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 unten eingebettet. Leitbündelhülle verholzt.

Summary of stem anatomy (German)

Leitbündel in einer Reihe. Epidermiszellen 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 thick-walled all around. Large vascular bundles arranged in 2-3 peripheral rows. Chlorenchyma in tangentially enlarged groups. Sclerenchyma in a large, peripheral continuous belt (> 3 cells). Cells thick-walled. Girders square, rectangular or conic. Girders tangentially enlarged. Sclerenchymatic sheath around vascular bundles large, 3 to x cells. Largest vessels in vascular bundles in lateral position. Largest vessel in the bundle 20-50 μm. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles.
