Agrostis capillaris

Red bentgrass

The Red bentgrass ( or red bentgrass ) ( Agrostis capillaris ) is a very variable bluegrass from the Gramineae family. It is used as fodder and ornamental turf grass, especially in the Alpine area, because it is quite undemanding. Agrostis is the name of various agricultural grasses of antiquity and is derived from the Greek agros for arable. capillaris is fine, or hair -like.

Occurrence

The Red bent grass blooms in June and July and is on sand and silicate dry grasslands, occurs in heathlands, in light oak and pine forests and dry waste places. It avoids calcareous soils and is widely used throughout Germany. One can find in the other parts of Europe, as well as in West Asia. In Australia, New Zealand, North and South America, it is considered as a neophyte.

Identifying

The Red bentgrass is about 20 to 60 cm high and is short, suckers and therefore grows horst -like. Your flat, 2-4 mm broad leaves are green, the upper side and lower side ribbed mat. They are very well bare and youngest leaves appear rolled when cut in cross section. The ligule is only up to 1 mm long. The 2-3 cm long spikelets are in a loose panicle, are flowered, red-violet colored, have no awn, appear laterally compressed and have more or less distinctly keeled glumes. Overall, each of spikelets on 2 glumes that are longer than lemma. These are not hairy. The Red bent grass is very rich in form. However, the subspecies mentioned in many books have no systematic value because there are smooth transitions between the different populations.

Ecology

The Red bent grass is a perennial grass with Horst Hemikryptophyt and a short underground runners.

The grass is pollinated by the wind also ( anemophily ). The pollen is released in the afternoon, making a bastardization with other Agrostis is limited, the morning release the pollen. The Red bentgrass is a cause of hay fever. Bloom time is from June to August.

The Karypsen the type called Spelzfrüchte because they are enveloped by glumes. This allows their wind propagation ( Anemochorie ) as a balloon pilot and the floating spread as Regenschwemmling. Fruit ripening from July to September. The seeds are long-lasting light to germinate.

Asexual reproduction occurs by stolons.

System

It used to be also used other names:

• Agrostis tenuis
• Agrostis vulgaris
