Anatomy
Summary of stem anatomy (German)
Umriss rund gewellt. Leitbündel diffus verteilt. Kleine Interzellularen, oft dreieckig. Epidermiszellen verholzt.Description
Culm-diameter 2-5 mm, center full, radius of culm in relation to wall thickness 1:1. Outline circular wavy. Culm-center full, containing unlignified cells. Epidermis-cells thin-walled all around. Large vascular bundles arranged in 2-3 peripheral rows. Chlorenchyma absent. Sclerenchyma in a small, peripheral continuous belt (< 4 cells). Cells medium thick-walled. Sclerenchymatic sheath around vascular bundles large, 3 to x cells. Largest vessels in vascular bundles in lateral position. Largest vessel in the bundle 20-50 μm. Cavities (intercellulars) between parenchyma-cells present, small, often triangular.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.
