Summary of stem anatomy (German)

Umriss stumpf-dreieckig. Leitbündel diffus verteilt. Kleine Interzellularen, oft dreieckig. Epidermiszellen nicht verholzt.

Description

Culm-diameter 1-2 mm, center full, radius of culm in relation to wall thickness 1:1. Outline circular with a smooth surface. Outline triangular, obtusely. Culm-center full, containing unlignified cells. Epidermis smooth. Epidermis cells thin-walled all around. Guard cells with externally acute ledge. Large vascular bundles arranged in 2-3 peripheral rows. Chlorenchyma present, continuous peripheral belt with unlignified round cells (like a large cortex). Sclerenchyma belt absent. Groups of sclerenchyma at the periphery, round. Vascular bundles collateral closed. Small sclerenchymatic sheath around vascular bundles with 1-2 cells. Vessels arrangement in vascular bundles in lateral position. Largest vessel in the bundle small, < 20μm. Cavities (intercellulars) between parenchyma-cells small, often triangular. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles.
