  • 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.

Summary of stem anatomy (German)

Umriss rund oder oval. Leitbündel in einer Reihe. Kleine Interzellularen, oft dreieckig. Epidermiszellen verholzt. Chlorenchyma in tangential verlängerten Gruppen.

Description

Culm-diameter 1-2 mm, wall large, radius of culm in relation to wall thickness 1:0.5. Outline circular with a smooth surface. Outline circular with a smooth surface. Culm-center hollow and surrounded by a few thin-walled, not lignified cells. Epidermis with hairs. Large vascular bundles arranged in 2-3 peripheral rows. Chlorenchyma in round, oval, square or rectangular groups. Sclerenchyma in a large, peripheral continuous belt (> 3 cells). Cells 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. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles.
