Summary of leaf anatomy (German)

Obere Epidermiszellen grösser als untere. Versteifungselemente linienförmig am Blattrand.Verbindungs-Steg zwischen oberer und unterer Epidermis homogen verholzt. Leitbündel im Verbindungs-Steg in der Mitte eingebettet. Leitbündelhülle verholzt.

Summary of stem anatomy (German)

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

Description

Culm-diameter 0.5-1 mm, center full, radius of culm in relation to wall thickness 1:1. Outline oval. Culm-center full, containing unlignified cells. Epidermis papillous (bulliform). Epidermis cells inside thin, peripheral thicker-walled (lignified). Guard cells externally rounded off. Large vascular bundles arranged in one peripheral row. Chlorenchyma in round, oval, square or rectangular groups. Sclerenchyma belt absent. Groups of sclerenchyma square or rectangular. 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. Cavities (intercellulars) between parenchymacells round, oval or radial. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles. Crystals absent.
