Ii \ T MEXICAN GRASSES in the UNITED STATES NATIONAL
■ . ~+j-,r?7-w- - i i - . \ t MEXICAN GRASSES IN THE UNITED STATES NATIONAL HERBARIUM. By A. S, Hitchcock INTRODUCTION. The following list of grasses, based entirely upon specimens in the United States National Herbarium, is a preliminary paper, in which the scattered data upon Mexican grasses have been brought together and arranged in a convenient form. The species included have been accepted, for the most part, in their traditional sense. It has been impracticable to examine the types of many of the earlier described species since these specimens are located in European herbaria. For this reason the synonymy has been confined mostly to those names that could be fixed by an examination of American types, or concerning the application of which there was little doubt. The largest number of unidentified names are found in Fournier's work on Mexican grasses.1 This results from the incomplete or unsatis- factory descriptions and from the fact that the specimens cited under a given species either may not agree with the diagnosis, or may belong to two or more species, at least in different herbaria. An examination of the original specimens will undoubtedly lead to the identification of the greater part of these names. There are several specimens that have been omitted from the list because they have not been identified and are apparently unde- scribed species. They belong to genera, however, that are much in need of critical revision and further study of them is deferred for the present. In subsequent articles it is hoped to work out the classifi- cation of the tropical American grasses upon a type basis KEY TO THE GENEBA. -

Retallack 2021 Coal Balls

Two distinct kinds of coal balls are here recognized in both Holocene Histosol and Pennsylvanian calcareous Histosols. Respirogenic calcite coal balls have arrays of calcite δ18O and δ13C like Carbon isotopes those of desert soil calcic horizons reflecting isotopic composition of CO2 gas from an aerobic microbiome. Permineralization Methanogenic calcite coal balls in contrast have invariant δ18O for a range of δ13C, and formed with anaerobic microbiomes in soil solutions with bicarbonate formed by methane oxidation and sugar fermentation. Respiro genic coal balls are described from Holocene peats in Eight Mile Creek South Australia, and noted from Carboniferous coals near Penistone, Yorkshire. Methanogenic coal balls are described from Carboniferous coals at Berryville (Illinois) and Steubenville (Ohio), Paleocene lignites of Sutton (Alaska), Eocene lignites of Axel Heiberg Island (Nunavut), Pleistocene peats of Konya (Turkey), and Holocene peats of Gramigne di Bando (Italy). Soils and paleosols with coal balls are neither common nor extinct, but were formed by two distinct soil microbiomes. 1. Introduction and Royer, 2019).

Mineralogy of Non-Silicified Fossil Wood
Article Mineralogy of Non-Silicified Fossil Wood George E. Mustoe Geology Department, Western Washington University, Bellingham, WA 98225, USA; [email protected]; Tel: +1-360-650-3582 Received: 21 December 2017; Accepted: 27 February 2018; Published: 3 March 2018 Abstract: The best-known and most-studied petrified wood specimens are those that are mineralized with polymorphs of silica: opal-A, opal-C, chalcedony, and quartz. Less familiar are fossil woods preserved with non-silica minerals. This report reviews discoveries of woods mineralized with calcium carbonate, calcium phosphate, various iron and copper minerals, manganese oxide, fluorite, barite, natrolite, and smectite clay. Regardless of composition, the processes of mineralization involve the same factors: availability of dissolved elements, pH, Eh, and burial temperature. Permeability of the wood and anatomical features also plays important roles in determining mineralization. When precipitation occurs in several episodes, fossil wood may have complex mineralogy. Keywords: fossil wood; mineralogy; paleobotany; permineralization 1. Introduction Non-silica minerals that cause wood petrifaction include calcite, apatite, iron pyrites, siderite, hematite, manganese oxide, various copper minerals, fluorite, barite, natrolite, and the chromium- rich smectite clay mineral, volkonskoite. This report provides a broad overview of woods fossilized with these minerals, describing specimens from world-wide locations comprising a diverse variety of mineral assemblages. Data from previously-undescribed fossil woods are also presented. The result is a paper that has a somewhat unconventional format, being a combination of literature review and original research. In an attempt for clarity, the information is organized based on mineral composition, rather than in the format of a hypothesis-driven research report. -

