Anatomy

Summary of leaf anatomy (German)

Obere Epidermiszellen grösser als untere. 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 einer Reihe. Rechteckige Stützen. Kleine Interzellularen, oft dreieckig. Epidermiszellen aussen verholzt.

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 cells inside thin, peripheral thicker-walled (lignified). Guard cells externally rounded off. 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. Small sclerenchymatic sheath around vascular bundles with 1-2 cells. Vessels arrangement in vascular bundles in lateral position. Largest vessel in the bundle 20-50 μm. Cavities (intercellulars) between parenchyma cells absent. Crystals absent.

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.
