Summary of stem anatomy (German)

Umriss rund oder oval. Leitbündel in einer Reihe. Kleine Interzellularen, oft dreieckig. Grosse, unregelmässige Intercellularen. Epidermiszellen aussen verholzt.

Description

Culm-diameter 0.5-1 mm, Outline circular with a smooth surface. Culm-center full, containing unlignified cells. Guard cells with externally acute ledge. Large vascular bundles arranged in one peripheral row. Chlorenchyma present, continuous peripheral belt with unlignified round cells (like a large cortex). Sclerenchyma belt absent. Vascular bundles collateral closed. 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 round, oval or radial. Cell contents as slime or phenols in isolated cells.
