Printed on Recycled Paper OREGON FLORA NEWSLETTER 7[21 2001 8 Giant hogweed found in Oregon! By Chnrlene Simpson A few months ago Oregon Department of Agriculture Noxious Weed Control staff members Glem Miller and Tom Forney identified a 20 by 30 foot patch of the noxious weed, giant hogweed (Heracleum mntegazziannm Somm. & Lev.) growing behind a grocery store in Oahdge. The ODA subsequently publicized the find and asked people to report populabons. They received over 140 responses and in alllearned of about 45 mfestations in Clackamas, Columbia, Lane, Marion, Multnomah, and Washmgton counties of western Oregon. The majority of sightings were from the Portland metropolitan area. Giant hogweed resembles its congener, Heracleum lanatum, cow parsnip, but is easily differentiated by its herculean proportions. Hollow stout stems, 2 to 4 inches in diameter, displaying dark redd~sh-purplespots and pustulate bristles support a compound umbel up to 2.5 feet in diameter heanng numerous white flowers. Giant hogweed blooms from mid-June lo mid-July on a stem reaching a height of 10 to 15 feet. Purplish leaf stocks support deeply inc~sedcompound leaves 3 to 5 feet wide. Tlns monster member of the carrot family (Apiaceae) is aparticularly nasty pest. Like other members of its genus, ~tssap contains a glucoside that causes phyto-photo- dermatitis. Sldn contact with the sap, followed by exposure to the sun, produces painful, blisters m susceptible people. The plant is classified as a class A noxious weed in Oregon and Washmgton.

  • 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.

Description: An annual herb from a taproot. Stems ascending to erect, 10-60 cm tall, usually branched from the base and peeling below. Plants are greyish with spreading hairs. Leaves are opposite only near the base, linear or narrowly lanceolate, reduced above, entire or remotely fine-toothed, hairy but nearly glabrous near the base and nearly stalkless. Flowering inflorescence is loose to somewhat crowed in a leafy, terminal spike, glandular, flower-leaves similar to others but entire and smaller. Flowers are fertilized in the bud and do no open.

Lammers ABSTRACT. Onagraceae are a family of 17 genera in seven tribes, with the majority of species in tribes Onagreae and Epilobieae. Despite the species-richness of these two tribes, to date no phylogenetic study has been done with suf!cient taxon sampling to examine relationships between and within these tribes. In this study, we used DNA sequence data from one nuclear region (ITS) and two chloroplast regions (trnL-trnF and rps16) to infer phylogenetic relationships among 93 taxa across the family, with concentrated sampling in the large tribe Onagreae.

    Updates Required to Plant Systematics: A Phylogenetic Approach, Third Edition, as a Result of Recent Publications (Updated June 13, 2014) As necessitated by recent publications, updates to the Third Edition of our textbook will be provided in this document. It is hoped that this list will facilitate the efficient incorporation new systematic information into systematic courses in which our textbook is used. Plant systematics is a dynamic field, and new information on phylogenetic relationships is constantly being published. Thus, it is not surprising that even introductory texts require constant modification in order to stay current. The updates are organized by chapter and page number. Some require only minor changes, as indicated below, while others will require more extensive modifications of the wording in the text or figures, and in such cases we have presented here only a summary of the major points. The eventual fourth edition will, of course, contain many organizational changes not treated below. Page iv: Meriania hernandii Meriania hernandoi Chapter 1.

  • Onagraceae) in North America, Based on Parsimony Analysis of Endemicity and Track Compatibility Analysis1
    GEOGRAPHICAL Liliana Katinas,2 Jorge V. Crisci,2 Warren 3 4 DIVERSIFICATION OF L. Wagner, and Peter C. Hoch TRIBES EPILOBIEAE, GONGYLOCARPEAE, AND ONAGREAE (ONAGRACEAE) IN NORTH AMERICA, BASED ON PARSIMONY ANALYSIS OF ENDEMICITY AND TRACK COMPATIBILITY ANALYSIS1 ABSTRACT Tribes Epilobieae, Gongylocarpeae, and Onagreae, a monophyletic branch in the family Onagraceae, comprise genera endemic to or having their major basal radiation in the Madrean Floristic Region of southwestern North America. Parsimony analysis of endemicity (PAE) and panbiogeography (track compatibility analysis) were performed in order to seek an historical explanation for the patterns of high diversity and endemicity for the group in this region. Twenty- one areas of endemism are delimited, based on previous biogeographic schemes and presence of endemic plant and animal taxa. Based on distributional data on 173 species, a strict consensus PAE cladogram shows four main groups of areas: northern North America, the central Mexican areas, western North America, and eastern North America. Track compatibility analysis resulted in two strongly supported generalized tracks: one includes eastern North America, and the other western North America. PAE and panbiogeographical analyses of the distributional patterns of these taxa suggest a close relationship of eastern and western North America, with both areas more related to the Neotropics than to the Palearctic, and a rather weak association between northern North America and Asia. The discovery of two tracks in eastern and western North America for Epilobieae, Gongylocarpeae, and Onagreae reveal little relationship of North America with Asia or other continents. These tribes display a distinct but contemporaneous biogeographical history that differs from those of the Holarctic.

Introduced species have increased from five percent of the flora to 13% over the last century. Relatively small changes have occurred in plant species duration, species habit or major groups over 100 years. Mean coefficients of conservatism varied from 4.3 to 6.2 in eight areas across the county, with the lowest values in riparian areas and highest values in pine-dominated buttes. Keywords floristics, grassland, Northern Great Plains, South Dakota, vegetation INTRODUCTION This report documents vascular plant species from Harding County, South Dakota, from historical and recent plant collections. Literature describing the flora of Harding County is lacking. The most notable publication is by Visher (1914) who completed a species list for the county. Visher’s publication was based upon collections made by him in 1910-1912, and collections made by Rowley in 1909, Fromme in 1910, and Over in 1911. Heidel and Dueholm (1995) reported on “sensitive” species in Custer National Forest in Carter County, Montana, and Harding County.
