Components of the flower of a grove

The wood-rush ( Luzula ), also known as grove rushes or regionally Marbel called, are a genus in the family of the Juncaceae (Juncaceae). It includes around 115 species worldwide . These are mainly characterized by long, whitish and soft hairs on the leaf blades and leaf sheath mouths.

Distribution and location

Grove cornices are common in the temperate and arctic regions of both hemispheres (cosmopolitan). The focus of their diversity is in Europe and Asia . In the tropics , their occurrence is limited to the higher elevations of the mountains. In contrast to the rushes ( Juncus ), the species of the genus Luzula prefer drier soils and shady locations such as forests and bushes.

description

Grove rims are herbaceous plants of several years . Most species are clump- shaped. They often form short rhizomes or, less often, stolons . The leaves are basal. The stem leaves, if present, are usually reduced. The leaf arrangement is three lines. The leaf blades are grass-like and flat, rarely runny. The leaf sheaths are always closed. With few exceptions, the leaf margins and vaginal mouths are long and softly ciliate. The mouth of the vagina is not eyed.

The inflorescence is a spiral , a modified form of the panicle . The marginal or lower flowers are petiolated the longest. The central or upper ones are more compressed. In this way an almost cup-shaped structure is created. The flower organs, six bloom cladding (tepals), six stamens (stamen) and three carpels (carpels) are formed regularly and most complete. The ovaries are always superordinate and end in three relatively long, papillary, often twisted scar branches . The capsule fruits are single-faced and three-seeded. The base of each seed is hairy. Many species have long white appendages ( elaiosomes ) at the tip of the seeds . In addition to the spread of wind ( anemochory ), the spread of ants ( myrmochory ) is predominant in the grove. The fatty appendages of the seeds serve as food for the ants. The seeds are carried into the ant burrows and transported to other places.
