Summary of leaf anatomy (German)

Obere Epidermiszellen gleich gross wie untere. Epidermiszellen aussen verholzt. Punktuelle Versteifungselemente am Blattrand und bei der Blattrippe. Leitbündel freistehend. Leitbündelhülle nicht verholzt.

Summary of stem anatomy (German)

Umriss rund gewellt. Leitbündel in einer Reihe. Epidermiszellen verholzt. Chlorenchyma in peripheren runden, ovalen oder rechteckigen 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 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 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. Cavities (intercellulars) between parenchyma-cells present, small, often triangular. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles.
