Hairy Wood-rush ( Luzula pilosa )

The Hairy Wood-rush ( Luzula pilosa ), also known as Hair Hairy Wood-rush or Marbel, is a plant from the family of Rushes. The plant forms along with other early bloomers such as forest violets, wood anemone, lesser celandine or wood - sorrel spring aspect in sparse, acidophilous forests.

Distribution and location

It is widespread in Europe and Asia to Western Siberia from the plains to altitudes of 2000 meters above sea level.

The Wood-rush grows sour in light deciduous and coniferous forests, nutrient poor to medium sites. Before the leaves is, along with several other early bloomers the spring aspect of the herb layers. Often it also grows along forest paths or forest edges.

Description

The Hairy Wood-rush is a perennial, overwintering green Hemikryptophyt, achieved the stature heights between 15 and 40 centimeters. The bins greenhouse grows in small clumps, which in turn can develop loose grass and rarely makes short runners. The thin stems grow upright. The undergraduate, grassy and glossy leaves are 4 to 12 millimeters wide and ciliated close to the edge. The bracts are very short and always significantly shorter than the inflorescence.

The loose, upright and Vielblütige inflorescence is a Spirre with upright arching branches to fruit time. The flowers are individually. The almost equally long bloom ( perianth ) are about 3 mm long, lanceolate pointed, maroon and at the edge wide hautrandig. The stylus wear three greenish white scars. The last yellow-green capsule fruit is conical blunt. It is longer than the perigone and constricted and narrowed above the center. The shiny brown seeds are between 2.5 and 3.5 millimeters long and each have a crescent-shaped appendage ( Elaiosom ).

Chromosome number: 2n = 66

Ecology

The Hairy Wood-rush is a Hemikryptophyt and a half rosette plant or an evergreen plant Horst. The Blattrandbehaarung is caused by edge strips detachment. The leaf rosettes serve as a water collector. The Hairy Wood-rush is a deep shade to full shade plant. Your ecological emphasis is on fresh, moderately acidic, nitrogen-poor to moderate nitrogen-rich soils. It is a characteristic plant of acidophilous beech forests ( Fagetalia sylvaticae ), acidophilous oak forests ( Quercetalia robori - petraeae ) and of pine, spruce forests ( Vaccinio - Piceetalia ).

The opening of the flowers takes place only in the male stage; pollination is done by the wind ( Anemogamie ). Bloom time is from March to May

The fruits are loculicidal capsules. The fruit falls ripe stalks to the ground. The plant is a Selbstaussäer. The further spread of diasporas via ants ( myrmecochory ). To this end, it has the seeds of special oil and sugary bodies ( elaiosomes ) that attract ants. Fruit ripening from June to July.

Vegetative propagation is done by underground runners
