Anatomy
Summary of stem anatomy (German)
Umriss rund oder oval. Leitbündel in einer Reihe. Epidermiszellen verholzt. Chlorenchyma in tangential verlängerten Gruppen.Description
Culm-diameter 0.5-1 mm, wall very large, radius of culm in relation to wall thickness approximately 1:0.75. Outline circular with a smooth surface. Culm-center hollow and surrounded by many large thin-walled, not lignified cells. Epidermis-cells thick-walled all around. Large vascular bundles arranged in one peripheral row. Chlorenchyma in round, oval, square or rectangular groups. Sclerenchyma in a large, peripheral continuous belt (> 3 cells). Cells medium thick-walled. Girders square, rectangular or conic. Small sclerenchymatic sheath with 1-2 cells around vascular bundles. Largest vessels in vascular bundles in lateral position. Largest vessel in the bundle small, < 20μm. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles.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.
