Anatomy

Summary of leaf anatomy (German)

Obere Epidermiszellen grösser als untere. Epidermis mit Papillen.Verbindungs-Steg zwischen oberer und unterer Epidermis aus verholzten und nicht verholzten Zellen. Leitbündel im Verbindungs-Steg in der Mitte eingebettet. Leitbündelhülle nicht verholzt.

Summary of stem anatomy (German)

Umriss rund gewellt. Leitbündel in mehreren Reihen. Kleine Interzellularen, oft dreieckig. Epidermiszellen verholzt.

Description

Culm-diameter 1-2 mm, wall large, radius of culm in relation to wall thickness 1:0.5. 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 absent. Sclerenchyma in a large, peripheral continuous belt (> 3 cells). Cells medium thick-walled. 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.
