Summary of stem anatomy (German)

Umriss rund oder oval. Leitbündel diffus verteilt. Kleine Interzellularen, oft dreieckig. Epidermiszellen nicht verholzt.

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. Culm without endodermis but with a sheath of lignified cells around the center. Epidermis smooth. Epidermis cells thin-walled all around. Epidermis with hairs. Large vascular bundles distributed in the whole culm. Chlorenchyma present, continuous peripheral belt with unlignified round cells (like a large cortex). Vascular bundles collateral closed. Small sclerenchymatic sheath around vascular bundles with 1-2 cells. Sheath around vascular bundles absent or not lignified. Vessels arrangement in vascular bundles in lateral position. Largest vessel in the bundle 20-50 μm. Cavities (intercellulars) between parenchyma cells absent. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles. Crystals as raphids or styloids.
