The many-flowered grove ( Luzula multiflora ) is a species of the rush family . The long-lived seeds are spread by ants .

Identifying features

The multi-flowered grove grows densely grassed to clumpy , so does not form runners, and is about 15 to 40 cm tall. The upright inflorescence is composed of clearly stalked spikelets . The perigone of each individual flower is pale yellowish brown, then almost always brown in color with age. The outer tepals are up to 3.8 mm long and have a narrow or wide skin edge. The anthers are about twice as long as the stamens . The stylus is no longer than 1 mm, with the approximately 2 mm long scars falling off quickly. The basal leaves are about 3.5 mm wide. The seeds have an appendage about 0.5 mm long.

The number of chromosomes is 2n = 24, less often 12, 14, 28, 36.

Occurrence

Luzula multiflora mostly colonizes fresh to moist sandy and silicate grasslands. It has its main occurrence in the plant formation of the dwarf shrub heaths and nebulas and a secondary occurrence in light, acidic deciduous and coniferous forests with nutrient-poor soils. It can also be found in heaths, on extensively used wet meadows and in fens . In terms of plant sociology, it can best be assigned to the order Atropetalia, the order Caricetalia fuscae and the class Molinio-Arrhenatheretea . The plant is moderately common all over Germany. Their distribution area is circumpolar in the northern and southern hemispheres.
