Dianthus seguieri
Bush carnation (Dianthus seguieri )
The Busch- carnation (Dianthus seguieri ) is a plant of the genus carnations (Dianthus ) within the carnation family ( Caryophyllaceae ). The distribution is almost confined Europe.
Description
The Busch- carnation grows as overwintering green, perennial herbaceous plant, reaching heights of growth from 10 to, usually 25 to 60 centimeters. The creeping to ascending and unbranched stems are divided into seven to twelve internodes. The leaves are arranged opposite constantly on the stem. The leaf sheath is 3-5 mm long. The simple leaf blade is narrow linear- lanceolate with a length of 30 to 60 mm and a width of 1 to 5 mm.
The flowering period extends from June to September. The flowers are borne singly or a few at a paniculate inflorescence that can be pulled together and head shaped. There are usually four (two to six) egg-shaped calyx scales available with borstlicher tip that are less than half as long as the calyx tube ( Dianthus seguieri subsp. Gautieri and Dianthus seguieri subsp. Glaber ) or about as long as those calyx tube ( Dianthus seguieri subsp. seguieri ). The calyx tube is cylindrical with a length of 14 to 20 mm. The plate of the petals is usually 10 to 14 mm ( 7-17 mm) long, wedge-shaped, serrated front, light to dark and with no drawing or a tuck deep purple points or at the base with white dots.
Occurrence
The Busch- carnation occurs in the low mountain ranges of western and central Europe. The distribution area extends from Spain, northern Italy and France to Switzerland, Germany and the Czech Republic as well as the Turkish province of Kars. In Austria it only occurs in Vorarlberg, where it was rediscovered.
The Busch- carnation thrives on poor grassland, forest and shrub borders, even in bright chestnut woods or on little fertilized meadows moderately fresh, lime-poor loam or sandy loam soils. It is light -loving.
System
The first publication of Dianthus seguieri took place in 1786 by Dominique Villars in Histoire des Plantes de Dauphiné, 1, p 330 The epithet seguieri honors the French botanist Jean -François Séguier.
From Dianthus seguieri there are at least three subspecies:
- Séguier Busch carnation (Dianthus seguieri Vill subsp seguieri, Syn: .. Dianthus seguieri subsp italicus Tutin. ): Its leaves are 1-2 mm wide, but the lateral nerves are much less clear than the median nerve. It occurs especially in the Southern Alps, in south-eastern France, Switzerland and northern Italy. Their chromosome number is 2n = 90
- Gautier -Busch carnation (Dianthus seguieri subsp gautieri ( Sennen ) Tutin, Syn. Dianthus gautieri Sennen, Dianthus neglectus Loisel. ): Its leaves are 1-2 mm wide and the lateral nerves are just as clear as the median nerve. The Hüllschuppen the cup is about half as long as the calyx. It occurs only in Andorra and in the eastern Pyrenees of Spain and France.
- Kahle bush carnation (Dianthus seguieri subsp glaber Čelak, Syn: .. Dianthus sylvaticus Hoppe ex Willd. ). This subspecies has 2-5 mm wide leaves. It occurs in France, Germany, Austria and the Czech Republic. Their chromosome number is 2n = 60
Conservation
Like all native to Germany cloves species this species is protected in Germany by the Federal Species Protection Ordinance. Since Dianthus seguieri but in Europe probably is rare everywhere, it is important to investigate their exposure closer to contribute to their protection. This happened, for example, Dianthus seguieri subsp. glaber by a work at the Bavarian State Office for Environmental Protection. < / ref >
