The tube pipes grass ( Molinia arundinacea ) is a plant from the genus of Molinia ( Molinia ) within the family of grasses (Poaceae). Other common names are large pipe grass or tall pipe grass .
description
Vegetative characteristics
The pipe pipe grass is a perennial herbaceous plant and reaches heights of 100 to 200, rarely up to 250 centimeters. This grass forms large clumps through numerous renewal shoots that grow outside the lowest leaf sheaths . In the lower part of the stalk there are two to three knots that are close to one another and another 2 to 4 centimeters apart . The topmost stalk spans almost the entire length of the stalk and is leafless.
The leaf sheaths are bare. A thick lash line made of 0.5 millimeter long hair forms the ligule . The tough leaf blades are 40 to 60 centimeters long and 8 to 12, rarely up to 18 millimeters wide. The leaves turn bright orange-brown in autumn and are then visible from afar.
Generative characteristics
The flowering period extends from July to September. The paniculate inflorescences are 30 to 60 centimeters long and are loose and spread out to the anthesis , with the side branches 8 to 20 centimeters long. The 6 to 9 millimeters long and mostly purple spikelets contain two to four flowers.
The number of chromosomes is 2n = 90.
Occurrence
The reed pipe grass is widespread in Europe and is also found in the Caucasus.
In Germany, the pipe pipe grass occurs scattered in the southern part. It rises in the Black Forest to an altitude of 1280 meters and in the Alps up to 2000 meters. In the Allgäu Alps in Bavaria, it rises on the Höfats on the Falkenberg southwest slope above the Dietersbacher Alpe to around 1750 meters above sea level. In Austria it is distributed in all federal states from the colline to subalpine altitude .
As a location, alternatively moist to alternately dry , lean, base-rich and often calcareous, low -humus loam or impermeable silicate soils are preferred; but it also grows on gravel. It thrives in deciduous and coniferous forests, on forest edges, and often on steep slopes. Large areas of snow can slide off the depressed leaves of this species in winter (sliding slopes). The species often occurs in the Cirsio tuberosi-Molinietum arundinaceae, but also in societies of the Erico-Pinion, Mesobromion, Caricion ferrugineae, Quercion roboris or the order Origanetalia associations.
Systematics
Molinia arundinacea cupboard is sometimes considered a synonym of Molinia caerulea (L.) Moench , which means that both are considered as one species.
use
The pipe whistle grass is often grown in botanical gardens.
