• Premise : Bromeliaceae form a large, ecologically diverse family of angiosperms native to the New World. We use bromeliad phylogeny based on eight plastid regions analyze relationships within family, test new, eight‐subfamily classification, infer chronology evolution and invasion different regions, provide basis for future analyses trait rates diversification. Methods employed maximum‐parsimony, maximum‐likelihood, Bayesian approaches 9341 aligned bases four outgroups 90 species...
Parsimony, likelihood, and Bayesian analyses of nuclear ITS plastid trnL-F DNA sequence data are presented for the giant genus Croton (Euphorbiaceae s.s.) related taxa. Sampling comprises 88 taxa, including 78 estimated 1223 species 29 40 sections previously recognized Croton. It also includes satellite Moacroton genera formerly placed in tribe Crotoneae. all sampled segregate form a monophyletic group sister to Brasiliocroton, with exception sect. Astraea, which is reinstated Astraea. A...
Abstract Croton (Euphorbiaceae) is a large and diverse group of plants that most species‐rich in the tropics. We update infrageneric classification New World species with new evidence from phylogenetic analyses DNA sequence data all three genomes. The relationships were previously placed conflicting positions by nuclear chloroplast data, such as C. cupreatus , poecilanthus setiger are further resolved adding EMB2765 mitochondrial rps3 genes to molecular sampling. Analyses reveal an...

The phylogenetic relationships of Croton section Cyclostigma sensu Webster were examined using nuclear ribosomal ITS and plastid spacer trnL–F sequences from 48 the 63 species in group, including members four recognized subsections representing group's full morphological geographic range. two gene phylogenies concurred that is polyphyletic, with its appearing nine different clades throughout . clade retains taxonomic type about half sampled redefined here as a reduced, monophyletic ,...
Abstract Most of the arborescent Croton species in New World were treated by Webster as belonging either to C . sect. Cyclostigma Griseb. or Luntia (Neck. ex Raf.) G.L. Webster. The circumscription has been recently. In this paper we focus on , which was subdivided into two subsections, subsect. Matourenses and Cuneati Using chloroplast trnL ‐ F nuclear ITS DNA sequence data, morphology a broader sampling additional lineages, found that subsections are not closely related form distinct...
Abstract Croton alabamensis (Euphorbiaceae s.s. ) is a rare plant species known from several populations in Texas and Alabama that have been assigned to var. texensis , respectively. We performed maximum parsimony, likelihood, Bayesian analyses of DNA sequences the nuclear ribosomal internal transcribed spacer (ITS) 5.8S regions chloroplast trn L‐ F collections two varieties C. outgroup taxa. emerges alone on long branch sister section Corylocroton Cuban endemic genus Moacroton . Molecular...
The greater Caribbean region has played an important role in the early diversification of Croton L. (Euphorbiaceae s.s.). Jamaica is also to taxonomy because several earliest described species were based on material from island. Jamaican are found five distinct clades indicating that there at least separate over-water dispersal events genus jamaicensis (section Eluteria Griseb.), a new endemic limestone hills along southern coast Jamaica, and illustrated. phylogenetically most closely...
A revised assessment of Croton L. sect. Geiseleria (A. Gray) Baill. is provided. The section as now circumscribed includes 84 species ranging across warm areas the Americas. nuclear ITS phylogeny 150 accessions from 83 and a chloroplast trnL-F 89 65 were generated to confirm correct phylogenetic placement determine if any previously included in should be excluded. Seven new are described, we present taxonomic synopsis that lists all currently accepted along with their synonyms,...
Abstract Croton section Pedicellati is described, with a disjunct distribution in Mexico and South America. It recovered sister to Lamprocroton Bayesian, Maximum Likelihood, Parsimony analyses of nuclear ITS chloroplast trnL-F DNA sequence data. Two new subsections, subsection Argentini, are recognized within Lamprocroton. These well-supported clades include species bifid multifid styles, respectively. breedlovei, lepidote Pedicellati, endemic Chiapas, Mexico, described. breedlovei...
The Solanaceae family is one of the largest and well-distributed plant families in world. It contains species agricultural economical importance, such as Solanum tuberosum , melongena lycopersicum Nicotiana tabacum Capsicum annuum . In Puerto Rico, there are ≈46 which six endemic: Brunfelsia densifolia, lactea, portoricensis, Goetzea elegans, ensifolium woodburyi. Our objective was to use DNA barcoding identify including endemics, assess relationships between them. To accomplish our...
Croton is one of the most diverse genera flowering plants in Madagascar, with >150 endemic species encountered nearly all vegetation types. This study focuses on evolutionary history western Indian Ocean region (WIOR), which includes Comoro Islands and Mascarene Islands, aims to resolve relationships biogeographic genus there. We obtained nuclear ribosomal internal transcribed spacer plastid (matK, trnH-psbA trnL-F) sequence data for 71, or close half, spp. WIOR 15 other Old World seven New...
Background and Aims Wood is a major innovation of land plants, usually central component the body plan for two plant habits: shrubs trees. anatomical syndromes vary between trees, but no prior work has explicitly evaluated contingent evolution wood diversity in context these habits. Methods Phylogenetic comparative methods were used to test habit, habitat anatomy mega-diverse genus Croton (Euphorbiaceae), across largest most complete molecular phylogeny date. Key Results Plant habit are...
Cubanthus (Euphorbiaceae) has traditionally been recognized as a small genus of three similar species restricted to Cuba and Hispaniola. In this study we used DNA sequence data from the nuclear ITS chloroplast ndhF gene regions investigate its systematic position four other shrubby Euphorbia endemic Cuba: E. cubensis, helenae, munizii, podocarpifolia. The results demonstrate that all these taxa belong well-supported Antillean clade nested within also includes punicea gymnonota. For reason,...
Abstract A taxonomic key, synonymy, and a molecular phylogeny of the nine species three varieties Croton section Heptallon (Euphorbiaceae) are presented. Section Angelandra is synonymized with Heptallon, from outside North America that had been placed into these two sections shown to belong in other clades within genus. As circumscribed here, well-supported clade annual herbs subshrubs ranges central Mexico eastern United States. new combination, heptalon, made. Lectotypes designated for C....
Croton laceratoglandulosus, a new species from the dry forests of Brazilian states Piauí, Ceará, Bahia and Minas Gerais, Bolivian department Santa Cruz, is described illustrated here. Molecular sequence data demonstrate that it most closely related to taxa section Cascarilla, not sections Medea or Barhamia, which also have glandular calyces laciniate stipules.
A molecular phylogeny, morphological descriptions, species lists and a key to the sections of Croton L. (Euphorbiaceae) recognised for Australia are presented. The phylogenetic results supported recognition six sections, account 29 native Australian species. monophyly each these was highly in Bayesian maximum-likelihood analyses nuclear ITS plastid trnL–F DNA sequences, whereas their relationships other groups were less well resolved. may represent one, two or three separate arrivals...
