1 Ophioglossidae (PDF, 873
Ophioglossidae 1 Polypodiopsida Ophioglossidae – Gabelblattgewächse (Polypodiopsida) Zu den Ophioglossidae werden 2 rezente Ordnungen gestellt, die Psilotales (Gabelfarne) und die Ophioglossales (Natternzungenartigen). Die Ophioglossidae sind eine sehr alte Landpflanzengruppe. Die Blätter sind, anders als dies für viele makrophylle Farnpflanzen typisch ist, zu Beginn nicht eingerollt. Ein gemeinsames Merkmal der Psilotales mit den Ophioglossales sind eusporangiate Sporangien, d. h. die Sporangienwand weist mehrere Zellschichten auf (Unterschied lepto- sporangiate Farne, hier einschichtig). Bei einigen Arten der Psilotales fehlt eine echte Wurzel. Alle Arten sind mykotroph (Ernährung mittels Pilzsymbiose im Boden, Mykorrhiza). 1. Ordnung: Psilotales (Gabelfarne) 1.1 Systematik und Verbreitung Die Ordnung der Psilotales enthält nur 1 Familie, die Psilotaceae mit nur 2 Gattungen und 17 Arten (Psilotum 2 und Tmesipteris 15 Arten). Die Familie ist überwiegend tropisch verbreitet. 1.2 Morphologie 1.2.1 Habitus Die Arten der Psilotales sind ausschließlich krautige Pflanzen mit einem kräftigen, unterirdischen Kriechspross (Rhizom), das zahlreiche Rhizoide ausbildet. Echte Wurzeln fehlen. Die vollständige Reduktion der Wurzel wird hier als sekundäres, abgeleitetes Merkmal angesehen. Wie der Gametophyt ist auch der Sporophyt mykotroph, was erst die morphologische Reduktion der Wurzel erlaubte. Die oberirdischen sparrig dichotom verzweigten Sprossachsen weisen eine (angedeutete) Siphonostele mit einem holzigen Mark auf. Die unterirdischen Rhizome haben hingegen eine Protostele. 1.2.2 Blatt Arten aus den Psilotales haben ausschließlich schraubig angeordnete Mikrophylle. Bei Psilotum sind nur die Sporophylle Gabelblätter (im Unterschied zu den sterilen © PD DR. VEIT M. DÖRKEN, Universität Konstanz, FB Biologie Ophioglossidae 2 Polypodiopsida Blättern). Die Photosynthese erfolgt daher hauptsächlich über die chlorophyllreichen Sprossachsen (Rutenstrauch-Prinzip).

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. -

Vol. 21, No. 2., 357–372, 2012, Zagreb. The process of urbanization is one of the most extreme forms of anthropogenic habitat modifica- tion. Negative trends and their effects on the one hand, and concern for the preservation of bio- diversity and quality of city life on the other, are the initiators of urban flora research. The flora of urban areas in Croatia has not been the subject of sustained research and therefore floristic records for most of the larger cities are unknown. The research area is located in northwest Croatia in the city of Zagreb, on the right bank of the Sava River. In the area of Konopljenka and Pi{korovo a total of 351 taxa of vascular plants belonging to 81 families were recorded. Seven of them (2%) were pteridophytes (Equisetidae), two of them (0.6%) gymnosperms (Pinidae), and others were angio- sperms (Magnoliidae). Among angiosperms, 71 taxa (20.2%) belong to monocotyledons (superorder Lilianae) and the other 271 taxa (77.2%) from 65 families belong to other superorders of angio- sperms. -

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. They are arranged in the same order as listed in the fern checklist presented on pages 26 and 27. 2 Midrib Blade Pinnule(s) Frond (leaf) Pinna Petiole (leaf stalk) Parts of a fern frond, northern wood fern (p. -

Native Plant List, Pdf Format
Appendix A: City of Bellingham Native Plant List December 2020 The City of Bellingham Native Plant List (Figure 1) includes plant species that are native to Bellingham watersheds (Figure 2). The native plant list applies to all habitat types, including riparian, upland, and wetland areas. The list was developed using specimen records from the Consortium of Pacific Northwest Herbaria and Bellingham plant checklists curated by Don Knoke, a volunteer at the University of Washington Herbarium. To improve plant establishment and protect the genetic resources of our local plant populations, the City recommends using native plants that were grown from seeds or cuttings collected from the Puget Trough Ecoregion (Figure 3). Obtaining native plants grown from material collected from the Puget Trough Ecoregion will help ensure the plants are adapted to the unique environmental conditions of Bellingham watersheds and are genetically similar to our local plant populations. A more thorough discussion of the rational and selection process is provided in the City of Bellingham Public Works Department Native Plant Materials Selection Guidelines, December 2020. Figure 1.
