A revision of Geonoma (Arecaceae)
<p>A taxonomic revision and phylogeny of the neotropical palm genus Geonoma based on morphological data and morphometric methods was carried out. 4990 herbarium specimens were scored for 44 qualitative variables and 27 quantitative variables. Qualitative variables were divided into 30 characters and 14 traits. Using the phylogenetic species concept, characters were used to recognize 68 species. These are widely distributed from southern Mexico to Bolivia and Paraguay, and reach the Lesser Antilles and Hispaniola. Analysis of each species for traits, geographic distribution, and quantitative variables led to recognition of 90 subspecies in 18 species, giving a total of 140 taxa. Twelve new species (G. bernalii, G. concinnoidea, G. deneversii, G. dindoensis, G. fosteri, G. galeanoae, G. gentryi, G. operculata, G. peruviana, G. sanmartinensis, G. schizocarpa, G. venosa) and 33 new subspecies (G. brongniartii subsp. pascoensis, G. concinna subsp. simplex, G. concinnoidea subsp. coclensis, G. concinnoidea subsp. jefensis, G. congesta subsp. osensis, G. cuneata subsp. guanacastensis, G. cuneata subsp. indivisa, G. cuneata subsp. minor, G. cuneata subsp. rubra, G. deversa subsp. belizenesis, G. deversa subsp. peninsularis, G. deversa subsp. quadriflora, G. ferruginea subsp. nicaraguensis, G. lehmannii subsp. corrugata, G. longivaginata subsp. copensis, G. longivaginata subsp. sanblasensis, G. longivaginata subsp. vallensis, G. maxima subsp. dispersa, G. maxima subsp. multiramosa, G. maxima subsp. sigmoidea, G. pohliana subsp. linharenseis, G. pohliana subsp. rodriguesii, G. pohliana subsp. unaensis, G. stricta subsp. antioquiensis, G. stricta subsp. bracteata, G. stricta subsp. divaricata, G. stricta subsp. pendula, G. stricta subsp. pliniana, G. stricta subsp. quibdoensis, G. stricta subsp. submontana, G. undata subsp. tacarcunensis, G. undata subsp. tumucensis, G. undata subsp. venezuelana) are described. Forty-one new combinations are made. Several of the most variable species are considered to be species complexes and are divided into morphotypes—groups of similar specimens with no formal taxonomic status. Nomenclature, descriptions and distribution maps are provided for each species and subspecies. Images of the type specimens of all new taxa are also provided. A phylogenetic analysis, using the same 30 characters used for the taxonomic revision was carried out using parsimony analysis. A sample tree and consensus tree are shown and a discussion is given of the various clades.<br> </p>
A revision of Leopoldinia (Arecaceae)
<p>A taxonomic revision of the Neotropical palm genus Leopoldinia based on morphological data and morphometric methods was carried out. One hundred and sixteen herbarium specimens were scored for seven qualitative and 24 quantitative variables. Qualitative variables were divided into six characters and one trait. Using the Phylogenetic Species Concept, the six characters were used to recognize three species. These are widely distributed in the central Amazon region of Brazil and adjacent Venezuela and Colombia. Nomenclature, descriptions, illustrations, and distribution maps are provided for each taxon.</p>
A revision of Desmoncus (Arecaceae)
<p>A taxonomic revision of the Neotropical palm genus Desmoncus based on morphological data and morphometric methods was carried out. Eight hundred and fifty-one herbarium specimens were scored for 16 qualitative variables and 16 quantitative variables. Qualitative variables were divided into 15 characters and one trait. Using the Phylogenetic Species Concept, characters were applied to recognize 24 species. These are widely distributed in Central and South America from southern Mexico to Bolivia and Paraguay, and to Trinidad, Tobago, and the Lesser Antilles. Analysis of each species for geographic distribution and quantitative variables led to recognition of 9 subspecies in two of the species, giving a total of 31 taxa. Seven new species (D. kunarius, D. interjectus, D. loretanus, D. madrensis, D. moorei, D. obovoideus, D. osensis) and two new subspecies (D. horridus subsp. occidentalis, D. mitis subsp. ecirratus) are described. Five new combinations are made. One of the most variable species is considered to be a species complex and is divided into morphotypes: groups of similar specimens without formal taxonomic status. Nomenclature, descriptions, and distribution maps are provided for each species and subspecies. Images of type specimens of all new taxa are also given.</p>
A revision of Pholidostachys (Arecaceae)
<p>A taxonomic revision of the neotropical palm genus Pholidostachys based on morphological data and morphometric methods was carried out. Two hundred and eighty-eight herbarium specimens were scored for five qualitative variables and 25 quantitative variables. Qualitative variables were divided into four characters and one trait. Using the Phylogenetic Species Concept, characters were used to recognize seven species. These are widely distributed in Central and northwestern South America from Nicaragua to Colombia, Ecuador, Peru, and Brazil. Analysis of each species for geographic distribution and quantitative variables led to recognition, in one species, of two subspecies, giving a total of eight taxa. Four new species (P. amazonensis, P. occidentalis, P. panamensis, P. sanluisensis) are described. Two new combinations are made. Nomenclature, descriptions, and distribution maps are provided for each species and subspecies. Images of the type specimens of all new taxa are also provided.</p>

A revision of Calamus (Arecaceae, Calamoideae, Calameae, Calaminae)
<p>A revision of Calamus was carried out based on morphological data.

Analysis of quantitative variables and geographic distributions resulted in the division of 11 species into 36 subspecies. Eight species were considered to be ochlospecies (C. erioacanthus, C. inermis, C. javensis, C. melanochaetes, C. micranthus, C. moseleyanus, C. plicatus, C. siphonospathus). Nomenclature, descriptions, and distribution maps are provided for all species. Images of the type specimens of all new species are provided as well as images of most qualitative variables.

Data from: Phylogenomic analyses of Sabal (Arecaceae) species relationships using targeted sequence capture
With the increasing availability of high-throughput sequencing, phylogenetic analyses are no longer constrained by the limited availability of a few loci. Here, we describe a sequence capture methodology, which we used to collect data for analyses of diversification within Sabal (Arecaceae), a palm genus native to the south-eastern USA, Caribbean, Bermuda and Central America. RNA probes were developed and used to enrich DNA samples for putatively low copy nuclear genes and the plastomes for all Sabal species and two outgroup species. Sequence data were generated on an Illumina MiSeq sequencer and target sequences were assembled using custom workflows. Both coalescence and supermatrix analyses of 133 nuclear genes were used to estimate species trees relationships. Plastid genomes were also analysed, yielding generally poor resolution with regard to species relationships. Species relationships described in both nuclear gene and plastome sequences largely reflect the biogeography of the group and, to a lesser extent, previous morphology-based hypotheses. Beyond the biological implications, this research validates a high-throughput methodology for generating a large number of genes for coalescence-based phylogenetic analyses in plant lineages.
