  • Liverworts of the Wellington Area J
    Liverworts of the Wellington Area J. E. Braggins1 LIVERWORT FEATURES Liverworts are plants similar in many ways to mosses: they are usually small, and generally lack the hard supporting tissues of larger plants such as ferns. Like ferns, liverworts show alternation of generations, having separate gametophyte and sporophyte entities; unlike ferns the sporophyte is not a separate plant. As with mosses, the gametophyte generation is the dominant phase of the life cy- cle, and the sporophyte generation is permanently dependent on it. Liverworts show a greater range in general morphology and form than mosses, and as well as normal leafy plants, there are dozens of species of thalloid liverworts that lack organisation into stems and leaves. The most striking differences between mosses and liverworts are in the sporophytes where liverworts have a simple outer wall lacking the peristome of mosses, and in the capsule which usually splits into four valves to release the spores. Mixed amongst the spores are hair- like elaters, which flick and twist as they dry out, helping to throw the spores clear. The stalk that bears the capsule (the seta) remains short until the capsule is mature, then, by cell elongation, it expands rapidly to its full size. Thus, the expanded seta of a liverwort is a delicate translucent structure, not tough and wiry like a moss seta which elongates slowly by cell growth. The vegetative parts of leafy liverworts differ from mosses in details of cell shape, contents, leaf structure (liverwort leaves lack a central nerve or vein), shape (liverwort leaves are rarely markedly elongate but are often complexly lobed) and position.

  • Checklist of the Liverworts and Hornworts of the Interior Highlands of North America in Arkansas, Illinois, Missouri and Oklahoma
    Checklist of the Liverworts and Hornworts of the Interior Highlands of North America In Arkansas, Illinois, Missouri and Oklahoma Stephen L. Timme T. M. Sperry Herbarium ‐ Biology Pittsburg State University Pittsburg, Kansas 66762 and 3 Bowness Lane Bella Vista, AR 72714 [email protected] Paul Redfearn, Jr. 5238 Downey Ave. Independence, MO 64055 Introduction Since the last publication of a checklist of liverworts and hornworts of the Interior Highlands (1997)), many new county and state records have been reported. To make the checklist useful, it was necessary to update it since its last posting. The map of the Interior Highlands of North America that appears in Redfearn (1983) does not include the very southeast corner of Kansas. However, the Springfield Plateau encompasses some 88 square kilometers of this corner of the state and includes limestone and some sandstone and shale outcrops. The vegetation is typical Ozarkian flora, dominated by oak and hickory. This checklist includes liverworts and hornworts collected from Cherokee County, Kansas. Most of what is known for the area is the result of collections by R. McGregor published in 1955. The majority of his collections are deposited in the herbarium at the New York Botanical Garden (NY). This checklist only includes the region defined as the Interior Highlands of North America. This includes the Springfield Plateau, Salem Plateau, St. Francois Mountains, Boston Mountains, Arkansas Valley, Ouachita Mountains and Ozark Hills. It encompasses much of southern Missouri south of the Missouri River, southwest Illinois; most of Arkansas except the Mississippi Lowlands and the Coastal Plain, the extreme southeastern corner of Kansas, and eastern Oklahoma (Fig.

  • Identification of Conifer Trees in Iowa This Publication Is Designed to Help Identify the Most Common Trees Found in Iowa
    Identification of Conifer Trees in Iowa This publication is designed to help identify the most common trees found in Iowa. It is based on vegetative characteristics including leaves, fruit, and bark. It is neither complete nor without possible oversights. Separate species are grouped by similar characteristics, mainly based on type and arrangement of leaves. These groups are; awl- or scale- like needles; single needles, flattened with rounded tips; single needles, square in cross section, with pointed tips; and needles in bundles or fasticles of two or more. Remember, vegetative character- istics are quite variable; use more than one specimen for comparison. Awl- or scale-like needles Juniperus Virginiana Eastern Red Cedar Leaves are dark green; leaves are both awl- and scale-like; cone is dark blue and berry-like. Thuja occidentalis Northern White Cedar Leaves are flattened and only of the scale type; cones have 4-6 scales; foliage is light green. Juniperus communis Common Juniper Leaves are awl shaped; cone is dark blue and berry-like. Pm-1383 | May 1996 Single needles, flattened with rounded tips Pseudotsuga menziesii Douglas Fir Needles occur on raised pegs; 3/4-11/4 inches in length; cones have 3-pointed bracts between the cone scales.

