Anatomy

Summary of stem anatomy (German)

Umriss rund oder oval. Leitbündel diffus verteilt. Konische Stützen. Epidermiszellen verholzt.

Description

Culm-diameter 2-5 mm, center full, radius of culm in relation to wall thickness 1:1. Outline circular with a smooth surface. Outline circular, with rips. Culm-center full, containing unlignified cells. Epidermis smooth. Epidermis cells thin-walled all around. Chlorenchyma present, continuous peripheral belt with unlignified round cells (like a large cortex). Groups of sclerenchyma square or rectangular. Vascular bundles collateral closed. Sclerenchymatic sheath around vascular bundles one-sided large, 2-4 cells, centripetal. Vessel arrangement irregularly grouped or distributed. 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.
