  • Common Yellow Woodsorrel
    A Horticulture Information article from the Wisconsin Master Gardener website, posted 23 May 2008 Common Yellow Woodsorrel Common yellow woodsorrel, Oxalis stricta, is a native North American plant (also found in Eurasia) which is usually considered a weed. It has numerous common names, including common yellow oxalis, sour grass, shamrock, sleeping beauty, sour trefoil, and sheep’s clover. It also has many synonyms: Ceratoxalis coloradensis, O. dillenii, O. europaea, O. prostrate, O. rupestris, and Xanthoxalis fl orida. It is found in 46 states, but is most numerous in the eastern U. S. and into Canada. This species differs from other wood sorrels by being more erect, the stems grow at a sharp angle (about 90º) from the main stem and Common yellow woodsorrel. the seed pods bend sharply upward on their stalks. Common yellow woodsorrel is distinct from other wood sorrels in that the seed pods bend sharply upward on their stalks, and the stalks also grow at a sharp angle from the main stalk (both angles are about 90 degrees). It also tends to grow in a more upright fashion than other An infestation of common yellow woodsorrel. wood sorrels (stricta means “upright”). This herbaceous plant may grow either as an annual or as a weak perennial. Although it prefers moist soil, and partial shade, it is tolerant of a wide range of conditions. It is commonly found in fi elds, woods and borders, along roadsides and in other waste areas, and will even grow in the cracks of sidewalks. It is also a common summer annual in lawns.

  • Oxalis Violacea L. Violet Wood-Sorrel
    New England Plant Conservation Program Oxalis violacea L. Violet Wood-Sorrel Conservation and Research Plan for New England Prepared by: Thomas Mione Professor Central Connecticut State University For: New England Wild Flower Society 180 Hemenway Road Framingham, MA 01701 508/877-7630 e-mail: [email protected] • website: www.newfs.org Approved, Regional Advisory Council, December 2002 1 SUMMARY Violet Wood-Sorrel (Oxalis violacea L., Oxalidaceae) is a low-growing herbaceous, self-incompatible perennial that produces violet flowers in May, June and again in September. Reproduction is both sexual (with pollination mostly by bees), and asexual (by way of runners). The species is widely distributed in the United States but is rare in New England. Oxalis violacea is an obligate outcrosser: the species is distylous, meaning that there are two flower morphs (pin and thrum), with a given plant producing one morph, not both. Pin flowers are more common than thrum flowers. In New England, the habitat varies from dry to moist, and for populations to remain vigorous forest canopies must remain partially open. Succession, the growth of plants leading to shading, is a factor contributing to decline of O. violacea in New England, as are invasive species and habitat fragmentation. Fire benefits this species, in part by removing competitors. Human consumption of the leaves has been reported. Oxalis violacea has a Global Status Rank of G5, indicating that it is demonstrably widespread, abundant and secure. In Massachusetts, it is ranked as Threatened; five occurrences are current (in four towns among three counties) and 10 are historic. In Connecticut, it is listed as a species of Special Concern; 10 occurrences are current (in ten towns among six counties) and 19 are historic.

(WSSI) has conducted a habitat evaluation and search for the rough avens (Geum laciniatum) in Lake Accotink Park in Fairfax County, Virginia. This habitat evaluation and search was undertaken at the request of Fairfax County, because the rough avens had been recorded in the vicinity of Lake Accotink in the past. This report discusses the distribution and habitat associations of the rough avens, details the methodology of our habitat evaluation and search, and presents our findings and conclusions. Although habitat for this species is present within the study area, no rough avens were found during this search. General Distribution and Habitat Associations of the Rough Avens The rough avens is considered a rare species and is typically found in wet areas such as fens and meadows in the northern Piedmont and mountains of Virginia. It is usually found growing in calcareous or mafic soils, which are found in these regions of Virginia. In Virginia, it is known from six counties, including Augusta, Bath, Bland, Fairfax, Fauquier, and Tazewell (Harvill, et al, 1992; Virginia Botanical Associates, 2015). The rough avens has been recorded in 27 eastern and Midwestern states, and in Ontario, Quebec, New Brunswick, and Nova Scotia, Canada.

  • Leafy Spurge in Saskatchewan1
    Reprinted with permission from: Ecological Monographs. Winter 1962. 32:1-29. Published by: University of Saskatchewan. Leafy spurge in Saskatchewan1 G. W. SELLECK, R. T. COUPLAND, and C. FRANKTON Selleck, Monsanto Chemical Company, St. Louis, Missouri. Coupland and Frankton, Plant Research Institute, Canada Department of Agriculture, Ottawa. Introduction The present interest in the study of leafy spurge (Euphorbia esula L.) has been prompted by the steady advance of this weed since its discovery in North America in 1827. The weed was not recognized in western Canada until the early part of the 20th century. Although the rate of spread has not been rapid, the methods of control used have been relatively ineffective, with the result that large areas of land have become infested. This has convinced many agriculturalists that, if unchecked, it will become a major prob- lem in western Canadian agriculture. Difficulty in control has been enhanced by lack of knowledge concerning relation to habitat and the developmental life history of leafy spurge under western Canadian conditions. The need for detailed studies of this persistent weed was realized from the findings of the Sas- katchewan Weed Survey, which was conducted during 1949-1955 concurrently with the early phases of the studies reported here. More than 9,800 acres were found to be infested in 1/3 of the settled portion of the province covered by the sur- vey. The threat from this and other persistent perennial weeds in Sas- katchewan has influenced the provincial government to provide financial assistance to rural mu- nicipalities which use approved Fig. 1. Leafy spurge growing in competition with methods in their control programs.

  • Kimberly Norton Taylor1 and Dwayne Estes
    The floristic and community ecology of seasonally wet limestone glade seeps of Tennessee and Kentucky Kimberly Norton Taylor1 and Dwayne Estes Austin Peay State University Department of Biology and Center of Excellence for Field Biology Clarksville, Tennessee 37044, U.S.A. [email protected], [email protected] ABSTRACT An open, seasonally wet seep community supporting herbaceous vegetation occurs within the limestone cedar glade complex of the southeastern United States. The purpose of this study is to describe the floristic composition of these limestone glade seeps. A floristic inventory of 9 season- ally wet sites in central Tennessee and south-central Kentucky was performed, documenting 114 species and infraspecific taxa in 91 genera and 43 families. Vegetation analysis identified the dominant taxa as Eleocharis bifida (% IV 20.3), Sporobolus vaginiflorus (% IV 11.94), Hypericum sphaerocarpum (% IV 5.97), Allium aff. stellatum (% IV 4.71), Clinopodium glabellum/arkansanum (% IV 4.15), Schoenolirion croceum (% IV 3.89), Juncus filipendulus (% IV 3.89), and Carex crawei (% IV 3.84). Gratiola quartermaniae and Isoëtes butleri are also important members of the community and may serve as indicator species. A wetland assessment of the seep community was performed according to the U.S. Army Corps of Engineers Wetland Delineation Manual and appropriate regional supplements. Wetland vegetation requirements are satisfied in 8 of the 9 seasonally wet sites sampled. The limestone glade seeps appear to represent a previously unclassified seasonal wetland type. RESUMEN Una comunidad abierta, húmeda estacionalmente por filtración, compuesta por vegetación herbácea se da en el complejo de pantanos cal- cáreos de cedro del sureste de los Estados Unidos.
