Anatomy

Summary of stem anatomy (German)

Umriss rund gewellt. Leitbündel diffus verteilt. Epidermiszellen nicht verholzt.

Description

Culm-diameter 2-5 mm, wall very large, radius of culm in relation to wall thickness approximately 1:0.75. Outline circular wavy. Center hollow and surrounded by many large thin-walled, not lignified cells. Without cortex/cylinder separation. Epidermis cells thin-walled all around. Large vascular bundles distributed in the whole culm. Sclerenchymatic sheath around vascular bundles one-sided large, 2-4 cells, centripetal. Vessel arrangement horseshoe-like. Largest vessel in the bundle 20-50 μm. Cavities (intercellulars) between parenchyma-cells small, often triangular.

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.
