  • Nettles and the Romanian Traditions
    Nettle ( Urtica dioica ) – its role and its importance in the life of the Romanian people and in popular traditions A. Stroia, C.Cace, C.Costea, L. Libardea There isn’t a single person in Romania – from a small child to an 80 year old person, who, when asked: • „What is the nettle?”, or • „What is the nettle traditionally used for in Romania? Not to be able to offer a perfectly documented answer. But what would you say if the interlocutor you are asking these questions would answer: „When I hear the word nettle, it takes me back to my childhood, to the renowned “Nettle soup”, to the renowned “Mashed nettles”, “Nettles with garlic”, to the “pleasant, refined and special taste of the traditional Romanian dishes I have known as a child!” The nettle is a very well known plant in Romania, because it is used in the cuisine. For this reason, few think about its healing properties, to the fact that it can contribute to a better health. Its name in English, “nettle”, comes from the Dutch word “netel”, which means “needle”, due to the fact that upon touching, when the plant is young, it stings. In spite of this, nettles that are cooked or used as infusion no longer sting and have a pleasant taste. In Romania, as in the whole of Europe, North of Africa, Asia and North America, the nettle (Urtica dioica) is spread in uncultivated lands, in the plains, hillsides or mountains, on the edges of forests or roads, at the base of trees etc, being one of the many species of “spontaneous flora”.

    Pollination Ecology Summary Prof. em. Klaus Ammann, Neuchâtel [email protected] June 2013 Ohne den Pollenübertragungs-Service blütenbesuchender Tiere könnten sich viele Blütenpanzen nicht geschlechtlich fortpanzen. Die komplexen und faszinierenden Bestäubungsvorgänge bei Blütenpanzen sind Ausdruck von Jahrmillionen von Selektionsvorgängen, verbunden mit Selbstorganisation der Lebewesen; eine Sicht, die auch Darwin schon unterstützte. Bei vielen zwischenartlichen Beziehungen haben sich zwei oder auch mehrere Arten in ihrer Entwicklung gegenseitig beeinusst. Man spricht hier von sogenannter Coevolution.

  • Towards Resolving Lamiales Relationships
    Schäferhoff et al. BMC Evolutionary Biology 2010, 10:352 http://www.biomedcentral.com/1471-2148/10/352 RESEARCH ARTICLE Open Access Towards resolving Lamiales relationships: insights from rapidly evolving chloroplast sequences Bastian Schäferhoff1*, Andreas Fleischmann2, Eberhard Fischer3, Dirk C Albach4, Thomas Borsch5, Günther Heubl2, Kai F Müller1 Abstract Background: In the large angiosperm order Lamiales, a diverse array of highly specialized life strategies such as carnivory, parasitism, epiphytism, and desiccation tolerance occur, and some lineages possess drastically accelerated DNA substitutional rates or miniaturized genomes. However, understanding the evolution of these phenomena in the order, and clarifying borders of and relationships among lamialean families, has been hindered by largely unresolved trees in the past. Results: Our analysis of the rapidly evolving trnK/matK, trnL-F and rps16 chloroplast regions enabled us to infer more precise phylogenetic hypotheses for the Lamiales. Relationships among the nine first-branching families in the Lamiales tree are now resolved with very strong support. Subsequent to Plocospermataceae, a clade consisting of Carlemanniaceae plus Oleaceae branches, followed by Tetrachondraceae and a newly inferred clade composed of Gesneriaceae plus Calceolariaceae, which is also supported by morphological characters. Plantaginaceae (incl. Gratioleae) and Scrophulariaceae are well separated in the backbone grade; Lamiaceae and Verbenaceae appear in distant clades, while the recently described Linderniaceae are confirmed to be monophyletic and in an isolated position. Conclusions: Confidence about deep nodes of the Lamiales tree is an important step towards understanding the evolutionary diversification of a major clade of flowering plants. The degree of resolution obtained here now provides a first opportunity to discuss the evolution of morphological and biochemical traits in Lamiales.

