The awns-Meier ( Asperula aristata ) is a plant from the genus Meier ( Asperula ) within the family of the Rubiaceae (Rubiaceae). Their main distribution is in southern Europe and extends northward to Austria and Switzerland .

description

The Grannen-Meier grows as a perennial , herbaceous plant that can become lignified at the bottom and can reach heights of 10 to 60 centimeters.

The non-flowering plants are gray or gray-green in color. The more or less erect, ascending or prostrate-ascending stems are often short haired in the lower area and usually bald towards the upper regions. The leaves are often four in whorls . The simple leaf blade is usually 15 to 25 (10 to 40) millimeters long and only 0.5 to 2 millimeters wide and lanceolate to linear. The leaf blade is Spreitenquerschnitt not weak rewound or only partially down and has a central rib and a usually 0.1 to 0.2 millimeters long, hyaline blade tip.

The branched inflorescences with numerous, depending on the subspecies, pyramidal, umbrella-shaped, cephalic or more or less auricular partial inflorescences are free like the slightly lanceolate to broadly lanceolate-egg-shaped bracts . The flowers are either sitting or arranged on stalks up to 1.5 millimeters long. The hermaphrodite flower is fourfold. The corolla , which is somewhat funnel-shaped, has a corolla tube that is two to three (1.75 to 4) times longer than the corolla lobes that are not or clearly provided with appendages. The four petals are colored in greenish-violet, violet or yellowish to pink and reddish hues depending on the subspecies.

The partial fruits are warty and rarely hairy.

The number of chromosomes is 2n = 20 or 40.

Occurrence

The Grannen-Meier occurs mainly in the southern European, Mediterranean region on the Iberian Peninsula , the Balearic Islands , in France , Italy and the Balkan Peninsula . In the north, the distribution area extends to South Tyrol, Switzerland and south-eastern Austria. The Austrian occurrences are rare and are associated with the Asperula aristata subsp. oreophila reported from the state of Carinthia . The Grannen-Meier occurs in dry and steppe lawns on warm, dry, base-rich stone or gravel soils and is a species of the Festuco-Brometea class.

Systematics

The first publication of Asperula aristata was made in 1782 by Carl Linnaeus the Younger in Supplementum Plantarum Systematis Vegetabilium Editionis decimae tertiae, Generum Plantarum Editiones Sextae, et specierum Plantarum Editionis Secundae. Editum a Carolo a Linné. Brunsvigae [Braunschweig] Vol. 120 . As synonyms for Asperula aristata L.f. among others Asperula peristeriensis Halácsy and Asperula majoriflora Borbás are given.

Asperula aristata belongs to the section Cynanchicae DC. within the genus Asperula .

This polymorphic species is initially divided into five subspecies, the confirmation of which in the system, however, requires more detailed studies:

  • Asperula aristata L.f. subsp. aristata as a nominotypical taxon
  • Asperula aristata subsp. condensata ( hero ) honorable. & Krendl : With violet petals in western and central areas of the Balkan Peninsula
  • Asperula aristata subsp. nestia ( Rech.f. ) Honorable. & Krendl : With yellowish red petals in northern Greece and southern Bulgaria
  • Asperula aristata subsp. oreophila ( Briqu. ) Hayek : With pink petals in the southern Alps, the Apennines and the Pyrenees . According to R. Govaerts it is a synonym of Asperula aristata subsp. scabra .
  • Asperula aristata subsp. scabra ( J.Presl & C.Presl ) Nyman : With greenish-violet, light violet or yellowish petals in southern Europe and northwards to southern France and the north-west of the Balkan Peninsula
  • Asperula aristata subsp. thessala ( Boiss. & Heldr.) Hayek : With reddish petals in the mountains of Greece .
