  • How to Identify New Brunswick Violets
    How to Identify New Brunswick Violets Sponsored by the New Brunswick Botany Club Introduction : Violets are always exciting to find while walking in the field in early summer. They are so easy to identify as to their genus. However, most people will stop there, because they are not easy to identify at the species level - many minute characteristics must be examined...and they easily form difficult to describe hybrids. Approached in the right mix of adventurousness and humility, sorting out violets can be fun. However, should efforts end in exasperation, just keep in mind that the violets never read the botany books. (Choukas-Bradley 2004). In order to correctly identify violets the following features must be examined : these are stems, leaves and flowers. Above-ground stems are : a) acaulescent (stemless) b) caulescent (stemmed) In acaulescent species the rhizomes or stolons gives rise to a crown of basal leaves and flowers. Care should be taken to assess the position of leaves since some species (i.e. Viola adunca and Viola labradorica - caulescent species) may have very short (less than 1 cm) stems at flowering and may appear acaulescent. Below-ground stems are : a) slender rhizome b) stout rhizome c) taproot Rhizomes are slender (mostly 1 to 3 mm thick) and travel horizontally underground, or stout (mostly 4 to 6 mm thick) and are usually oriented vertically underground - these are the perennials. Annuals have a vertical, fibrous root known as a taproot. To evaluate a slender versus a stout rhizome in the field, just place your thumb and index vertically around the base of a plant, near the soil.

  • Jacob's-Ladder
    Jacob’s-ladder (Polemonium vanbruntiae) Phlox Family (Polemoniaceae) Pennsylvania Endangered Plant Species State Rank: S1 (critically imperiled) Global Rank: G3 (vulnerable) SIGNIFICANCE The Jacob’s-ladder has been given a status of Endangered on the Plants of Special Concern in Pennsylvania list by the Pennsylvania Biological Survey and the Department of Conservation and Natural Resources, based on the relatively few populations that have been documented in the state. It is considered a globally rare species by the Natural Heritage Program. DESCRIPTION The Jacob’s-ladder is a perennial herb to three feet in height. The leaves are alternately arranged and divided into numerous leaflets with entire margins. The individual flowers, appearing in late June and early July, have blue petals and protruding stamens and style. The fruit is a many-seeded capsule. A more common and widespread species, Polemonium reptans, is similar but is smaller in size, has the stamens and style not protruding from the flower, has more of a woodland habitat, and blooms in spring. North American State/Province Conservation Status Map by NatureServe (August 2007) State/Province Status Ranks SX – presumed extirpated SH – possibly extirpated S1 – critically imperiled S2 – imperiled S3 – vulnerable S4 – apparently secure S5 – secure Not ranked/under review HABITAT The species grows in wet soil in woods, thickets and openings. RANGE The Jacob’s-ladder is found in northeastern North America from southern Canada to West Virginia. It is known historically from several widely scattered occurrences in Pennsylvania, although all of the currently known populations are in the northeastern part of the state. REFERENCES .

Email: [email protected] Abstract. Since 1991, researchers from approximately 45 nations have participated in eight International Conferences on Serpentine Ecology (ICSE). The Conferences are coordinated by the International Serpentine Ecology Society (ISES), a formal research society whose members study geological, pedological, biological and applied aspects of ultramafic (serpentine) ecosystems worldwide. These conferences have provided an international forum to discuss and synthesise multidisciplinary research, and have provided opportunities for scientists in distinct fields and from different regions of the world to conduct collaborative and interdisciplinary research. The 8th ICSE was hosted by Sabah Parks in Malaysia, on the island of Borneo, and attracted the largest delegation to date, 174 participants from 31 countries. This was the first time an ICSE was held in Asia, a region that hosts some of the world’s most biodiverse ultramafic ecosystems.

