Species description (© Flora Helvetica 2018)
Unterscheidet sich von A. s. subsp. sativa durch folgende Merkmale: nur bis 1 m hoch, Rispe einseitswendig. Ährchen bei Reife leicht zerfallend. Deckspelze an der Spitze mit 2 feinen, 3-5 mm langen, grannigen Spitzen (Unterschied zu A. fatua), auf dem Rücken mit 3-6 cm langer Granne, in der unteren Hälfte mit 2-6 mm langen, geraden, zuletzt braunen Haaren. Abbruchstelle der Deckspelze schief.Flowering period (© Flora Helvetica 2018)

Anatomy
Summary of stem anatomy (German)
Umriss rund oder oval. Leitbündel in einer Reihe. Kleine Interzellularen, oft dreieckig. Epidermiszellen verholzt. Chlorenchyma in peripheren runden, ovalen oder rechteckigen 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 with a smooth surface. 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 round, oval, square or rectangular groups. Sclerenchyma in a large, peripheral continuous belt (> 3 cells). Cells 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.Distribution map
