Classification And Biogeography Of Panicoideae (Poaceae) In The New World, Fernando O. Zuloaga, Osvaldo Morrone, Gerrit Davidse, Susan J. Pennington Dec 2007

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 …


Classification And Biogeography Of New World Grasses: Chloridoideae, Paul M. Peterson, J. Travis Columbus, Susan J. Pennington Dec 2007

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 Dec 2007

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 …


Juniperus Oxycedrus L. Subsp. Oxycedrus Var. Spilinanus Yalt., Eliçin & Terzioğlu: A New Variety From Turkey, Fai̇k Yaltirik, Gökhan Eli̇çi̇n, Sali̇h Terzi̇oğlu Jan 2007

Juniperus Oxycedrus L. Subsp. Oxycedrus Var. Spilinanus Yalt., Eliçin & Terzioğlu: A New Variety From Turkey, Fai̇k Yaltirik, Gökhan Eli̇çi̇n, Sali̇h Terzi̇oğlu

Turkish Journal of Botany

A new variety from Turkey is described and illustrated: Juniperus oxycedrus L. subsp. oxycedrus var. spilinanus Yalt., Eliçin & Terzioğlu. This variety grows in forest clearings of Pinus brutia Ten. and P. nigra J.F.Arnold subsp. nigra var. caramanica (Loudon) Rehder, and on stony slopes (800-1400 m) in Spildağı National Park, Manisa (B1) in West Anatolia. Its diagnostic morphological characters are discussed.


The Phytoplankton Community (Except Bacillariophyceae) Of Lake Abant (Bolu, Turkey), Abuzer Çelekli̇, Olcay Obali, Okan Külköylüoğlu Jan 2007

The Phytoplankton Community (Except Bacillariophyceae) Of Lake Abant (Bolu, Turkey), Abuzer Çelekli̇, Olcay Obali, Okan Külköylüoğlu

Turkish Journal of Botany

A total of 162 phytoplankton species found monthly from 3 littoral and 2 vertical stations between June 2003 and June 2005 were identified from Lake Abant (Bolu, Turkey). Some species, such as Trachelomonas volvocina Ehrenberg, Cryptomonas ovata Ehrenberg, and Ceratium hirundinella (Müller) Dujardin showed frequent occurrence almost every month, but others had specific seasonality. Phytoplankton composition of this lake was dominated by Chlorophyta, accounting for about 58.6% of the species richness. Phytoplankton composition in Lake Abant included many new reported (> 30) taxa for the algal flora of Turkey.


The Taxonomy And Variation Of Leaf Anatomical Characters In The Genus Aegilops L. (Poaceae) In Iran, Navaz Kharazian Jan 2007

The Taxonomy And Variation Of Leaf Anatomical Characters In The Genus Aegilops L. (Poaceae) In Iran, Navaz Kharazian

Turkish Journal of Botany

This study concerns the evaluation of leaf anatomical characters (7 qualitative and 12 quantitative characters) among 26 accessions of the Aegilops L. species. The results of this study showed that the anatomical characters have high variation in the width of stomata, the number of long cells in the adaxial epidermis, the number of short cells in the abaxial epidermis, the number of stomata in the abaxial epidermis, the occurrence of prickles in the adaxial epidermis, and the width of phloem cells. The variations in anatomical characters were related to the cold and warm areas of Iran and commonly occurred among …

Macrofungi Of Honaz Mountain (Denizli), Kudret Gezer, Mustafa Işiloğlu, Azi̇z Türkoğlu, Hakan Alli

Turkish Journal of Botany

Specimens of macrofungi were collected from localities on Honaz Mountain (Denizli) in 2005 and 2006, particularly during autumn and spring. Field and laboratory studies revealed a total of 109 taxa belonging to 64 genera, 32 families and 2 classes. Six taxa belong to Ascomycetes and 103 to Basidiomycetes.


A Morphological Investigation Of Colchicum L. (Liliaceae) Species In The Mediterranean Region In Turkey, Olcay Di̇nç Düşen, Hüseyi̇n Sümbül Jan 2007

A Morphological Investigation Of Colchicum L. (Liliaceae) Species In The Mediterranean Region In Turkey, Olcay Di̇nç Düşen, Hüseyi̇n Sümbül

Turkish Journal of Botany

The morphological features of Colchicum L. species were studied based on samples collected from the Mediterranean region in Turkey between 2000 and 2004. Typifications, synonym lists, descriptions, ecology, and phytogeography are provided for all Colchicum species and relationships to similar species are discussed. New features were determined that were not previously given in descriptions of Colchicum species in the Flora of Turkey, and useful identification keys (for both flowering material and leafing-fruiting material) were prepared for all Colchicum species in the Mediterranean region of Turkey.
