Anatomy

Summary of stem anatomy (German)

Umriss rund mit Rippen. Leitbündel in einer Reihe. Rechteckige Stützen. Kleine Interzellularen, oft dreieckig. Epidermiszellen verholzt. Chlorenchyma in peripheren runden, ovalen oder rechteckigen Gruppen.

Description

Culm-diameter 2-5 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 many large thin-walled, not lignified cells. Epidermis-cells thick-walled all around. 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 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.
