Agropyron fragile (Roth) P.Candargy
Agropyron fragile is a grass.
Agropyron fragile was already described and the name validly published by Albrecht Wilhelm Roth. It was PalÃ©ologos C. Candargy, however, who reclassified it into todays valid botanical systematics .
The grasses reach heights of to 100 centimetres and are comparatively fast-growing and long-lived. They have a erect habit and have an upright habit and spread slowly. The main growing season is in spring and autumn.
Agropyron fragile is deciduous. The dark-green, simple leaves are alternate. They are linear with entire margins and parallel venation. The foliage is porous.

The grasses produce an abundance of brown caryopses in summer.
