Anatomy

Summary of stem anatomy (German)

Umriss rund mit Rippen. Leitbündel in mehreren Reihen. Konische Stützen. 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, with rips. Culm-center hollow and surrounded by many large thin-walled, not lignified cells. Epidermis-cells thin-walled all around. Large vascular bundles arranged in one peripheral row. Chlorenchyma in tangentially enlarged groups. Sclerenchyma in a large, peripheral continuous belt (> 3 cells). Cells medium thick-walled. Girders square, rectangular or conic. 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. Artifacts on material from herbaria, e.g. compressed and deformed culms or exaggerated distinct rips.
