Anatomy
Summary of stem anatomy (German)
Umriss rund mit Rippen. Leitbündel in einer Reihe. Epidermiszellen verholzt. Epidermiszellen nicht verholzt. Chlorenchyma in tangential verlängerten Gruppen.Description
Culm-diameter 1-2 mm, wall thin, radius of culm in relation to wall thickness approximately 1:0.25 or < 0.25., Outline circular wavy. Culm-center hollow and surrounded by a few thin-walled, not lignified cells. Epidermis-cells thin-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 20-50 μm. Cavities (intercellulars) between parenchyma-cells present, small, often triangular. Artifacts on material from herbaria, e.g. compressed and deformed culms or exaggerated distinct rips.Distribution map
