IIntroductionntroduction byby FFrancisrancis UnderwoodUnderwood Rhode Island Equisetopsida, Lycopodiopsida and Isoetopsida Special Th anks to the following for giving permission for the use their images. 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. -
Notes on Some Species of Diphasiastrum
Preslia, Praha, 47: 232 - 240, 1975 Notes on some species of Diphasiastrum Poznamky k n~kterym druhum rodu Dipha11iaatrum Josef Holub HOLUB J. (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. -

Lycopodiaceae Clubmoss Family
Lycopodiaceae Page | 46 clubmoss family Upwards of 15 genera comprise this ancient family. Perennial herbs, they somewhat resemble coarse mosses. The solitary sporangia are borne either in a terminal strobilus or are axillary with leaves. Spores are of equal size. In Nova Scotia we have four genera. A. Rhizomes absent; upright stems clustered; axillary sporangia; spores pitted. Huperzia aa. Rhizomes present; upright shoots alternate; sporangia aggregated into B terminal strobili, spores with netlike pattern. B. Strobili on leafy peduncles; mainly of wetland habitats. Lycopodiella bb. Strobili sessile or on peduncles with remote scant leaves; mainly of C dry upland places. C. Tips of stems 5–12mm in diameter; leaves in 6 ranks or Lycopodium more; leaves bristly, free for most of their length, not scalelike. cc. Distal shoots 2–6mm in diameter; leaves in 4–6 ranks, Diphasiastrum strongly overlapping (scalelike) and appressed along the stem with only tips free. Diphasiastrum Holub There are 15–20 species worldwide; numerous hybrids are possible. Generally these clubmosses are northern or subarctic in distribution. Nova Scotia has four species. Rhizomes bear sparse leaves that are reduced to scales, rooting from the lower surfaces. Upright stems are flattened or angled, with 2–5 branches. Leaves are arranged in four ranks and of two sizes. Sporophylls are smaller than unspecialized leaves. 1-7 Lycopodiaceae Key to species A. Plants < 12 cm tall; strobili sessile. Diphasiastrum sitchense Page | 47 aa. Stems 8–50cm; strobili on peduncles. B B. Branches square or angled, bluish. D. tristachyum bb. Branches flat; green. C C. Lateral branches irregular, annual winter bud constrictions D. -
Checklist of the Washington Baltimore Area
Annotated Checklist of the Vascular Plants of the Washington - Baltimore Area Part I Ferns, Fern Allies, Gymnosperms, and Dicotyledons by Stanwyn G. Shetler and Sylvia Stone Orli Department of Botany National Museum of Natural History 2000 Department of Botany, National Museum of Natural History Smithsonian Institution, Washington, DC 20560-0166 ii iii PREFACE The better part of a century has elapsed since A. S. Hitchcock and Paul C. Standley published their succinct manual in 1919 for the identification of the vascular flora in the Washington, DC, area. A comparable new manual has long been needed. As with their work, such a manual should be produced through a collaborative effort of the region’s botanists and other experts. The Annotated Checklist is offered as a first step, in the hope that it will spark and facilitate that effort. In preparing this checklist, Shetler has been responsible for the taxonomy and nomenclature and Orli for the database. We have chosen to distribute the first part in preliminary form, so that it can be used, criticized, and revised while it is current and the second part (Monocotyledons) is still in progress. Additions, corrections, and comments are welcome. We hope that our checklist will stimulate a new wave of fieldwork to check on the current status of the local flora relative to what is reported here. When Part II is finished, the two parts will be combined into a single publication. We also maintain a Web site for the Flora of the Washington-Baltimore Area, and the database can be searched there (http://www.nmnh.si.edu/botany/projects/dcflora). -

Diphasiastrum, a New Genus in Lycopodiaceae
Prestia, Praha, 47: 97 - 110, 1975 Diphasiastrum, a new genus in Lycopodiaceae Diphasiastrum, novy rod celcdi Lycopodiaceae Josef Holub HOLUB J . (1975): Divhasiastrum, a n ew genus in Lycopod~·aceae. - Proslia, Praha., 47: 97 - 110. The Lycopodium cornvlanatum agg. s. l. is a natural and well defin ed group of closely related species in Lycopodiales, characterized by a sp ecial dorsiventral structure of branchlets, a common basic chromosome number (x = 23) and a special type of the natural prothallium (,,Cornplanaturn"-type). The group represents a. distinct evolutio nary branch in t.he Lycopodiaceae s.8. and is therefore accepted h ere as a separate genus - Diphasiastrum HOLUB. A g0nerio description is provided, based mostly on a discussion of characters separating this genuB from oth er natural groups of Lyco podiaceae s.s.; especially the differences from the Lycopodium scariosum agg. = Dipha siurn C. PRESL, with which it has been erroneously united, are considered. Dipha siastrum contains about 30 species (inclusive of interspecies ). New nomenclatura.l combinations for 22 of t hese are proposed and their classification t o area. types is given. Czecho8lovak Academy of Sciences, Botanical I nstitute, 252 43 Pruhonice, Czechoslovakia. INTRODUCTION The club-mosses, placed at the beginning of the classification systems of recent vascular plants, have always attracted the interest of botanists. As far as the taxonomic classification is concerned, much attention was paid, especially by European botanists, in addition to the generic problems, to the difficult Lycopodium complanatum agg. s. I. Still, this group is inadequately known. The present author has been studying the club-mosses extensively for years and a paper on Diphasium has been in preparation since 1964 (see HoLUB 1964 : 128 ). -

Checklist of Montana Vascular Plants
Checklist of Montana Vascular Plants June 1, 2011 By Scott Mincemoyer Montana Natural Heritage Program Helena, MT This checklist of Montana vascular plants is organized by Division, Class and Family. Species are listed alphabetically within this hierarchy. Synonyms, if any, are listed below each species and are slightly indented from the main species list. The list is generally composed of species which have been documented in the state and are vouchered by a specimen collection deposited at a recognized herbaria. Additionally, some species are included on the list based on their presence in the state being reported in published and unpublished botanical literature or through data submitted to MTNHP. The checklist is made possible by the contributions of numerous botanists, natural resource professionals and plant enthusiasts throughout Montana’s history. Recent work by Peter Lesica on a revised Flora of Montana (Lesica 2011) has been invaluable for compiling this checklist as has Lavin and Seibert’s “Grasses of Montana” (2011). Additionally, published volumes of the Flora of North America (FNA 1993+) have also proved very beneficial during this process. The taxonomy and nomenclature used in this checklist relies heavily on these previously mentioned resources, but does not strictly follow anyone of them. The Checklist of Montana Vascular Plants can be viewed or downloaded from the Montana Natural Heritage Program’s website at: http://mtnhp.org/plants/default.asp This publication will be updated periodically with more frequent revisions anticipated initially due to the need for further review of the taxonomy and nomenclature of particular taxonomic groups (e.g. Arabis s.l ., Crataegus , Physaria ) and the need to clarify the presence or absence in the state of some species. -
