  • A Unique Raised Bog at Urbana, Ohio.*
    A UNIQUE RAISED BOG AT URBANA, OHIO.* ROBERT B. GORDON, Ohio State University. Located just north of the Champaign County Fair Grounds at Urbana, Ohio, is a unique dome-shaped bog, covered with shrubby vegetation for the most part, in which the center is raised at least ten feet above the margins. An old road crosses the bog. I have been told that it was once the main thorofare from Urbana to Columbus. Horses and wagons passed over it, I suppose, the drivers never realizing that a mat of fibrous roots less than one foot thick was all that held them over a body of water twelve feet in depth. Raised bogs, called "high moors" and "Hochmoore" in foreign literature, have long been known throughout Europe. N. S. Shaler is credited by Nichols with being the first to call attention to these peculiar swamps in North America, in 1888-89. Those which Shaler observed were "mostly limited to the eastern portion of Maine, near the shores of the Bay of Fundy," but some of lesser magnitude were reported for New Hampshire, northern Michigan, and Minnesota. Similar bogs, with centers about 13 feet above their margins, have been reported in the province of New Brunswick by Ganong (1897). Nichols (1919) described bogs of this type encountered in Maine, in which the elevation of the center above the margin varied from 2 or 3 feet to as high as 18 feet (e. g., Denbo Heath, covering several square miles in area). He asserts: "(1) that in the state of Maine raised bogs, in so far as they constitute a distinctive swamp type, are virtually restricted to the proximity of the seacoast; and (2) that in other portions of New England and of the eastern United States this type of bog is practically absent, although in occasional swamps it is possible to detect a slight elevation of the surface above the level of permanent ground water." Warming (1909) has summarized concisely the characteristic features of "Hochmoore." They owe their development to the growth of sphagnum mosses which absorb water that falls in the form of rain or snow.

  • 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. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese

  • Comparative Analysis of the Complete Chloroplast Genome Sequences of Three Closely Related East-Asian Wild Roses (Rosa Sect
    G C A T T A C G G C A T genes Article Comparative Analysis of the Complete Chloroplast Genome Sequences of Three Closely Related East-Asian Wild Roses (Rosa sect. Synstylae; Rosaceae) Ji-Hyeon Jeon and Seung-Chul Kim * Department of Biological Sciences, Sungkyunkwan University, Suwon 16419, Korea; [email protected] * Correspondence: [email protected]; Tel.: +82-31-299-4499 Received: 4 November 2018; Accepted: 27 December 2018; Published: 3 January 2019 Abstract: Species belonging to Rosa section Synstylae (Rosaceae) are mainly distributed in East Asia, and represent recently diverged lineages within the genus. Over decades, inferring phylogenetic relationships within section Synstylae have been exceptional challenges, due to short branch lengths and low support values. Of approximately 36 species in the section Synstylae, Rosa multiflora, Rosa luciae and Rosa maximowicziana are widely distributed in the Sino-Japanese floristic region. In this study, we assembled chloroplast genomes of these three species to compare the genomic features within section Synstylae, and to compare with other infrageneric groups. We found that three Rosa sect. Synstylae species had lost infA genes with pseudogenization, and they were almost identical to each other. Two protein-coding gene regions (ndhF and ycf1) and five non-coding regions (5’matK-trnK, psbI-trnS-trnG, rps16-trnG, rpoB-trnC, and rps4-trnT) were identified as being highly informative markers. Within three section Synstylae chloroplast genomes, 85 simple sequence repeat (SSR) motifs were detected, of which at least 13 motifs were identified to be effective markers. The phylogenetic relationships of R. multiflora, R. luciae and R. maximowicziana could not be resolved, even with chloroplast genome-wide data.

  • CHANGES in the DISTRIBUTION RANGE of POTENTILLA TUCUMANENS/S (ROSACEAE), an ENDANGERED CRYPTIC Speciesi
    ISSN 0373-580 X Bol. Soc. Argent. Bot. 36 (1-2): 151 - 157. 2001 CHANGES IN THE DISTRIBUTION RANGE OF POTENTILLA TUCUMANENS/S (ROSACEAE), AN ENDANGERED CRYPTIC SPECIESi MARTA ARIAS23, JUAN DIAZ RICCI4 and ATILIO CASTAGNARO4 Summary: A correct taxonomic identification is essential for the preservation of biodiversity. In this paper we present simple morphological characters for the identification of the new species recently described, Potentilla tucumanensis. The reproductive period of this species occupies about 10% of the last part of its lifecycle, is considered cryptic because in the vegetative stage it has many morphological similarities with other cohabiting related species; it can be easily confused with them and it is reproductively isolated. Our study also revealed that for the last hundred years P. tucumanensis has suffered a dramatic habitat retraction. Possible causes of this area retraction are discussed. If P tucumanensis had not been recognized asa new species, it would have most likely disappeared without being noticed. Key words: Potentilla tucumanensis, Duchesnea indica, Fragaria vesca, endangered species, cryptic species, anthropogenic changes. Resumen: Cambios en el rango de distribución de Potentilla tucumanensis (Rosaceae), una especie críptica en peligro de extinción. Una correcta identificación taxonómica es esencial para la preservación de la biodiversidad. En este trabajo se presentan caracteres morfológicos sencillos para diferenciar la nueva especip, Potentilla tucumanensis recientemente descripta. Esta especie, cuyo período reproductivo ocupa el 10% final de su ciclo de vida, es considerada críptica debido a que puede ser confundida por su similitud en estado vegetativo, con especies con las cuales cohabita y está aislada reproductivamente. Además, se muestra que en los últimos cien años, P.

Executive Summary This survey was a continuation of several years of rare plant survey on San Juan Public Lands. Funding for the project was provided by San Juan National Forest and the San Juan Resource Area of the Bureau of Land Management. Previous rare plant surveys on San Juan Public Lands by CNHP were conducted in conjunction with county wide surveys of La Plata, Archuleta, San Juan and San Miguel counties, with partial funding from Great Outdoors Colorado (GOCO); and in 2004, public lands only in Dolores and Montezuma counties, funded entirely by the San Juan Public Lands. Funding for 2005 was again provided by San Juan Public Lands. The primary emphases for field work in 2005 were: 1. revisit and update information on rare plant occurrences of agency sensitive species in the Colorado Natural Heritage Program (CNHP) database that were last observed prior to 2000, in order to have the most current information available for informing the revision of the Resource Management Plan for the San Juan Public Lands (BLM and San Juan National Forest); 2.
