  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.

  • Historical Biogeography and Character Evolution of Cistaceae (Malvales) Based on Analysis of Plastid Rbcl and Trnl-Trnf Sequences Beatriz Guzma´Nã, Pablo Vargas
    ARTICLE IN PRESS Organisms, Diversity & Evolution 9 (2009) 83–99 www.elsevier.de/ode Historical biogeography and character evolution of Cistaceae (Malvales) based on analysis of plastid rbcL and trnL-trnF sequences Beatriz Guzma´nÃ, Pablo Vargas Real Jardı´n Bota´nico – CSIC, Plaza de Murillo 2, 28014-Madrid, Spain Received 22 October 2008; accepted 21 January 2009 Abstract Cistaceae consist of eight genera and about 180 species. Some taxonomic limits and relationships within the family remain unresolved when relying exclusively on morphological data. In the present study, a phylogeny was reconstructed and divergence times were estimated for 47 species representing various groups in Cistaceae and using coding (rbcL) and spacer (trnL-trnF) sequences of plastid DNA. The firm set of morphological synapomorphies that indicates the monophyly of the family is supported by both Bayesian and parsimony analyses. Five major lineages can be distinguished within the Cistaceae: (1) an early-diverging lineage containing Fumana species; (2) the New World Lechea clade; (3) the Helianthemum s.l. clade, containing two sister groups, one of species from the New World (Crocanthemum, Hudsonia) and the other with species from the Old World (Helianthemum s. str.); (4) the Tuberaria clade; and (5) a cohesive complex consisting of Halimium and Cistus species. Evolutionary shifts in 12 key characters of Cistaceae are inferred based on the most plausible phylogenetic hypothesis. Reconstructing the evolution of ovule position supports anatropous ovules as the ancestral condition within the Cistaceae, which is currently found only in Fumana. The Cistus-Halimium assemblage is consistently obtained as a natural clade and further supported by a cytological synapomorphy (chromosome number n ¼ 9).

  • Phragmites Management Sourcebook for the Tidal Hudson River(And Beyond)
    Kiviat - Hudsonia Phragmites Management Sourcebook for the Tidal Hudson River (and beyond) Erik Kiviat Hudsonia Ltd., P.O. Box 5000, Annandale NY 12504-5000 USA Report to the Hudson River Foundation, Grant 012/00A 3 November 2006 © 2006 Erik Kiviat Abstract. Phragmites australis (common reed) is an invasive marsh plant spreading in many wetlands on and near the tidal Hudson River. Phragmites is generally considered a pest with low value to wildlife and threatening rare plants, but scientific documentation is ambivalent. Some organisms are favored by Phragmites invasion and some are not. Phragmites appears to have considerable value for water quality amelioration and soil stabilization. Ecological functions of Phragmites vary greatly depending on site and stand factors. Important site factors include depth and duration of flooding, salinity, soil organic matter content, and microtopography; important stand factors include Phragmites height, density, dominance, prevalence of inflorescences (tassels), vine loads, presence of trees or shrubs, stand size, and interspersion of Phragmites patches with other plant communities. Phragmites is often encouraged by, and a symptom of, underlying problems, such as siltation, nutrient loading, and hydrological alteration. Yet Phragmites does not necessarily indicate poor habitat quality. Many restoration and management projects seek to remove Phragmites despite poor understanding of its ecology, the nontarget impacts of removal, and the sustainability of alternate species. I conducted a review and synthesis of information pertinent to the ecology and management of Phragmites on the Hudson River estuary and in nearby areas. This synthesis is unique in focusing on the Hudson River, considering a wide taxonomic and functional range of Phragmites impacts, and including extensive published and unpublished data and observations.

