, P… 

Misleading fruits: The non-monophyly of Pseudopiptadenia and Pityrocarpa supports generic re-circumscriptions and a new genus within mimosoid legumes

Recognition of Parapiptadenia, Pityrocarpa and Marlimorimia as distinct genera is also supported by combinations of morphological traits, several of which were previously overlooked.

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.

Molecular Phylogeny of Stryphnodendron (Mimosoideae, Leguminosae) and Generic Delimitations in the Piptadenia Group

Increased molecular and taxonomic sampling improved the resolution of a previously largely unresolved clade that included Microlobius, Parapiptadenia, Pityrocarpa, PseudopiptadenIA, and Stryphnodendron, suggesting rapid and recent diversification in both savannas and rain forests in the Neotropics.

Toward a Phylogeny of Mimosa (Leguminosae: Mimosoidae): A Preliminary Analysis of Southern South American Species Based on Chloroplast DNA Sequence1

A preliminary phylogenetic analysis of chloroplast nucleotide sequences from 34 species of Mimosa and related genera suggests that the representatives from sections Calothamnos and Mimosa share a common ancestor with those from section Habbasia and section Batocaulon ser.

Section Mimadenia: its phylogenetic relationships within the genus Mimosa (Leguminosae, Mimosoideae) using plastid trnL–F sequence data

A phylogenetic analysis of chloroplast nucleotide sequences of the trnL–trnF intergenic spacer from 36 species of Mimosa, and six related genera indicated that genus Mimosa is monophyletic, and the species of section Mimadenia constitute a clade sister to the rest of the genus.

Sanjappa , a new genus in the tribe Ingeae ( Leguminosae : Mimosoideae ) from India

Cladistic analyses based on morphological and molecular data show that C. cynometroides does not nest with the currently recognised species of Calliandra, but forms a well-supported distinct monophyletic lineage with Faidherbia A. Chev.

The evolutionary history of Mimosa (Leguminosae): toward a phylogeny of the sensitive plants.

A preliminary phylogenetic framework for Mimosa is established that can be used to infer patterns of morphological evolution and relationships and which provides pointers toward a revised infrageneric classification.

Phylogenetic patterns in the tribe Acacieae (Caesalpinioideae: Fabaceae) based on rbcL, matK, trnL-F and ITS sequence data

The tribe Acacieae is one of the three tribes of the distinct mimosoid clade nested within the re-circumscribed sub-family Caesalpinioideae. Many uncertainties exist with the taxonomic status of

Genetic diversity of symbiotic Paraburkholderia species isolated from nodules of Mimosa pudica (L.) and Phaseolus vulgaris (L.) grown in soils of the Brazilian Atlantic Forest (Mata Atlântica).

Multilocus sequence analysis and BOX-PCR analyses indicated that six clusters of Paraburkholderia represent potential new species and in the phylogenetic analysis of the nodC gene, the majority of the strains were positioned in the same groups as in the 16S rRNA-recA tree, indicative of stability and vertical inheritance.

Taxonomic Revision of the Vachellia acuifera Species Group (Fabaceae: Mimosoideae) in the Carribean

Twelve Caribbean species of Vachellia (formerly Acacia subgenus Acacia) are formally monographed with taxonomic, habitat, geographic distribution descriptions, and lists of representative specimens examined, showing that these species form discrete groups in two- and three-dimensional plots.




This study highlights the inevitability of recognising segregate genera from Acacia s.l., and the necessary abandonment of Bentham’s longstanding tribal classification.

A Phylogenetic Analysis of the Acacieae and Ingeae (Mimosoideae: Fabaceae) based on trnK, matK, psbA-trnH, and trnL/trnF Sequence Data

A phylogenetic analysis of exemplars of Acacieae, Ingeae, and some Mimoseae, based on trnK, matK, psbA-trnH, and trnL/trnF sequence data, supports other recent studies in showing that neither the IngeAE nor AcacIEae is monophyletic.

Saccifolium (Saccifoliaceae), an endemic of Sierra de la Neblina on the Brazilian-Venezuelan border, is related to a temperate-alpine lineage of Gentianaceae

Saccifolium appears to be the sister group of Gentiana and has a basal position in clade E (subtribe Gentianinae Gilg pro parte), a derived clade comprising globally distributed temperate-alpine gentians.

Five new taxa of Piptadenia (Leguminosae: Mimosoideae) from Brazil

Three of the taxa are closely related to plants growing thousands of kilometres from the Bahian localities and, as such, present fascinating phytogeographical disjunctions.

Notes on Mimosoideae: VIII

Important changes in the nomenclature of certain genera and species dealt with in Part I of these Notes are made, notably that the genus then called Pityrocarpa now becomes Piptadenia Benth.

Universal primers for amplification of three non-coding regions of chloroplast DNA

Six primers for the amplification of three non-coding regions of chloroplast DNA via the polymerase chain reaction (PCR) have been designed and worked for most species tested, which means that they may be used to study the population biology and evolution of plants.

The Parsimony Ratchet , a New Method for Rapid Parsimony Analysis

The Parsimony Ratchet is presented as a new method for analysis of large data sets. The method can be easily implemented with existing phylogenetic software by generating batch command files. Such an

The Parsimony Ratchet, a New Method for Rapid Parsimony Analysis

With the ratchet, Goloboff's NONA, and existing computer hardware, data sets that were previously intractable or required months or years of analysis with PAUP* can now be adequately analyzed in a few hours or days.