NADEZDA A. KONSTANTINOVA1 & ANNA A. VILNET1 1Polar-Alpine Botanical Garden–Institute RAS, 184256, Kirovsk, Russia, email: [email protected], [email protected] Abstract The new species Jungermannia calcicola Konstant. et Vilnet, is described based on a critical reinvestigation of morphologi- cal features and molecular analyses of trnL–trnF and trnG intron cpDNA sequences of forty samples of Jungermannia s. str. The new species is described and illustrated as well as noting its differentiation from allied species and distribution patterns. New data on some taxonomical ambiguities and on the taxa delimitation in the Jungermannia s. str. are discussed. Key words: Jungermannia calcicola sp. nov., liverworts, taxonomy, molecular systematics, distribution Introduction Jungermannia Linnaeus (1753: 1131) is one of the oldest described genera of leafy liverworts. Since its description the treatment of this genus has been drastically changed. At the end of the 20th to the beginning of the 21st centuries most bryologists accepted Jungermannia in the wide sense including Solenostoma Mitten (1865a: 51), Plectocolea (Mitten 1865b: 156) Mitten (1873: 405), Liochlaena Nees in Gottsche et al. (1845: 150). But in recent molecular phylogenetic studies Jungermannia s. lat. has been proved to be a mixture of phylogenetically unrelated taxa, some of which have been elevated to distinct families, e.g., Solenostomataceae Stotler et Crand.-Stotl.

  • Functional Gene Losses Occur with Minimal Size Reduction in the Plastid Genome of the Parasitic Liverwort Aneura Mirabilis
    Functional Gene Losses Occur with Minimal Size Reduction in the Plastid Genome of the Parasitic Liverwort Aneura mirabilis Norman J. Wickett,* Yan Zhang, S. Kellon Hansen,à Jessie M. Roper,à Jennifer V. Kuehl,§ Sheila A. Plock, Paul G. Wolf,k Claude W. dePamphilis, Jeffrey L. Boore,§ and Bernard Goffinetà *Department of Ecology and Evolutionary Biology, University of Connecticut; Department of Biology, Penn State University; àGenome Project Solutions, Hercules, California; §Department of Energy Joint Genome Institute and University of California Lawrence Berkeley National Laboratory, Walnut Creek, California; and kDepartment of Biology, Utah State University Aneura mirabilis is a parasitic liverwort that exploits an existing mycorrhizal association between a basidiomycete and a host tree. This unusual liverwort is the only known parasitic seedless land plant with a completely nonphotosynthetic life history. The complete plastid genome of A. mirabilis was sequenced to examine the effect of its nonphotosynthetic life history on plastid genome content. Using a partial genomic fosmid library approach, the genome was sequenced and shown to be 108,007 bp with a structure typical of green plant plastids. Comparisons were made with the plastid genome of Marchantia polymorpha, the only other liverwort plastid sequence available. All ndh genes are either absent or pseudogenes. Five of 15 psb genes are pseudogenes, as are 2 of 6 psa genes and 2 of 6 pet genes. Pseudogenes of cysA, cysT, ccsA, and ycf3 were also detected. The remaining complement of genes present in M. polymorpha is present in the plastid of A. mirabilis with intact open reading frames. All pseudogenes and gene losses co-occur with losses detected in the plastid of the parasitic angiosperm Epifagus virginiana, though the latter has functional gene losses not found in A.

O. Box 299, St. Louis, MO 63166–0299 U.S.A.; [email protected] Abstract A widely accessible list of known plant species is a fundamental requirement for plant conservation and has vast applications. An index of published names of liverworts and hornworts between 2009 and 2010 is provided as part of a continued effort in working toward producing a world checklist of this group. Included in the list are also names overlooked by earlier indices. The list includes 30 higher taxa, 250 species, 52 infraspecific taxa, 31 autonyms, and two fossils for 2009 and 2010. A number of taxa not covered by the earlier indices for 2000-2008 are also included. Key words: Liverworts, hornworts, index, nomenclature Introduction Under the auspices of the Early Land Plants Today project, there has been a strong community-driven effort attempting to address the critical need to synthesize the vast nomenclatural, taxonomic and global distributional data for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) (von Konrat et al. 2010a). These endeavours are critical in providing the foundation to develop a working checklist of liverworts and hornworts worldwide; the first version is projected to be published in 2012.
