Preliminary analyses of the ceramics, lithics, botanical and faunal material are presented in a cultural sequence beginning at 9,480 B.C. The botanical remains recovered from the site are inventoried and several species are subjected to preliminary morphometric analyses in order to characterize the assemblage, and assess changes in plant phenotypes through time. The operation of "directional" (artificial) selection is evident at the site for several species, including avocado (Persea americana), squash (Cucurbita sp., cf. C. pepo), and bottle gourd (Lagenaria siceraria). While varieties of squashes may have been cultivated in the Archaic, clearly domesticated maize and beans appear to have been introduced in the Formative. However, stratigraphic disconformities in the period of c. 5,000 – 2,000 B.C., may bias this conclusion. From early in the sequence, botanical diversity is high, despite changing subsistence specialization and generalization evident in other artifact assemblages. Many undomesticated species are utilized prehistorically and are not lost from the diet despite the intensification of field-based food production of domesticated species. An emphasis is placed on suites of plants, both wild and domesticated, annual and perennial, whose use is integrated through time El Gigante. Together these subsistence systems afforded flexible, energetically efficient and risk minimizing choices to prehistoric foragers. Low level food production is evident as early as the Archaic period. Tree crops were one focus of subsistence practices. The augmentation and management of perennials is inferred from their consistency and prominence in the archaeological record. However, there is also evidence for the use of annual grasses during this time. The data invites further investigation into the landscape level paleoecological past around El Gigante. iii Table of Contents List of

  • 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.

    Article An Updated Infrageneric Classification of the North American Oaks (Quercus Subgenus Quercus): Review of the Contribution of Phylogenomic Data to Biogeography and Species Diversity Paul S. Manos 1,* and Andrew L. Hipp 2 1 Department of Biology, Duke University, 330 Bio Sci Bldg, Durham, NC 27708, USA 2 The Morton Arboretum, Center for Tree Science, 4100 Illinois 53, Lisle, IL 60532, USA; [email protected] * Correspondence: [email protected] Abstract: The oak flora of North America north of Mexico is both phylogenetically diverse and species-rich, including 92 species placed in five sections of subgenus Quercus, the oak clade centered on the Americas. Despite phylogenetic and taxonomic progress on the genus over the past 45 years, classification of species at the subsectional level remains unchanged since the early treatments by WL Trelease, AA Camus, and CH Muller. In recent work, we used a RAD-seq based phylogeny including 250 species sampled from throughout the Americas and Eurasia to reconstruct the timing and biogeography of the North American oak radiation. This work demonstrates that the North American oak flora comprises mostly regional species radiations with limited phylogenetic affinities to Mexican clades, and two sister group connections to Eurasia. Using this framework, we describe the regional patterns of oak diversity within North America and formally classify 62 species into nine major North American subsections within sections Lobatae (the red oaks) and Quercus (the Citation: Manos, P.S.; Hipp, A.L. An Quercus Updated Infrageneric Classification white oaks), the two largest sections of subgenus .

Agropolis, BP The genus Attalea (Arecaceae) is distributed in continental habitats of the Neotropical region and in some 64501, 34394 Montpellier Cedex 5, France. Caribbean islands. Life forms of Attalea species vary from small acaulescent palms to tall and massive palms, always solitary. The ecological range of the genus encompasses most of the Neotropical ecosystems, from coastal sand dunes to sub-Andean forests up to 1600 m in elevation, lowland wet to dry forests, savannas, swamps, etc. The taxonomy of the genus has been poorly understood due to conflicting genus and species concepts that exist since the last decades. Taxonomical problems have been caused by the lack of adequate material, especially species of large size, loss of many types and difficulties in interpreting hybrids. In this article, I review the most recent taxonomic literature on Attalea. The number of species in Attalea varies from 29 to 67 depending on different authors, with a maximum estimate of 73 species when combining the revised publications. There is a consensus for the validity of 20 species among modern palm taxonomists. The most conflicting species or group of species are discussed in detail as well as the taxonomic significance of some characters such as the pattern of insertion of staminate flowers on rachillae, insertion of pinnae on rachis, and arrangement of fibrous strands in the endocarp.
