Anatomy

Summary of stem anatomy (German)

Umriss rund oder oval. Leitbündel diffus verteilt. Kleine Interzellularen, oft dreieckig.Epidermiszellen nicht verholz

Description

Culm-diameter 2-5 mm, center full, radius of culm in relation to wall thickness 1:1. Outline circular with a smooth surface. Culm-center full, containing unlignified cells. Without cortex/cylinder separation. Culm without endodermis but with a sheath of lignified cells around the center. Epidermis smooth. Epidermis cells thin-walled all around. Guard cells externally rounded off; difficult to recognize. Large vascular bundles distributed in the whole culm. Chlorenchyma present, continuous peripheral belt with unlignified round cells (like a large cortex). Vascular bundles concentric, phloem in the center. Small sclerenchymatic sheath around vascular bundles with 1-2 cells. Vessel arrangement irregularly grouped or distributed. 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.
