Anatomy
Summary of leaf anatomy (German)
Obere Epidermiszellen grösser als untere. Epidermis mit Papillen. Verbindungs-Steg zwischen oberer und unterer Epidermis aus verholzten und nicht verholzten Zellen. Leitbündel im Verbindungs-Steg unten eingebettet. Leitbündelhülle verholzt.Summary of stem anatomy (German)
Umriss exakt dreieckig. Leitbündel in mehreren Reihen. Rechteckige Stützen. Epidermiszellen verholzt. Epidermiszellen mit Papillen.Description
Culm-diameter 1-2 mm, wall large, radius of culm in relation to wall thickness approximately 1: 0.5. Outline triangular, acutely. Culm-center hollow and surrounded by many large thin-walled, not lignified cells. Epidermis papillous (bulliform). Large vascular bundles arranged in one peripheral row. Small or rudimentary vascular bundles within the chlorenchyma. Chlorenchyma in round, oval, square or rectangular groups. Sclerenchyma belt absent. Groups of sclerenchyma square or rectangular. Vascular bundles collateral closed. Sclerenchymatic sheath around vascular bundles circular large, 3 to x cells. Vessels arrangement in vascular bundles in lateral position. Largest vessel in the bundle 20-50 μm. Cavities (intercellulars) between parenchyma-cells small, often triangular. Cavities (intercellulars) and aerenchyma in any other form. Crystals absent.Distribution map

- Disclaimer
InfoFlora compiles information on protected species as accurately as possible, taking it from the respective cantonal laws. In some cases, however, it was not possible to use the plant names as listed in the original text, but an interpretation of their taxonomy or nomenclature was necessary. The exact meaning of the categories „completely protected“ and „partially protected“ differs among the cantons.
InfoFlora cannot guarantee that the information on the protection status is correct and complete. In case of doubts, we recommend to look up the texts of the respective cantonal law.

Conservation
Threats and measures
Drainage, Austrocknung
Keine weitere Entwässerung
Wasserhaushalt stabilisieren und evtl. lokal leicht Vernässen
Aufgabe der traditionellen Streunutzung
Extensive Bewirtschaftung weiterführen
mehrjährige Bestände alle 2 Jahre im Herbst mähen
Schnittgut entfernen
Bewirtschaftungs- verträge
Verbuschung
Entbuschen
Beweidung, Eutrophierung
Höchstens extensiv beweiden
evtl. einzäunen
grosse Pufferzonen schaffen
Überbauung, Aufschüttung, Umwandlung in Landwirtschaftsland
Keine weiteren Flächenverluste zulassen
Wenige, isolierte Populationen, in der Schweiz sehr kleines Verbreitungsgebiet.
Schutz inkl. angemessener Pufferzonen (z. B. Ortsplanung)
regelmässige Bestandeskontrollen
Dauerflächen-Beobachtung
bestehende Schutz und Förderungsmassnahmen weiterführen, Verstärkung bestehender Populationen und Ansiedlung neuer Populationen durch Anpflanzung (nach Zwischenvermehrung)
