Summary of leaf anatomy (German)

Obere Epidermiszellen grösser als untere. Punktuelle Versteifungselemente am Blattrand und bei der Blattrippe. Verbindungs-Steg zwischen oberer und unterer Epidermis homogen verholzt. Leitbündel im Verbindungs-Steg unten eingebettet. Leitbündelhülle verholzt.

Summary of stem anatomy (German)

Umriss rund oder oval. Leitbündel in mehreren Reihen. Konische Stützen. Grosse, unregelmässige Intercellularen. Epidermiszellen aussen verholzt.

Description

Culm-diameter 1-2 mm, wall very large, radius of culm in relation to wall thickness approximately 1: 0.75. Culm-center hollow and surrounded by many large thin-walled, not lignified cells. Epidermis cells inside thin, peripheral thicker-walled (lignified). Guard cells with externally acute ledge. Large vascular bundles arranged in 2-3 peripheral rows. Chlorenchyma absent. Sclerenchyma belt absent. Groups of sclerenchyma square or rectangular. Vascular bundles collateral closed. Small sclerenchymatic sheath around vascular bundles with 1-2 cells. Largest vessel in the bundle small, < 20μm. Cavities (intercellulars) between parenchyma cells absent. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles. Cell contents as slime or phenols in isolated cells.