  • Ferns of the National Forests in Alaska
    Ferns of the National Forests in Alaska United States Forest Service R10-RG-182 Department of Alaska Region June 2010 Agriculture Ferns abound in Alaska’s two national forests, the Chugach and the Tongass, which are situated on the southcentral and southeastern coast respectively. These forests contain myriad habitats where ferns thrive. Most showy are the ferns occupying the forest floor of temperate rainforest habitats. However, ferns grow in nearly all non-forested habitats such as beach meadows, wet meadows, alpine meadows, high alpine, and talus slopes. The cool, wet climate highly influenced by the Pacific Ocean creates ideal growing conditions for ferns. In the past, ferns had been loosely grouped with other spore-bearing vascular plants, often called “fern allies.” Recent genetic studies reveal surprises about the relationships among ferns and fern allies. First, ferns appear to be closely related to horsetails; in fact these plants are now grouped as ferns. Second, plants commonly called fern allies (club-mosses, spike-mosses and quillworts) are not at all related to the ferns. General relationships among members of the plant kingdom are shown in the diagram below. Ferns & Horsetails Flowering Plants Conifers Club-mosses, Spike-mosses & Quillworts Mosses & Liverworts Thirty of the fifty-four ferns and horsetails known to grow in Alaska’s national forests are described and pictured in this brochure.

HARRIS University of Massachusetts, Fernald Hall, 270 Stockbridge Road, Amherst, MA 01003 EARL B. ALEXANDER 1714 Kasba Street, Concord, CA 94518 ABSTRACT. Serpentine outcrops are model habitats for geoecological studies. While much attention has been paid to serpentine outcrops worldwide, the literature on eastern North American serpentine and associated biota is scant. This review examines the available literature, published and unpublished, on geoecological studies conducted on serpentine in eastern North America, from Newfoundland through Que´bec and New England south to Alabama. Most serpentine outcrops in the region have been mapped, but there have been few intensive mineralogical and pedological investigations. The limited soil analyses available suggest elevated levels of heavy metals such as Ni, near-neutralpH values, and Ca:Mg ratios , 1, characteristic of serpentine soils worldwide. Botanical studies to date have largely focused on floristic surveys and the influence of fire exclusion and grazing on indigenous vegetation. To date, 751 taxa of vascular plants belonging to 92 families have been reported from serpentine outcrops in the region. Two taxa, Agalinis acuta and Schwalbea americana, are federally endangered in the United States while many others are listed as rare, endangered, or imperiled in one or more states or provinces.

  • Adiantum Viridimontanum, Aspidotis Densa, Minuartia Marcescens, and Symphyotrichum Rhiannon: Additional Serpentine Endemics from Eastern North America
    Soil and Biota of Serpentine: A World View 2009 Northeastern Naturalist 16(Special Issue 5):111–120 Adiantum viridimontanum, Aspidotis densa, Minuartia marcescens, and Symphyotrichum rhiannon: Additional Serpentine Endemics from Eastern North America Tanner Harris1 and Nishanta Rajakaruna2,3,* Abstract - Serpentine outcrops around the world are known to harbor disproportion- ately high rates of plant endemism. Remarkable cases of serpentine endemism occur in New Caledonia and Cuba, with 3178 and 920 endemic taxa, respectively, found solely on serpentine. Despite the patchy occurrence of serpentine in eastern North America from Québec and Newfoundland south to Alabama, only one taxon, Cerastium veluti- num var. villosissimum, has been broadly recognized as a serpentine endemic for the region. Based on reports in the literature, we suggest that Adiantum viridimontanum, Minuartia marcescens, and Symphyotrichum rhiannon be considered endemic to serpentine soils from the east coast of North America. Aspidotis densa, with several disjunct populations on and off serpentine in western North America, is known solely from serpentine soils where it occurs in eastern North America and should be consid- ered endemic to the substrate there. The geobotany of eastern North America in general is poorly understood, and additional taxonomic studies on the region’s unique geologic substrates will likely yield further edaphic endemics. Introduction Narrow endemism can result from any number of biological and en- vironmental interactions. However, within a regional climate, geological discontinuities, both topographic and geochemical, are the most common and striking infl uences of narrow endemism (Kruckeberg 1986, Kruck- eberg and Rabinowitz 1985). Among the endemic species resulting from geological discontinuities are edaphic endemics, those species restricted to chemically and/or physically unique soils (Rajakaruna and Boyd 2008).