  • Yellow Archangel Lamium – a Devil to Control!
    ALIEN PLANT INVADERS: Yellow Archangel Lamium – A Devil To Control! A series of articles on how to identify and manage some common invasive species on Salt Spring Island, by Jean Wilkinson, Stewardship Committee, Salt Spring Island Conservancy (former articles available on SSIC Web-site) The spread of invasive species is a very serious threat to our native flora and ecosystems, but we can help reduce the impacts of invasive plants by not planting them and by preventing and controlling infestations in our yards and neighbourhoods. In our region one of the most common and challenging invasive plants is Yellow Archangel, aka Dead-nettle. A type of Lamium native to Europe, Asia, and North Africa, it is often used in hanging baskets or sold as a low maintenance, fast- growing perennial ground-cover, easily adaptable to sun or shade. This description should trigger alarm bells! Such plants can quickly take over garden beds and invade nearby natural areas, and they’re difficult to control and remove. Avoiding this problem by planting non-invasive alternatives (see below) is the best policy, but established patches of Lamium and other invasive species can be removed with a bit of effort. Yellow Archangel is particularly problematic as it often spreads into undisturbed wooded areas, forming thick mats and smothering the native plants that provide habitat for wildlife. Large areas can be severely impacted by the dumping of a single hanging basket. Other Lamium varieties (eg L. purpureum) also escape gardens, so if you’re set on growing any of these, please keep them in a contained area, away from the edges of woods or meadows, and be sure to deadhead the flowers.

  • Barrowhill, Otterpool and East Stour River)
    Folkestone and Hythe Birds Tetrad Guide: TR13 D (Barrowhill, Otterpool and East Stour River) The tetrad TR13 D is an area of mostly farmland with several small waterways, of which the East Stour River is the most significant, and there are four small lakes (though none are publically-accessible), the most northerly of which is mostly covered with Phragmites. Other features of interest include a belt of trees running across the northern limit of Lympne Old Airfield (in the extreme south edge of the tetrad), part of Harringe Brooks Wood (which has no public access), the disused (Otterpool) quarry workings and the westernmost extent of Folkestone Racecourse and. The northern half of the tetrad is crossed by the major transport links of the M20 and the railway, whilst the old Ashford Road (A20), runs more or less diagonally across. Looking south-west towards Burnbrae from the railway Whilst there are no sites of particular ornithological significance within the area it is not without interest. A variety of farmland birds breed, including Kestrel, Stock Dove, Sky Lark, Chiffchaff, Blackcap, Lesser Whitethroat, Yellowhammer, and possibly Buzzard, Yellow Wagtail and Meadow Pipit. Two rapidly declining species, Turtle Dove and Spotted Flycatcher, also probably bred during the 2007-11 Bird Atlas. The Phragmites at the most northerly lake support breeding Reed Warbler and Reed Bunting. In winter Fieldfare and Redwing may be found in the fields, whilst the streams have attracted Little Egret, Snipe and, Grey Wagtail, with Siskin and occasionally Lesser Redpoll in the alders along the East Stour River. Corn Bunting may be present if winter stubble is left and Red Kite, Peregrine, Merlin and Waxwing have also occurred.

This research reflects the data available at the time this evaluation was conducted. Summary This evaluation was conducted largely based on the parent species Lamium maculatum. This is due to the potential for any given cultivar to revert back to the parent type as it grows and/or hybridize with itself or neighboring varieties to produce hybrid seed, some of which is likely to very closely resemble the parent plant. Lamium maculatum can be aggressive in garden beds. It has escaped cultivation to a relatively small degree, but seems to be limited to disturbed sites, i.e. it may not have the capacity to compete successfully with native plants in natural areas in Minnesota. As a nettle, and a member of the mint family, it can spread aggressively via vegetative propagation.

