Classification And Biogeography Of Panicoideae (Poaceae) In The New World, Fernando O. Zuloaga, Osvaldo Morrone, Gerrit Davidse, Susan J. Pennington
Classification And Biogeography Of Panicoideae (Poaceae) In The New World, Fernando O. Zuloaga, Osvaldo Morrone, Gerrit Davidse, Susan J. Pennington
Aliso: A Journal of Systematic and Floristic Botany
Panicoideae (Poaceae) in the New World comprise 107 genera (86 native) and 1357 species (1248 native). As circumscribed herein, Panicoideae include eight tribes: Andropogoneae, Arundinelleae, Centotheceae, Gynerieae, Isachneae, Paniceae, Steyermarkochloeae, and Thysanolaeneae. The two major tribes are Andropogoneae with 230 species (16.95% of all New World panicoids), and Paniceae with 1082 species (79.73%). Andropogoneae are divided into nine subtribes (Andropogoninae, Anthistiriinae, Coicinae, Germainiinae, Ischaeminae, Rottboelliinae, Saccharinae, Sorghinae, and Tripsacinae), while Paniceae are divided into seven subtribes (Arthropogoninae, Cenchrinae, Digitariinae, Melinidinae, Panicinae, Paspalinae, and Setariinae). Brazil is the center of diversity of New World panicoids with 741 species (54.6% of all …
Phylogenetics Of Chloridoideae (Gramineae): A Preliminary Study Based On Nuclear Ribosomal Internal Transcribed Spacer And Chloroplast Trnl–F Sequences, J. Travis Columbus, Rosa Cerros-Tlatilpa, Michael S. Kinney, Maria Elena Siqueiros-Delgado, Hester L. Bell, M. Patrick Griffith, Nancy F. Refulio-Rodriguez
Phylogenetics Of Chloridoideae (Gramineae): A Preliminary Study Based On Nuclear Ribosomal Internal Transcribed Spacer And Chloroplast Trnl–F Sequences, J. Travis Columbus, Rosa Cerros-Tlatilpa, Michael S. Kinney, Maria Elena Siqueiros-Delgado, Hester L. Bell, M. Patrick Griffith, Nancy F. Refulio-Rodriguez
Aliso: A Journal of Systematic and Floristic Botany
The phylogeny of Chloridoideae (Gramineae) was inferred from parsimony analyses of DNA sequences from two genomes—the chloroplast trnL intron, trnL 3' exon, and trnL–F intergenic spacer, and the nuclear ribosomal internal transcribed spacer region (ITS1 + 5.8S + ITS2). Eighty species representing 66 chloridoid genera were sampled, including all but four of the native New World genera. Analyses of the individual and combined data sets were performed. The phylogenies were found to be highly congruent. Of the four tribes and seven subtribes of Chloridoideae sensu Clayton and Renvoize (1986) whose phylogenetic status could be tested with our …
Classification And Biogeography Of New World Grasses: Chloridoideae, Paul M. Peterson, J. Travis Columbus, Susan J. Pennington
Classification And Biogeography Of New World Grasses: Chloridoideae, Paul M. Peterson, J. Travis Columbus, Susan J. Pennington
Aliso: A Journal of Systematic and Floristic Botany
Subfamily Chloridoideae (Poaceae) in the New World includes 72 genera (61 native, 11 introduced), 678 species (607 native), and, including intraspecific taxa, 817 total taxa. The five largest genera are Muhlenbergia (147 species), Eragrostis (111), Sporobolus (76), Bouteloua (57), and Chloris (35). Three tribes are recognized in this study: Cynodonteae, Eragrostideae, and Zoysieae, with ten, three, and two subtribes, respectively. Cynodonteae, the largest tribe, comprise 58 genera and 451 species (67% of all New World chloridoids), including 25 genera (98 species, 22% of all New World Cynodonteae) with unknown affinities (incertae sedis). In Mexico, the USA, and Canada there are …
Classification And Biogeography Of New World Grasses: Anomochlooideae, Pharoideae, Ehrhartoideae, And Bambusoideae, Emmet J. Judziewicz, Lynn G. Clark
Classification And Biogeography Of New World Grasses: Anomochlooideae, Pharoideae, Ehrhartoideae, And Bambusoideae, Emmet J. Judziewicz, Lynn G. Clark
Aliso: A Journal of Systematic and Floristic Botany
Molecular data support Anomochlooideae and Pharoideae as the two most basal extant clades within Poaceae. Anomochlooideae are endemic to the New World and have two tribes and two genera including the widespread Streptochaeteae (3–4 spp.) and the critically endangered Anomochloeae (1 sp.) of coastal Bahia, Brazil. Pharoideae are pantropical with one tribe, three genera, and 14 species; all eight species of Pharus occur only in the New World. Bambusoideae and Ehrhartoideae are sister groups and together form a clade sister to Pooideae, although support for this set of relationships is low. Ehrhartoideae are a worldwide subfamily represented in the New …
A Brief Nomenclatural Review Of Genera And Tribes In Theaceae, Linda M. Prince
A Brief Nomenclatural Review Of Genera And Tribes In Theaceae, Linda M. Prince
Aliso: A Journal of Systematic and Floristic Botany
The angiosperm family Theaceae has been investigated extensively with a rich publication record of anatomical, cytological, paleontological, and palynological data analyses and interpretation. Recent developmental and molecular data sets and the application of cladistic analytical methods support dramatic changes in circumscription at the familial, tribal, and generic levels. Growing interest in the family outside the taxonomic and systematic fields warrants a brief review of the recent nomenclatural history (mainly 20th century), some of the classification systems currently in use, and an explanation of which data support various classification schemes. An abridged bibliography with critical nomenclatural references is provided.
