Present-Day Genetic Structure of the Holoparasite Conopholis Americana
Int. J. Plant Sci. 177(2):132–144. 2016. q 2015 by The University of Chicago. All rights reserved. 1058-5893/2016/17702-0003$15.00 DOI: 10.1086/684180 PRESENT-DAY GENETIC STRUCTURE OF THE HOLOPARASITE CONOPHOLIS AMERICANA (OROBANCHACEAE) IN EASTERN NORTH AMERICA AND THE LOCATION OF ITS REFUGIA DURING THE LAST GLACIAL CYCLE Anuar Rodrigues1,* and Saša Stefanović* *Department of Biology, University of Toronto, Mississauga, Ontario L5L 1C6, Canada Editor: Félix Forest Premise of research. Understanding how various organisms respond to previous changes in climate could provide insight into how they may respond or adapt to the current changes. Conopholis americana has a broad distribution across eastern North America, covering both previously glaciated and unglaciated regions. In this study, we investigated the postglacial history and phylogeographic structure of this parasitic plant spe- cies to characterize its genetic variation and structure and to identify the number and locations of refugia. Methodology. Molecular data from 10 microsatellite markers and DNA sequences from the plastid gene/ introns (clpP) were obtained for 281 individuals sampled from 75 populations spanning the current range of the species in eastern North America and analyzed using a variety of phylogeographic methods. Distribution modeling was carried out to determine regions with relatively suitable climate niches for populations at the Last Glacial Maximum (LGM) and present. Pivotal results. We inferred the persistence of a minimum of two glacial refugia for C. americana at the LGM, one in north-central Florida and southern Alabama and another in the Appalachian Mountains near the southern tip of the Blue Ridge Mountains. -

The Vegetative Composition of a Beech-Maple Climax Forest in the Glaciated Plateau of Northeastern Ohio1
174 STANLEY E. PAYNE Vol. 71 THE VEGETATIVE COMPOSITION OF A BEECH-MAPLE CLIMAX FOREST IN THE GLACIATED PLATEAU OF NORTHEASTERN OHIO1 WILLIAM H. SCHLESINGER2 Department of Biological Sciences, University School, Shaker Heights, Ohio ABSTRACT Survey was made of a beech-maple forest by the quarter point method during August, 1968. The forest is located on a mesic, level upland of the glaciated Allegheny Plateau in eastern Cuyahoga County, Ohio, in the Chagrin River drainage basin. Geologically the upland is underlain by Mississippian formations capped by a thin cover of till, in which soils of the Ellsworth soil catena—the Rittman and Wadsworth silt loams—are developed. The dominant plant species in this forest are American beech and sugar maple, which together comprise 68% of the trees recorded and have a total combined importance value of 62%. Red oak, red maple, and cucumbertree are important secondary dominants, but white ash and tuliptree are of little significance in the woodland composition. A greater overall abundance of secondary-associate mixed-mesophytic species than is normally found in such forests occurs. This composition supports the concept of a poly climax beech- maple association and is suggested to be a result of past selective lumbering and a varia- tion in topography and soils. Although there is some evidence of past selective lumbering, the forest appears to be in an essentially undisturbed, virgin state. It has been partially destroyed as the forest is now part of a tract of land developed as a new secondary school campus. INTRODUCTION The survey presented here is part of a complete ecological survey of the proposed campus of the University School in Hunting Valley, Ohio, which was made in August, 1968. -
Wildflowers Near the Wilderness Road Campground
Wildflower Guide for the Wilderness Road Campground and Vicinity Including: Greenleaf Nature Trail Colson Lane Honey Tree Spur Trail Lower portions of Gibson Gap and Lewis Hollow Trails By: John W. Graves March 16, 2007 Wildflowers of Wilderness Road Campground, Green Leaf Nature Trail and Vicinity 3/20/2007 Photos and Text by John W. Graves Rue Anemone (Anemonella thalictroides). The flowers range from pink to white and have from 5 to 10 petal-like sepals. There are no petals. It is com- mon in rich woods throughout the southeast. Rue Anemone was thought to have great healing powers and was adopted by the Persians as a symbol of dis- ease. Although no special powers are attributed to it today, several of the spe- cies have a substance in their sap that has been shown helpful for some foot diseases6. Blooms from March through May. Wood Anemone (Anemone quinquefolia). Legend has that the original home of this flower was Mt. Olympus and that only the winds of spring could open the flower. The name anemone comes from the Greek god of the winds, Anemos. The Chinese refer to this plant as the “death plant” and plant it on the graves of loved ones6. It can be found in rich, moist woods and along the lower portion of the Gibson Gap trail. Beaked Corn Salad (Valerianella radiate). The name comes from European settlers that collected the leaves and plant tops ate them as a salad2. A colony of this plant is found on the lower end of the Honey Tree Spur Trail off the Greenleaf Nature trail. -
Root Parasites of Southern Forests
Summary The five families of root parasites of the South are discussed relative to selection of hosts, ecology, and potential for damage to commercial species. An identification key to all genera of root parasites is included. Plants and flowers of 29 species are illustrated and their distribution in the South mapped. Acknowledgments We wish to thank Dr. W. H. Duncan, Dr. R. Teulings, and Mr C. S. Hanis for contributing pictures. Much credit for the successful growth of parasites in pot culture goes to Mr. C. M. Stangle. Dr. R. E. Eplee, and Dr. I? R. Atsatt reviewed drafts and made helpful suggestions. Finally, Harold Grelen contributed in many ways including substantial improvements in the identification key.

INTRODUCTION This Check List of the Plants of New Jersey Has Been
INTRODUCTION This Check List of the Plants of New Jersey has been compiled by updating and integrating the catalogs prepared by such authors as Nathaniel Lord Britton (1881 and 1889), Witmer Stone (1911), and Norman Taylor (1915) with such other sources as recently-published local lists, field trip reports of the Torrey Botanical Society and the Philadelphia Botanical Club, the New Jersey Natural Heritage Program’s list of threatened and endangered plants, personal observations in the field and the herbarium, and observations by other competent field botanists. The Check List includes 2,758 species, a botanical diversity that is rather unexpected in a small state like New Jersey. Of these, 1,944 are plants that are (or were) native to the state - still a large number, and one that reflects New Jersey's habitat diversity. The balance are plants that have been introduced from other countries or from other parts of North America. The list could be lengthened by hundreds of species by including non-persistent garden escapes and obscure waifs and ballast plants, many of which have not been seen in New Jersey since the nineteenth century, but it would be misleading to do so. The Check List should include all the plants that are truly native to New Jersey, plus all the introduced species that are naturalized here or for which there are relatively recent records, as well as many introduced plants of very limited occurrence. But no claims are made for the absolute perfection of the list. Plant nomenclature is constantly being revised. Single old species may be split into several new species, or multiple old species may be combined into one.
