  • Lycopodium (Spp) L. Ground Pine
    Kasey Hartz Natural Area Reference Sheet Lycopodium (spp) L. Ground pine. Lycopodiaceae (Club-moss Family) Blooming season: Not a flowering plant. Spores produced in July-September. Plant: Tree like in form, 10-25 cm tall. Horizontal stem, not a true rhizome; grows at one end only, and the opposite end dies, resulting in the plant slowly moving forward year by year (Billington 1952). Leaves: Evergreen, scale like. Flower: None, spores are produced on strobilus cones. Fruit: None, but what is formed are strobilus cones which are sessile, having no stalks. Usually 1-3 cones, 1.5-5.5 cm long, maturing July-September. Spores are sulphur yellow with a high oil content. Can be confused with: Many species of Lycopodium can be confused and hybrids may also be found. Geographic range: Type specimen location: State: Throughout. Regional: Newfoundland - Alaska, south to North Carolina and Indiana. Habitat: Local: Riparian. Regional: Moist woods. Common local companions: Pine, ferns, maples, and beech Kasey Hartz Natural Area Reference Sheet Lycopodium obscurum L. 2 Ground Pine Usages: Human: Because of the spores have a high oil content and are quite flammable, they were used as flash powder for the first photographic cameras(Harris 2003); for fireworks (Billington 1952); and to imitate lightning flashes for theatrical performances (Millspaugh 1892, 1974). Their oil content led to them being used by pharmacists in boxes of pills to prevent them sticking together (possibly a different species of Lycopodium). Medicinal uses in the past included treatments for gout, menstrual disorders, nervous disorders, fevers, and as a styptic and an emetic.

Robbin Moran New York Botanical Garden George Yatskievych and Ann Larson Missouri Botanical Garden Jan De Laet, plantsystematics.org Th is pdf is a companion publication to Rhode Island Equisetopsida, Lycopodiopsida & Isoetopsida at among-ri-wildfl owers.org Th e Elfi n Press 2016 Introduction Formerly known as fern allies, Horsetails, Club-mosses, Fir-mosses, Spike-mosses and Quillworts are plants that have an alternate generation life-cycle similar to ferns, having both sporophyte and gametophyte stages. Equisetopsida Horsetails date from the Devonian period (416 to 359 million years ago) in earth’s history where they were trees up to 110 feet in height and helped to form the coal deposits of the Carboniferous period. Only one genus has survived to modern times (Equisetum). Horsetails Horsetails (Equisetum) have jointed stems with whorls of thin narrow leaves. In the sporophyte stage, they have a sterile and fertile form. Th ey produce only one type of spore. While the gametophytes produced from the spores appear to be plentiful, the successful reproduction of the sporophyte form is low with most Horsetails reproducing vegetatively. Lycopodiopsida Lycopodiopsida includes the clubmosses (Dendrolycopodium, Diphasiastrum, Lycopodiella, Lycopodium , Spinulum) and Fir-mosses (Huperzia) Clubmosses Clubmosses are evergreen plants that produce only microspores that develop into a gametophyte capable of producing both sperm and egg cells. Club-mosses can produce the spores either in leaf axils or at the top of their stems. Th e spore capsules form in a cone-like structures (strobili) at the top of the plants.

  • Cyrtomium Falcatum, New to Tbe Italian Flora
    Flora Mediterranea 3 - 1993 261 F. Bonafede, C. Ferrari & A. Vigarani Cyrtomium falcatum, new to tbe Italian flora Abstract Bonafede, F., Ferrari, C. & Vigarani, A. 1993: Cyrtomium falcatum, new to the Italian flora - Fl. Medil. 3: 261-264. 1993. - ISSN 1120-4052. The occurrence of a Cyrtomium falcatum population naturalized in the southem Po Valley (Emilia-Romagna region, Italy), is reported. This is the first record of the species for Italy, since all previous Italian findings of Cyrtomium belong to C. fortunei . The genus Cyrtomium C. PresI (Aspidiaceae) comprises about 20 species distributed mainly in the tropical and subtropical zones of Africa, America and Asia, in damp rocky habitats. Some authors include this genus in Polystichum on the basis of similarities in the morphology of the pinna and of the shield-shaped indusium. Cyrtomium falcatum (L. fil.) C. PresI is native to E. Asia and is cultivated as an omamental plant in Europe. Jalas & Suominen (1972), under the synonym Polystichum falcatum (L. fil.) Diels, report its being naturalized in Portugal and Great Britain, without giving further details of its European distribution. Badré & Deschatres (1979) include it among the French fem species as an alien naturalized near Nice. Specimens of Cyrtomium found in S. Switzerland near Brissago (Kramer in E. Pignatti & al) and in N. Italy (near Cannobio, in Lombardy, and on Mount Ragogna, in the Friuli Pre-Alps) alI to C. fortunei J. Sm. (S. Pignatti 1982; E. Pignatti & al. 1983), although the last-named one had at first been referred to as "e. falcatum" (Poldini 1980).

