Anatomy

Summary of leaf anatomy (German)

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

Summary of stem anatomy (German)

Umriss rund oder oval. Leitbündel in mehreren Reihen. Epidermiszellen verholzt. Chlorenchyma in peripheren runden, ovalen oder rechteckigen Gruppen.

Description

Culm-diameter 2-5 mm, center full, radius of culm in relation to wall thickness 1:1. Outline circular with a smooth surface. Culm-center full, containing unlignified cells. Epidermis- cells thin-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. Sclerenchymatic sheath around vascular bundles large, 3 to x cells. 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.
