  abstract  = {Rubus pseudoglotta Drenckhahn \& W. Jansen ist eine tetraploide Brombeerart aus der Sektion Corylifolii (Serie Subradula), die bisher zum Variabilit{\"a}ts-Spektrum von R. phylloglotta (Frid.) {\AA}. Gust. gez{\"a}hlt wurde. Charakteristische Merkmale sind die 4 (3-5)-z{\"a}hligen Bl{\"a}tter mit obovaten Endbl{\"a}ttchen mit kurzer (ca. 1 cm) abgesetzter Spitze, kurzhaariger Blattoberseite und f{\"u}hlbar behaarter gr{\"u}ner Blattunterseite. Die flach bogigen, teils klimmenden Sch{\"o}sslinge sind {\"u}berwiegend stumpfkantig, gr{\"u}n bis r{\"o}tlichbraun, schwach behaart und reichlich mit 2-4 (5) mm langen, geraden bis schwach gekr{\"u}mmten Stacheln und kleineren Stacheln, Stachelh{\"o}ckern, Stieldr{\"u}sen und Borsten besetzt. Die Bl{\"u}tenstiele sind mit 2-8 (pro cm) schlanken, geraden bis leicht gekr{\"u}mmten Stacheln (1-2 mm lang) und zahlreichen Stieldr{\"u}sen (teils bis 0,6 mm lang) besetzt. Die Sippe w{\"a}chst bevorzugt an Straßen- und Wegr{\"a}ndern und in Hecken. Die bekannt gewordenen Fundstellen erstrecken sich von Rendsburg bis in das Umfeld von Kiel, nordw{\"a}rts bis zu den d{\"a}nischen Inseln Alsen und F{\"u}nen. Unsere Untersuchungen zeigen weiterhin, dass R. phylloglotta bisher nicht in Schleswig-Holstein/Deutschland nachgewiesen wurde. Ob R. phylloglotta {\"u}berhaupt außerhalb der Insel T{\aa}singe in D{\"a}nemark vorkommt, bedarf weiterer Nachforschungen.},

  abstract  = {Forum Geobotanicum is an electronic journal devoted to disseminate information concerning geographical distribution, ecology, morphology, taxonomy and conservation of vascular plants in the European Union with a main focus on middle Europe. It covers from molecular biology to environmental aspects. The focus is to publish original papers, reviews and announcements for the educated generalist as well as the specialist in this broad field. Forum Geobotanicum does not aim to supplant existing paper journals, but will be much more flexible in format, publication time and world-wide distribution than paper journals. Many important studies are being currently published in local journals and booklets and some of them are published privately. Hence, these studies will become aware to only a limited readership. Forum Geobotanicum will encourage authors of such papers to submit them as special issues of the journal. Moreover, the journal is planning to build up an E-mail-address section to support communication between geobotanists in Europe. The editors are optimistic that this electronic journal will develop to a widely used communication forum that will help to stimulate activities in the entire field of geobotany in middle Europe. To overcome problems of long term archivation and effective taxonomic publication of articles published electronically in Forum Geobotanicum, print versions of each volume of the journal and appropriate digital storage devices will be delivered freely to selected university libraries and state libraries in middle Europe.},