  • STABLE DUNE BARREN (BEACH HEATHER SUBTYPE) Concept: Stable Dune Barrens Are Sparsely- to Moderately-Vegetated Communities Of
    STABLE DUNE BARREN (BEACH HEATHER SUBTYPE) Concept: Stable Dune Barrens are sparsely- to moderately-vegetated communities of inactive dunes and high sand flats of barrier island interiors, not dominated by Uniola paniculata, Ammophila breviligulata, or Schizachyrium littorale. While Schizachyrium littorale and other Dune Grass species may be present in small amounts, the vegetation is predominantly species not found in Dune Grass communities. The community often includes substantial bare sand, but also may include open or patchy cover of woody vines, shrubs, and even trees. It occurs on broader barrier islands, in association with Maritime Evergreen Forest and Maritime Shrub. The Beach Heather Subtype covers examples from Bodie Island northward, where Hudsonia tomentosa is a prominent component. Distinguishing Features: Stable Dune Barrens are distinguished from Maritime Dry Grassland and Dune Grass by the scarcity of the grasses characteristic of those types. They are distinguished from Live Dune Barrens by a stable substrate and well-established, if sparse, vegetation. They are distinguished from all other barrier island communities by low plant cover and abundant dry, bare sand. These communities often occur in fine-scale mosaics with Maritime Dry Grassland, Maritime Wet Grassland, Maritime Shrub, Maritime Vine Tangle, and young Maritime Evergreen Forest in the heterogeneous environment created by irregular interior dunes. They may contain small inclusions of less barren woody or herbaceous vegetation. The Beach Heather Subtype is distinguished by the presence of Hudsonia tomentosa, Lechea maritima, or other species confined to more northern locations. Synonyms: Hudsonia tomentosa / Panicum amarum var. amarulum Dwarf-shrubland (CEGL003950). Ecological Systems: Northern Atlantic Coastal Plain Dune and Swale (CES203.264).

  • Biogeographic Analysis of the Woody Plants of the Southern Appalachians
    AMERICAN JOURNAL OF BOTANY RESEARCH ARTICLE B IOGEOGRAPHIC ANALYSIS OF THE WOODY PLANTS OF THE SOUTHERN APPALACHIANS: IMPLICATIONS FOR THE ORIGINS OF 1 A REGIONAL FLORA P AUL S. MANOS 2 AND J OSÉ E DUARDO M EIRELES Department of Biology, Box 90338 Duke University, Durham, North Carolina 27708-0338 USA • Premise of the study: We investigated the origins of 252 Southern Appalachian woody species representing 158 clades to ana- lyze larger patterns of biogeographic connectivity around the northern hemisphere. We tested biogeographic hypotheses re- garding the timing of species disjunctions to eastern Asia and among areas of North America. • Methods: We delimited species into biogeographically informative clades, compiled sister-area data, and generated graphic representations of area connections across clades. We calculated taxon diversity within clades and plotted divergence times. • Key results: Of the total taxon diversity, 45% were distributed among 25 North American endemic clades. Sister taxa within eastern North America and eastern Asia were proportionally equal in frequency, accounting for over 50% of the sister-area connections. At increasing phylogenetic depth, connections to the Old World dominated. Divergence times for 65 clades with intercontinental disjunctions were continuous, whereas 11 intracontinental disjunctions to western North America and nine to eastern Mexico were temporally congruent. • Conclusions: Over one third of the clades have likely undergone speciation within the region of eastern North America. The biogeographic pattern for the region is asymmetric, consisting of mostly mixed-aged, low-diversity clades connecting to the Old World, and a minority of New World clades. Divergence time data suggest that climate change in the Late Miocene to Early Pliocene generated disjunct patterns within North America.

An account of all known species of Plagiostoma including Cryptodiaporthe is presented based on analyses of morphological, cultural, and DNA sequence data. Multigene phylogenetic analyses of DNA sequences from four genes (β-tubulin, ITS, rpb2, and tef1-α) revealed eight previously undescribed phylogenetic species and an association between a clade composed of 11 species of Plagiostoma and the host family Salicaceae. In this paper these eight new species of Plagiostoma are described, four species are redescribed, and four new combinations are proposed. A key to the 25 accepted species of Plagiostoma based on host, shape, and size of perithecia, perithecial arrangement in the host, and microscopic characteristics of the asci and ascospores is provided. Disposition of additional names in Cryptodiaporthe and Plagiostoma is also discussed.
