Summary of leaf anatomy (German)

Obere Epidermiszellen gleich gross wie untere. Verbindungs-Steg zwischen oberer und unterer Epidermis homogen verholzt. Leitbündel im Verbindungs-Steg in der Mitte eingebettet. Leitbündelhülle verholzt.

Summary of stem anatomy (German)

Umriss rund oder oval. Leitbündel in einer Reihe. Epidermiszellen verholzt. Chlorenchyma in tangential verlängerten Gruppen.

Description

Culm-diameter 1-2 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 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 bilateral, large at both radial ends of 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. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles.
