A Phylogeny of the Hubbardochloinae Including Tetrachaete (Poaceae: Chloridoideae: Cynodonteae)
Peterson, P.M., K. Romaschenko, and Y. Herrera Arrieta. 2020. A phylogeny of the Hubbardochloinae including Tetrachaete (Poaceae: Chloridoideae: Cynodonteae). Phytoneuron 2020-81: 1–13. Published 18 November 2020. ISSN 2153 733 A PHYLOGENY OF THE HUBBARDOCHLOINAE INCLUDING TETRACHAETE (CYNODONTEAE: CHLORIDOIDEAE: POACEAE) PAUL M. PETERSON AND KONSTANTIN ROMASCHENKO Department of Botany National Museum of Natural History Smithsonian Institution Washington, D.C. 20013-7012 [email protected]; [email protected] YOLANDA HERRERA ARRIETA Instituto Politécnico Nacional CIIDIR Unidad Durango-COFAA Durango, C.P. 34220, México [email protected] ABSTRACT The phylogeny of subtribe Hubbardochloinae is revisited, here with the inclusion of the monotypic genus Tetrachaete, based on a molecular DNA analysis using ndhA intron, rpl32-trnL, rps16 intron, rps16- trnK, and ITS markers. Tetrachaete elionuroides is aligned within the Hubbardochloinae and is sister to Dignathia. The biogeography of the Hubbardochloinae is discussed, its origin likely in Africa or temperate Asia. In a previous molecular DNA phylogeny (Peterson et al. 2016), the subtribe Hubbardochloinae Auquier [Bewsia Gooss., Dignathia Stapf, Gymnopogon P. Beauv., Hubbardochloa Auquier, Leptocarydion Hochst. ex Stapf, Leptothrium Kunth, and Lophacme Stapf] was found in a clade with moderate support (BS = 75, PP = 1.00) sister to the Farragininae P.M. Peterson et al. In the present study, Tetrachaete elionuroides Chiov. is included in a phylogenetic analysis (using ndhA intron, rpl32- trnL, rps16 intron, rps16-trnK, and ITS DNA markers) in order to test its relationships within the Cynodonteae with heavy sampling of species in the supersubtribe Gouiniodinae P.M.

If the objects are recovered, locating the rest of the Boeing 777 on the ocean floor could turn out to be harder still. And if the remains can eventually be pieced together, working out exactly what happened to flight MH370 may be the toughest job of all.

Through light microscopy analysis, we measured the size of the pollen grain, pore, and annulus from 68 species of Rio Grande do Sul. Measurements were recorded of 10 forest species and 58 grassland species, representing all tribes of the Poaceae in Rio Grande do Sul. We measured the polar, equatorial, pore, and annulus diameter. Results of statistical tests showed that arboreous forest species have larger pollen grain sizes than grassland and herbaceous forest species, and in particular there are strongly significant differences between arboreous and grassland species. Discriminant analysis identified three distinct groups representing Edited by: each vegetation type.

Responses of Plant Communities to Grazing in the Southwestern United States Department of Agriculture United States Forest Service
Responses of Plant Communities to Grazing in the Southwestern United States Department of Agriculture United States Forest Service Rocky Mountain Research Station Daniel G. Milchunas General Technical Report RMRS-GTR-169 April 2006 Milchunas, Daniel G. 2006. Responses of plant communities to grazing in the southwestern United States. Gen. Tech. Rep. RMRS-GTR-169. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 126 p. Abstract Grazing by wild and domestic mammals can have small to large effects on plant communities, depend- ing on characteristics of the particular community and of the type and intensity of grazing. The broad objective of this report was to extensively review literature on the effects of grazing on 25 plant commu- nities of the southwestern U.S. in terms of plant species composition, aboveground primary productiv- ity, and root and soil attributes. Livestock grazing management and grazing systems are assessed, as are effects of small and large native mammals and feral species, when data are available. Emphasis is placed on the evolutionary history of grazing and productivity of the particular communities as deter- minants of response. After reviewing available studies for each community type, we compare changes in species composition with grazing among community types. Comparisons are also made between southwestern communities with a relatively short history of grazing and communities of the adjacent Great Plains with a long evolutionary history of grazing. Evidence for grazing as a factor in shifts from grasslands to shrublands is considered. An appendix outlines a new community classification system, which is followed in describing grazing impacts in prior sections. -

