Synthesis

Species description (© Flora Helvetica 2018)

70-150(-200) cm hoch, bläulich bereift. Blätter 5-15 mm breit, flach, allmählich zugespitzt, kahl oder fein behaart. Blatthäutchen kurz und gestutzt, zudem kleine, kahle Blattöhrchen. Blütenstand eine dichte, 5-20 cm lange, schon zur Blütezeit nickende Ähre. Ährchen 2blütig, oft mit verkümmerter dritter Blüte. Deckspelzen scharf gekielt, mit 4-8 cm langer Granne. Hüllspelzen sehr schmal, spitz oder mit kurzer Granne.

Anatomy

Summary of leaf anatomy (German)

Obere Epidermiszellen gleich gross wie untere. Epidermiszellen aussen verholzt. 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 mit Rippen. Leitbündel in einer Reihe. Konische Stützen. Kleine Interzellularen, oft dreieckig. Epidermiszellen verholzt. Chlorenchyma in tangential verlängerten Gruppen.

Description

Culm-diameter 1-2 mm, wall thin, radius of culm in relation to wall thickness approximately 1:0.25 or < 0.25. Outline circular wavy. Culm-center hollow and surrounded by a few thin-walled, not lignified cells. Epidermis-cells thick-walled all around. Large vascular bundles arranged in one peripheral row. Chlorenchyma in tangentially enlarged groups. Sclerenchyma in a small, peripheral continuous belt (< 4 cells). Cells medium thick-walled. Girders square, rectangular or conic. Small sclerenchymatic sheath with 1-2 cells around vascular bundles. Largest vessels in vascular bundles in lateral position. Largest vessel in the bundle 20-50 μm. Cavities (intercellulars) between parenchyma-cells present, small, often triangular.
