Types of American Grasses
z LIBRARY OF Si AS-HITCHCOCK AND AGNES'CHASE 4: SMITHSONIAN INSTITUTION UNITED STATES NATIONAL MUSEUM oL TiiC. CONTRIBUTIONS FROM THE United States National Herbarium Volume XII, Part 3 TXE&3 OF AMERICAN GRASSES . / A STUDY OF THE AMERICAN SPECIES OF GRASSES DESCRIBED BY LINNAEUS, GRONOVIUS, SLOANE, SWARTZ, AND MICHAUX By A. S. HITCHCOCK z rit erV ^-C?^ 1 " WASHINGTON GOVERNMENT PRINTING OFFICE 1908 BULLETIN OF THE UNITED STATES NATIONAL MUSEUM Issued June 18, 1908 ii PREFACE The accompanying paper, by Prof. A. S. Hitchcock, Systematic Agrostologist of the United States Department of Agriculture, u entitled Types of American grasses: a study of the American species of grasses described by Linnaeus, Gronovius, Sloane, Swartz, and Michaux," is an important contribution to our knowledge of American grasses. It is regarded as of fundamental importance in the critical sys- tematic investigation of any group of plants that the identity of the species described by earlier authors be determined with certainty. Often this identification can be made only by examining the type specimen, the original description being inconclusive. Under the American code of botanical nomenclature, which has been followed by the author of this paper, "the nomenclatorial t}rpe of a species or subspecies is the specimen to which the describer originally applied the name in publication." The procedure indicated by the American code, namely, to appeal to the type specimen when the original description is insufficient to identify the species, has been much misunderstood by European botanists. It has been taken to mean, in the case of the Linnsean herbarium, for example, that a specimen in that herbarium bearing the same name as a species described by Linnaeus in his Species Plantarum must be taken as the type of that species regardless of all other considerations. -

REINWARDTIA published by Herbarium Bogoriense - LBN. Bogor Vol. 10, Part 2, pp. 115 — 117 (1085) AEGOPOGON (GRAMINEAE) IN MALESIA J. F. VELDKAMP Kijksherbarium; Leiden, the Netherlands ABSTRACT AeyopoyoiL ceucliroides Willd. var. cenchroides is recorded for the first time from Malesian area based on a collection from Mt. Michael (Papuu New Guinea). A description is provided. ABSTKAK Aegopogou cenchroides Willd. var. emtchrvkles direkam untuk perfcamu kali dari Kawasan Malesia, berdasarkan koleksi dari Gummg Michael 'Papua Nugini). Sebuah pertelaan disajikan. In June 1979 Mr. K. Kerenga, Lae, Papua New Guinea, visited the summit of Mt, Michael, ca. 3750 m high. Among his collections was a curious grass (LAE 74443), .said to cover large areas by sprawling, which has turned out to be Aegopogon cenchroides Willd. var. cenchroides. Neither the species, not the genus was so far known from Malesia, and as I think existing descriptions may not always be within reach of Malesian botanists a short generico-specific description is given here based on the New Guinea collection. The plant is especially conspicuous for the one-sided panicle with paired, much-bristled spikelets that drop off as small burs. The genus of three species is restricted to subtropical America, while our species occurs from Northern Mexico to Bolivia and Venezuela. This distribution would seem to make introduction hardly likely on a mountain only rarely visited by local people and even less outsiders. The latter would be mainly Australian, but the genus has not yet been reported from that continent (Simon in Techn. Bull. Bot. Br. Dept. Prim. Industr., Brisbane 3: 1—89. -
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.

EDWARDS† andCHRISTOPHER J. STILL‡§ *National Center for Ecological Analysis and Synthesis (NCEAS), 735 State Street, Suite 300, Santa Barbara, CA 93101, USA, †Department of Ecology and Evolutionary Biology, Brown University, Providence, RI 02912, USA, ‡Department of Geography, University of California, Santa Barbara, CA 93106-4060, USA, §Forest Ecosystems and Society, Oregon State University, 321 Richardson Hall, Corvallis, OR 97331-5752, USA Abstract A number of studies have demonstrated the ecological sorting of C3 and C4 grasses along temperature and moisture gradients. However, previous studies of C3 and C4 grass biogeography have often inadvertently compared species in different and relatively unrelated lineages, which are associated with different environmental settings and distinct adaptive traits. Such confounded comparisons of C3 and C4 grasses may bias our understanding of ecological sorting imposed strictly by photosynthetic pathway. Here, we used MaxEnt species distribution modeling in combination with satellite data to understand the functional diversity of C3 and C4 grasses by comparing both large clades and closely related sister taxa. Similar to previous work, we found that C4 grasses showed a preference for regions with higher temperatures and lower precipitation compared with grasses using the C3 pathway. However, air temperature differences were smaller (2 °C vs. 4 °C) and precipitation and % tree cover differences were larger (1783 mm vs. 755 mm, 21.3% vs. 7.7%, respectively) when comparing C3 and C4 grasses within the same clade vs. -

A Vegetation Map of the Valles Caldera National Preserve, New
______________________________________________________________________________ A Vegetation Map of the Valles Caldera National Preserve, New Mexico ______________________________________________________________________________ A Vegetation Map of Valles Caldera National Preserve, New Mexico 1 Esteban Muldavin, Paul Neville, Charlie Jackson, and Teri Neville2 2006 ______________________________________________________________________________ SUMMARY To support the management and sustainability of the ecosystems of the Valles Caldera National Preserve (VCNP), a map of current vegetation was developed. The map was based on aerial photography from 2000 and Landsat satellite imagery from 1999 and 2001, and was designed to serve natural resources management planning activities at an operational scale of 1:24,000. There are 20 map units distributed among forest, shrubland, grassland, and wetland ecosystems. Each map unit is defined in terms of a vegetation classification that was developed for the preserve based on 348 ground plots. An annotated legend is provided with details of vegetation composition, environment, and distribution of each unit in the preserve. Map sheets at 1:32,000 scale were produced, and a stand-alone geographic information system was constructed to house the digital version of the map. In addition, all supporting field data was compiled into a relational database for use by preserve managers. Cerro La Jarra in Valle Grande of the Valles Caldera National Preserve (Photo: E.

This is the second largest family in the flora area after Asteraceae. A total of 97 taxa in 46 genera of grasses are included in this publication, which includes ones established and reproducing in the modern flora (86 taxa in 43 genera), some occurring at the margins of the flora area or no long known from the area, and ice age fossils. At least 28 taxa are known by fossils recovered from packrat middens, five of which have not been found in the modern flora: little barley ( Hordeum pusillum ), cliff muhly ( Muhlenbergia polycaulis ), Paspalum sp., mutton bluegrass ( Poa fendleriana ), and bulb panic grass ( Zuloagaea bulbosa ). Non-native grasses are represented by 27 species, or 28% of the modern grass flora. -
