Stechende Binse ( German )

provided by wikipedia DE

Die Stechende Binse (Juncus acutus) ist eine halophytische Pflanzenart aus der Familie der Binsengewächse (Juncaceae).

Beschreibung

Die Stechende Binse ist eine ausdauernde Pflanze, die Wuchshöhen von 30 bis 150 cm erreicht. Die Pflanze bildet große, dichte Horste mit steifen und stechenden, stielrunden Blättern. Die blühenden Triebe sind 2 bis 4 mm dick und werden häufig vom untersten, stark stechenden, stängelartigen Tragblatt überragt.

Der vielblütige Blütenstand ist meistens dicht und kugelig. Die 6 Blütenhüllblätter, mit breitem, häutigem Rand, sind etwa gleich lang. Die drei inneren Blütenhüllblätter sind breiter und haben an der Spitze ein häutiges Öhrchen. Blütezeit ist von April bis Juli. Die eiförmige Kapsel ist mit 4 bis 6 mm Größe etwa doppelt so lang die die Blütenhülle. Die Kapsel ist kurz bespitzt.

Die Chromosomenzahl beträgt 2n = 48.[1]

Vorkommen

Die Stechende Binse ist an den Küsten des gesamten Mittelmeerraums, des Atlantiks (nördlich bis Irland), des Schwarzen und Kaspischen Meeres sowie der Kanarischen Inseln verbreitet. Darüber hinaus findet sie sich in den Tropen und Subtropen der ganzen Welt.[2] Als Standort werden Sandstrände und Salzsümpfe bevorzugt. Seltener findet sich die Stechende Binse im Binnenland.

Systematik

Man kann zwei Unterarten unterscheiden:

  • Juncus acutus subsp. acutus: Sie kommt in den Tropen und Subtropen vor.[2]
  • Juncus acutus subsp. leopoldii (Parl.) Snogerup: Sie kommt im westlichen Mittelmeergebiet, in Makaronesien, im südlichen Afrika, von den südlichen Vereinigten Staaten bis ins nördliche Mexiko, vom südlichen Brasilien bis in die gemäßigten Zonen Südamerikas, auf den Bermudas und auf Ascension vor.[2]

Juncus acutus

provided by wikipedia EN

Juncus acutus, the spiny rush, sharp rush or sharp-pointed rush, is a flowering plant in the monocot family Juncaceae. It is native to the Americas, Northern and Southern Africa, Western and Southern Europe and West Asia, and is found in a variety of wet habitats, such as bogs, fens, meadows, and salt marshes,[2] and along the edges of ponds and lakes.[3][4]

The sharp-pointed rush is a perennial plant that grows to a height of about 60 to 100 centimeters (24 to 39 inches). It has slender, cylindrical stems with narrow, pointed leaves and clusters of small, light brown flowers that bloom in the summer.

This species is important for a variety of reasons. It provides habitat and food for a range of wetland animals, including insects, birds, and mammals. It is also an important component of wetland ecosystems, helping to prevent soil erosion and maintain water quality. In some countries like Australia it is considered to be an invasive weed[5] and the spines harmful to young children.[6]

In addition, sharp-pointed rush has been used for a variety of purposes, including as a source of fiber for making paper, baskets, and other woven products, and for medicinal purposes. The plant has also been used for landscaping and erosion control,[7] as well as for ornamental purposes in gardens and wildflower meadows.

Despite its ecological and cultural significance, Juncus acutus is considered to be of least concern in terms of conservation, as it is widely distributed and not currently threatened by habitat loss or other factors. However, continued conservation efforts are necessary to protect this species and its habitat and ensure its long-term survival.

Synonyms

  • Juncus acutus ssp. leopoldii (Parl.) Snog. -- Leopold's rush[8]
  • Juncus acutus L. var. sphaerocarpus Engelm[9]
  • Juncus acutus L. subsp. acutus
  • Juncus spinosus Forssk[10]
  • Juncus acutus ssp. leopoldii also known as Leopold's rush is a native of Arizona, California, Georgia and Nevada.[1][9]
  • Juncus acutus L. var. conglobatus Trautv
  • Juncus acutus L. var. decompositus Guss
  • Juncus acutus L. var. longibracteatus Buchenau[11]

Description

Juncus acutus is a brown and green[12] tussock-forming[6] perennial that can grow to 1.5 metres (4.9 ft)[12] tall in all kinds of soils,[13] in areas which go from extremes in flood and dry like dunes[4] or that just stay wet like lowland grassland and grassy woodland, riparian vegetation, freshwater wetland, and saline and subsaline wetlands.[14]

