  • 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.

The Natural Resource Technical Report Series is used to disseminate results of scientific studies in the physical, biological, and social sciences for both the advancement of science and the achievement of the National Park Service mission. The series provides contributors with a forum for displaying comprehensive data that are often deleted from journals because of page limitations. All manuscripts in the series receive the appropriate level of peer review to ensure that the information is scientifically credible, technically accurate, appropriately written for the intended audience, and designed and published in a professional manner.

Department nf Botany The University of British Columbia 2075 Wesbrook Place Vancouver, Canada V6T 1W5 26 March 1980 ABSTRACT Seven species are recognized in Arnica subgenus Austromontana and two species in a new subgenus Calarnica based on a critical review and conserva• tive revision of the species. Chromosome numbers are given for 91 populations representing all species, including the first reports for Arnica nevadensis. Results of apomixis, vegetative reproduction, breeding studies, and artifi• cial hybridizations are given. Interrelationships of insect pollinators, leaf miners, achene feeders, and floret feeders are presented. Arnica cordifolia, the ancestral species consists largely of tetraploid populations, which are either autonomous or pseudogamous apomicts, and to a lesser degree diploid, triploid, pentaploid, and hexaploid populations.

Location of work: Santa Rosa Plain, Sonoma County, California 2. Background: Burke’s goldfield (Lasthenia burkei), a small, slender annual herb in the sunflower family (Asteraceae), is known only from southern portions of Lake and Mendocino counties and from northeastern Sonoma County. Historically, 39 populations were known from the Santa Rosa Plain, two sites in Lake County, and one site in Mendocino County. The occurrence in Mendocino County is most likely extirpated. From north to south on the Santa Rosa Plain, the species ranges from north of the community of Windsor to east of the city of Sebastopol. The long-term viability of many populations of Burke’s goldfields is particularly problematic due to population decline. There are currently 20 known extant populations, a subset of which were inoculated into pools at constructed sites to mitigate the loss of natural populations in the context of development.

    Schilling, E.E. and A. Floden. 2014. Barcoding the Asteraceae of Tennessee, tribe Senecioneae. Phytoneuron 2014-34: 1–5. Published 14 March 2014. ISSN 2153 733X BARCODING THE ASTERACEAE OF TENNESSEE, TRIBE SENECIONEAE EDWARD E. SCHILLING AND AARON FLODEN Herbarium TENN Department of Ecology & Evolutionary Biology University of Tennessee Knoxville, Tennessee 37996 [email protected]; [email protected] ABSTRACT Results from barcoding studies of tribe Senecioneae for the Tennessee flora using data from the nuclear ribosomal ITS marker region are presented and include first complete reports of this marker for 3 of the 15 species of these tribes that occur in the state. Sequence data from the ITS region separated all Tennessee species of Arnoglossum , Erechtites , Hasteola , and Rugelia (all of which are native) from one another and from other, non-Tennessee congeners. In contrast, many of the species of Packera , both from the state and from other parts of the southeastern USA, had basically identical ITS sequences. The contrast in the distinctiveness of Arnoglossum species compared to those of Packera suggests the two genera have had different histories of introduction and diversification in southeastern North America. Tribe Senecioneae is one of the largest in Asteraceae and with a worldwide distribution has had the opportunity to diversify in many different regions. The boundaries and circumscription of the tribe have, however, changed over the past few decades, and its generic level circumscription is still being settled (Nordenstam et al. 2009; Pelser et al. 2007, 2010). Notable is the problem of the circumscription of the huge Senecio (ca. 1000 species), but changes have also affected other genera from the southeastern USA, most notably the recognition of Arnoglossum and Hasteola as distinct from Cacalia (Anderson 1974).