(1975): Notes on some species of Diphasiastrum. - Preslia, Praha, 47: 232- 240. Taxonomic and nomenclatural problems of some species of Diphasiastrum HOLUB are discussed. A special attention is pa.id to the interspecies D. / X / issleri and D. / x / zei­ leri. Original plants of D. / x / issleri correspond to the combination D. alpinum - D. complanatum. Plants corresponding to the combination D. alpinum - D. tristachyum have been collected in the ~umava Mts. Some taxa described from the subarctic regions of Europe and North America are shown to belong most probably to the neglected interspecies D. / x / zeileri. Botanical I nstitute, Czechoslovak Academy of Sciences, 25~ 43 Prithonice, Czecho.,lovakia. INTRODUCTION This is a second part of my study of the new genus Diphasiastrum (HOLUB 1975), which could not be published in this journal in its entirety. Notes on taxonomy and nomenclature are selected from materials gathered originally for my "Catalogue of Czechoslovak vascular plants". With regard to the character of that work the present observations summarize the results of my own studies and suggests problems to be studied in the future. OBSERVATIONS f!.iphasiastrum alpinum (L.) HOLUB Two varieties have been described in this species (both under the name Lycopodium alpi­ nttm L.): var. thellungii HERTER from Switzerland and var. planiramulosum TAKEDA from Japan. Both these taxa, especially the first one, require a taxonomic revision; the possibility cannot be exclu<led that they are conspecific with D. / x / issleri.

During the last decade, evidence has been accumulating about the polyphyletism within Blechnum Linnaeus (1753: 1077) (e.g. Shepherd et al. 2007, Rothfels et al. 2012, Gabriel y Galán et al. 2013, Perrie et al. 2014). Recent molecular studies (Gasper et al. 2016a) lead to an updated classification attempting to put morphological characters into a natural, phylogenetic relation (Gasper et al. 2016b). Because of these changes, the species most people associate with the genus Blechnum, B. spicant (Linnaeus 1753: 1066) Roth (1794: 56), is now treated under Struthiopteris Scopoli (1754: 25). Struthiopteris spicant (L.) F.W.Weiss (1770: 287), a widely distributed plant in the Northern Hemisphere, is characterized by having strongly dimorphic fronds (Lawalrée 1964), but it shows certain morphological variability that has led to the recognition of several forms, which have been taxonomically treated in several ways, the varietal rank being the currently accepted.

  • 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.

  • Ferns, Cycads, Conifers and Vascular Plants
    Flora of Australia Glossary — Ferns, Cycads, Conifers and Vascular plants A main glossary for the Flora of Australia was published in Volume 1 of both printed editions (1981 and 1999). Other volumes contain supplementary glossaries, with specific terms needed for particular families. This electronic glossary is a synthesis of all hard-copy Flora of Australia glossaries and supplementary glossaries published to date. The first Flora of Australia glossary was compiled by Alison McCusker. Mary D. Tindale compiled most of the fern definitions, and the conifer definitions were provided by Ken D. Hill. Russell L. Barrett combined all of these to create the glossary presented here, incorporating additional terms from the printed version of Volume 37. This electronic glossary contains terms used in all volumes, but with particular reference to the flowering plants (Volumes 2–50). This glossary will be updated as future volumes are published. It is the standard to be used by authors compiling future taxon treatments for the Flora of Australia. It also comprises the terms used in Species Plantarum — Flora of the World. Alternative terms For some preferred terms (in bold), alternative terms are also highlighted (in parentheses). For example, apiculum is the preferred term, and (=apiculus) is an alternative. Preferred terms are those also used in Species Plantarum — Flora of the World. © Copyright Commonwealth of Australia, 2017.

  • Ecophysiology of Four Co-Occurring Lycophyte Species: an Investigation of Functional Convergence
    Research Article Ecophysiology of four co-occurring lycophyte species: an investigation of functional convergence Jacqlynn Zier, Bryce Belanger, Genevieve Trahan and James E. Watkins* Department of Biology, Colgate University, Hamilton, NY 13346, USA Received: 22 June 2015; Accepted: 7 November 2015; Published: 24 November 2015 Associate Editor: Tim J. Brodribb Citation: Zier J, Belanger B, Trahan G, Watkins JE. 2015. Ecophysiology of four co-occurring lycophyte species: an investigation of functional convergence. AoB PLANTS 7: plv137; doi:10.1093/aobpla/plv137 Abstract. Lycophytes are the most early divergent extant lineage of vascular land plants. The group has a broad global distribution ranging from tundra to tropical forests and can make up an important component of temperate northeast US forests. We know very little about the in situ ecophysiology of this group and apparently no study has eval- uated if lycophytes conform to functional patterns expected by the leaf economics spectrum hypothesis. To determine factors influencing photosynthetic capacity (Amax), we analysed several physiological traits related to photosynthesis to include stomatal, nutrient, vascular traits, and patterns of biomass distribution in four coexisting temperate lycophyte species: Lycopodium clavatum, Spinulum annotinum, Diphasiastrum digitatum and Dendrolycopodium dendroi- deum. We found no difference in maximum photosynthetic rates across species, yet wide variation in other traits. We also found that Amax was not related to leaf nitrogen concentration and is more tied to stomatal conductance, suggestive of a fundamentally different sets of constraints on photosynthesis in these lycophyte taxa compared with ferns and seed plants. These findings complement the hydropassive model of stomatal control in lycophytes and may reflect canaliza- tion of function in this group.