Grasses of the Texas Hill Country: Vegetative Key and Descriptions
Hagenbuch, K.W. and D.E. Lemke. 2015. Grasses of the Texas Hill Country: Vegetative key and descriptions. Phytoneuron 2015-4: 1–93. Published 7 January 2015. ISSN 2153 733X GRASSES OF THE TEXAS HILL COUNTRY: VEGETATIVE KEY AND DESCRIPTIONS KARL W. HAGENBUCH Department of Biological Sciences San Antonio College 1300 San Pedro Avenue San Antonio, Texas 78212-4299 [email protected] DAVID E. LEMKE Department of Biology Texas State University 601 University Drive San Marcos, Texas 78666-4684 [email protected] ABSTRACT A key and a set of descriptions, based solely on vegetative characteristics, is provided for the identification of 66 genera and 160 grass species, both native and naturalized, of the Texas Hill Country. The principal characters used (features of longevity, growth form, roots, rhizomes and stolons, culms, leaf sheaths, collars, auricles, ligules, leaf blades, vernation, vestiture, and habitat) are discussed and illustrated. This treatment should prove useful at times when reproductive material is not available. Because of its size and variation in environmental conditions, Texas provides habitat for well over 700 species of grasses (Shaw 2012). For identification purposes, the works of Correll and Johnston (1970); Gould (1975) and, more recently, Shaw (2012) treat Texas grasses in their entirety. In addition to these comprehensive works, regional taxonomic treatments have been done for the grasses of the Cross Timbers and Prairies (Hignight et al. 1988), the South Texas Brush Country (Lonard 1993; Everitt et al. 2011), the Gulf Prairies and Marshes (Hatch et al. 1999), and the Trans-Pecos (Powell 1994) natural regions. In these, as well as in numerous other manuals and keys, accurate identification of grass species depends on the availability of reproductive material. -
Hans Walter Lack & Thomas Raus Hildemar Scholz
Fl. Medit. 22: 233-244 doi: 10.7320/FlMedit22.233 Version of Record published online on 28 December 2012 Hans Walter Lack & Thomas Raus Hildemar Scholz (1928 – 2012) Hildemar Scholz, aged 84, passed away on 5 June 2012 as a consequence of a bad fall he had suffered at home a few weeks earlier. He was a world authority on grasses, the adventive flora of Europe, and rust fungi from central Europe. From 1964 until his retire- ment in 1993 he was a member of staff of the Botanic Garden and Botanical Museum Berlin-Dahlem, rising from scientific collaborator to one of the directors at this institution. Hildemar was a born plant-collector active all over Europe, in North and West Africa with a special interest in grasses and the rust fungi parasitizing them. Born on 27 May 1928 in Berlin into a family of protestant clergymen Hildemar Scholz remained both in language and manners very much a Berliner, in the true and best sense of the word, and never ever considered leaving his home town, even during the many diffi- cult years this city encountered in the last century. Having belatedly finished his school training because of the Second World War in 1947, he tried to get enrolled at Berlin University, subsequently renamed Humboldt University, in the Soviet sector of the city, but was rejected – probably because his father was a clergyman. Hildemar had more success at the newly founded Free University in the American sector of Berlin, where he got admit- ted in 1949 and chose biology as his subject. -
Vascular Flora of Gus Engeling Wildlife Management Area, Anderson County, Texas
2003SOUTHEASTERN NATURALIST 2(3):347–368 THE VASCULAR FLORA OF GUS ENGELING WILDLIFE MANAGEMENT AREA, ANDERSON COUNTY, TEXAS 1 2,3 2 JASON R. SINGHURST , JAMES C. CATHY , DALE PROCHASKA , 2 4 5 HAYDEN HAUCKE , GLENN C. KROH , AND WALTER C. HOLMES ABSTRACT - Field studies in the Gus Engeling Wildlife Management Area, which consists of approximately 4465.5 ha (11,034.1 acres) of the Post Oak Savannah of Anderson County, have resulted in an annotated checklist of the vascular flora corroborating its remarkable species richness. A total of 930 taxa (excluding family names), belonging to 485 genera and 145 families are re- corded. Asteraceae (124 species), Poaceae (114 species), Fabaceae (67 species), and Cyperaceae (61 species) represented the largest families. Six Texas endemic taxa occur on the site: Brazoria truncata var. pulcherrima (B. pulcherrima), Hymenopappus carrizoanus, Palafoxia reverchonii, Rhododon ciliatus, Trades- cantia humilis, and T. subacaulis. Within Texas, Zigadenus densus is known only from the study area. The area also has a large number of species that are endemic to the West Gulf Coastal Plain and Carrizo Sands phytogeographic distribution patterns. Eleven vegetation alliances occur on the property, with the most notable being sand post oak-bluejack oak, white oak-southern red oak-post oak, and beakrush-pitcher plant alliances. INTRODUCTION The Post Oak Savannah (Gould 1962) comprises about 4,000,000 ha of gently rolling to hilly lands that lie immediately west of the Pineywoods (Timber belt). Some (Allred and Mitchell 1955, Dyksterhuis 1948) consider the vegetation of the area as part of the deciduous forest; i.e., burned out forest that is presently regenerating.