Fern Classification
16 Fern classification ALAN R. SMITH, KATHLEEN M. PRYER, ERIC SCHUETTPELZ, PETRA KORALL, HARALD SCHNEIDER, AND PAUL G. WOLF 16.1 Introduction and historical summary / Over the past 70 years, many fern classifications, nearly all based on morphology, most explicitly or implicitly phylogenetic, have been proposed. The most complete and commonly used classifications, some intended primar• ily as herbarium (filing) schemes, are summarized in Table 16.1, and include: Christensen (1938), Copeland (1947), Holttum (1947, 1949), Nayar (1970), Bierhorst (1971), Crabbe et al. (1975), Pichi Sermolli (1977), Ching (1978), Tryon and Tryon (1982), Kramer (in Kubitzki, 1990), Hennipman (1996), and Stevenson and Loconte (1996). Other classifications or trees implying relationships, some with a regional focus, include Bower (1926), Ching (1940), Dickason (1946), Wagner (1969), Tagawa and Iwatsuki (1972), Holttum (1973), and Mickel (1974). Tryon (1952) and Pichi Sermolli (1973) reviewed and reproduced many of these and still earlier classifica• tions, and Pichi Sermolli (1970, 1981, 1982, 1986) also summarized information on family names of ferns. Smith (1996) provided a summary and discussion of recent classifications. With the advent of cladistic methods and molecular sequencing techniques, there has been an increased interest in classifications reflecting evolutionary relationships. Phylogenetic studies robustly support a basal dichotomy within vascular plants, separating the lycophytes (less than 1 % of extant vascular plants) from the euphyllophytes (Figure 16.l; Raubeson and Jansen, 1992, Kenrick and Crane, 1997; Pryer et al., 2001a, 2004a, 2004b; Qiu et al., 2006). Living euphyl• lophytes, in turn, comprise two major clades: spermatophytes (seed plants), which are in excess of 260 000 species (Thorne, 2002; Scotland and Wortley, Biology and Evolution of Ferns and Lycopliytes, ed. -

MUHLENBERGIA TARAHUMARA (POACEAE: CHLORIDOIDEAE: CYNODONTEAE: MUHLENBERGIINAE), A NEW SPECIES FROM CHIHUAHUA, MEXICO Paul M. Peterson J. Travis Columbus Department of Botany Rancho Santa Ana Botanic Garden and National Museum of Natural History Claremont Graduate University Smithsonian Institution 1500 North College Avenue Washington, DC 20013-7012, U.S.A. Claremont, California 91711-3157, U.S.A. [email protected] [email protected] ABSTRACT Muhlenbergia tarahumara P.M. Peterson & Columbus, sp. nov., is described and illustrated. The new species occurs on rocky slopes, ridgetops, and white-tuff rock outcrops in the Sierra Madre Occidental and is known only from the municipality of Guachochi in Chi- huahua, Mexico. Based on morphological and phylogenetic analysis of plastid and nuclear DNA sequence data, we conclude that the new species is sister to the Aegopogon clade that is nested within a clade of species in Muhlenbergia subgen. Muhlenbergia. Muhlenbergia tarahumara differs from Aegopogon cenchroides by having panicle branches 5−13 per culm, each with two terminal, one-flowered spikelets; glumes 3−5.8 mm long, shorter than the lemma and narrowly lanceolate; lemmas 3.6−7.3 mm long, lanceolate; paleas 3−4.6 mm long; and anthers 2.2−2.8 mm long, yellowish orange. RESUMEN Se describe e ilustra Muhlenbergia tarahumara P.M. Peterson & Columbus, sp. nov. La nueva especie habita en cuestas rocosas, en cimas de cerros y en afloramientos de tobas volcánicas blancas en la Sierra Madre Occidental y se conoce solamente en del municipio de Guachochi en Chihuahua, México. Basados en los análisis morfológicos y filogenéticos de las secuencias de ADN plastidial y nuclear, podemos concluir que la nueva especie es hermana del clado Aegopogon, el cual se encuentra anidado en el clado de especies de Muhlen- bergia subgen.