    FSC Nettlecombe Court Nature Review 2014 Compiled by: Sam Tuddenham Nettlecombe Court- Nature Review 2014 Introduction The purpose of this report is to review and share the number of different species that are present in the grounds of Nettlecombe Court. A significant proportion of this data has been generated by FSC course tutors and course attendees studying at Nettlecombe court on a variety of courses. Some of the data has been collected for the primary purpose of species monitoring for nationwide conservation charities e.g. The Big Butterfly Count and Bee Walk Survey Scheme. Other species have just been noted by members or staff when out in the grounds. These records are as accurate as possible however we accept that there may be species missing. Nettlecombe Court Nettlecombe Court Field Centre of the Field Studies Council sits just inside the eastern border of Exmoor national park, North-West of Taunton (Map 1). The house grid reference is 51o07’52.23”N, 32o05’8.65”W and this report only documents wildlife within the grounds of the house (see Map 2). The estate is around 60 hectares and there is a large variety of environment types: Dry semi- improved neutral grassland, bare ground, woodland (large, small, man –made and natural), bracken dominated hills, ornamental shrubs (lawns/ domestic gardens) and streams. These will all provide different habitats, enabling the rich diversity of wildlife found at Nettlecombe Court. Nettlecombe court has possessed a meteorological station for a number of years and so a summary of “MET” data has been included in this report.

MORPHOLOGICAL, ANATOMICAL AND CYTOLOGICAL STUDIES ON ENDEMIC LAMIUM PISIDICUM PELĐN BARAN 1* AND CANAN ÖZDEMĐR 2 1Uşak University, Faculty of Science and Art, Department of Biology, 1 Eylül Campus, D2Academic Block, Uşak 64200-Turkey; 2Celal Bayar University, Faculty of Art and Science, Department of Biology, Muradiye Campus, Muradiye-Manisa 45140-Turkey *Corresponding author’s e-mail: [email protected] Abstract Morphological and anatomical features of endemic Lamium pisidicum R. Mill (Lamiaceae) were studied. L. pisidicum is a perennial with a taproot system. The stem is ascending to erect in position and clearly quadrangular in shape. The leaves are ovate to broadly ovate or rarely reniform in shape. Verticillasters are 2-14 flowered. The corolla is pinkish-purple to mauve and the upper lip is deeply bifid and the tube is without annulus. The stigma is bifid. The stamens are didynamus. Anatomically, spring and autumn woods are distinguishable in the root structure of the perennial taxon. There is a well- developed collenchymatous layer at the corners of the stem and a pith hollow in the centre. In the petiole cross-section, 1-2 layered collenchyma layer is located at the corners while 3 central vascular bundles are located in the middle and 1 vascular bundle at the petiolar wings. The leaf is bifacial. Each anther is of two thecae and each theca is of 2 pollen sacs. Pollen type is trizonocolpate and pollen shape is spheroidal. The cross-section of seed is triangular. Glandular hairs distributed on the plant species are classified into 2 main types, peltate and capitate.

Bremer, P. Cantino, J. Chau, J. L. Clark, B. Drew, P. Garnock- Jones, S. Grose (Heydler), R. Harley, H.-D. Ihlenfeldt, B. Li, L. Lohmann, S. Mathews, L. McDade, K. Müller, E. Norman, N. O’Leary, B. Oxelman, J. Reveal, R. Scotland, J. Smith, D. Tank, E. Tripp, S. Wagstaff, E. Wallander, A. Weber, A. Wolfe, A. Wortley, N. Young, M. Zjhra, and many others [estimated 25 families, 1041 genera, and ca. 21,878 species in Lamiales] The goal of this project is to produce a working infraordinal classification of the Lamiales to genus with information on distribution and species richness. All recognized taxa will be clades; adherence to Linnaean ranks is optional. Synonymy is very incomplete (comprehensive synonymy is not a goal of the project, but could be incorporated). Although I anticipate producing a publishable version of this classification at a future date, my near- term goal is to produce a web-accessible version, which will be available to the public and which will be updated regularly through input from systematists familiar with taxa within the Lamiales. For further information on the project and to provide information for future versions, please contact R. Olmstead via email at [email protected], or by regular mail at: Department of Biology, Box 355325, University of Washington, Seattle WA 98195, USA.