Stems and leaves
Pith filled stems and leaves arise from the base at different angles giving the plant a globe shape. The leaves form a basal sheath around the flower stem leaves and end with a stiff sharp point.[6]
Flowers
The flower stems are 2 millimetres (0.079 in) to 4 millimetres (0.16 in) in diameter and 4 centimetres (1.6 in) to 13 centimetres (5.1 in) long and are similar to the leaves. They emerge from the base at all angles and each have 1 - 6 flowers. Each flower has 6 stamens and 4 centimetres (1.6 in) to 25 centimetres (9.8 in) long bracts that terminate in a stiff and sharp point.[6] The flowers are hermaphrodite and are pollinated by the wind.[13]
Fruits and reproduction
Fruits are oval 3-celled brown capsules 4 millimetres (0.16 in) to 6 millimetres (0.24 in). The 1.2 millimetres (0.047 in) to 2 millimetres (0.079 in) long brown seeds have a tail at each end.[6]
Roots
Short[6] and robust rhizomes.[12]

Gallery

Distribution

Found principally in low-lying damp, low fertility areas[14] like sandy sea shores and dune slacks and coastal flats,[14] occasionally in salt marshes[13] and disturbed saline areas, mine dumps, lowland grassland and grassy woodland, riparian vegetation, freshwater wetland, and saline and subsaline wetlands[14]

Community species

In a natural shallow depression in the Murray River floodplain in South Australia:

Chemistry

The dimeric phenanthrenoid 8,8'-bidehydrojuncusol and the monomeric juncusol[15] and dehydrojuncusol can be isolated from J. acutus.[16]

L'espèce est évaluée comme non préoccupante aux échelons mondial, européen et français[2]. En France l'espèce a disparu (RE) en Haute-Normandie ; elle est considérée vulnérable (VU) en Pays de la Loire.

Description

C'est une plante vivace brun vert qui peut atteindre 1,5 mètre de haut.

Tiges et feuilles

Les tiges et les feuilles partent de la base à des angles différents donnant à la plante un aspect globuleux. Les feuilles engainent les tiges florales et se terminent par une pointe aiguë rigide. Leurs piqûres peuvent être douloureuses.

Fleurs

Les tiges florales font de 2 à 4 millimètres de diamètre et 4 à 13 cm de long et émergent de la base de la plante. Elles ont chacune de 1 à 6 fleurs. Chaque fleur a 6 étamines et de longues bractées de 4 à 25 centimètres de long qui se terminent par une pointe rigide. Les fleurs sont hermaphrodites et sont pollinisées par le vent.

provided by wikipedia IT

Il giunco spinoso (Juncus acutus L.) è una pianta della famiglia delle Giuncacee.[1]

Descrizione

È una pianta cespugliosa perenne di colore verde scuro che forma cespugli alti fino a 1,5-2,0 m.

Le foglie ed il fusto sono di forma cilindrica e pungenti, caratteristica che ha dato il nome a questa specie.

L'infiorescenza è composta da fiori bruni o rossicci, di piccole dimensioni.

Il frutto è una capsula trigona od ovale, di colore bruno rossastro.

Il periodo di fioritura va da aprile a luglio.

Distribuzione e habitat

È una pianta diffusa in tutta l'area mediterranea, rinvenibile anche in Sudafrica, California e America del Sud.[1]

È molto comune in Italia, ove predilige le zone umide delle regioni costiere; talvolta è presente anche a quote più elevate.

Il suo habitat ideale è rappresentato dalle zone umide ad alto tasso di salinità, da cui tuttavia può diffondersi anche alle aree circostanti.

Ситник острый (лат. Juncus acutus) — типовой вид рода Ситник.

Ареал

Ареал — район Средиземноморья, Кавказ, Иран, Британские острова. В Америке встречается в Северной Мексике и юго-западе США. Предпочитает увлажнённые места с засолением, но растёт и на пресноводных водно-болотных угодьях[1]. Вид занесён на юг Бразилии и в долину реки Муррей в Австралии.

Описание вида

Ситник острый — многолетнее травянистое растение высотой до 1,5 м. Листья жёсткие, с открытыми незамкнутыми влагалищами. Цветки 2-4 мм в диаметре, буровато-зелёные, быстро отцветают, опыляются ветром. Плодкоробочка.[2]

В Европе вид считается полезным растением, защищающим почвы от эрозии.[3] В Австралии, наоборот, ситник острый считается сорняком.[4]
