description

Appearance and leaf

The Turin-Meier grows as a perennial herbaceous plant with stature heights of (rarely 10 to) usually 20 to 50 centimeters. It forms a "rootstock-like" stem axis system with orange-colored and more or less horizontal, subterranean runners . The density of hairs ( trichomes ) on different parts of the plant can vary considerably depending on the area of ​​distribution. The strong, upright and clearly square stems are more or less clearly hairy.

The leaves are arranged in four whorls on the stem. The simple leaf blade is 3 to 6 centimeters long and 1 to 2.5 centimeters wide and lanceolate to egg-shaped, tapers abruptly towards the base of the blade and has a cartilaginous leaf tip. It is lighter in color from the base of the leaf, has three longitudinal veins and a clearly reticulated leaf vein and is hairy on the leaf veins and on the leaf edge.

Inflorescence and flower

The flowers are in dense, cephalic inflorescences , which are surrounded by long ciliate bracts and a whorl of four, leaf-like, broadly lanceolate to egg-shaped bracts . The hermaphroditic flowers are radial symmetry and four-fold. The chalice is reduced. The four white or pale yellowish colored, 10 to 14 millimeter long petals are fused tubular to narrow funnel-shaped. The crown consists of the 6.5 to 10.5 millimeter long corolla tube and the four corolla lobes that are 2 to 3.5 millimeters longer than they are wide. The stamens have stamens two to three millimeters long and 1.3 to 1.5 millimeters long, elongated anthers protruding above the corolla.

Two carpels are one under constant, egg-shaped, two-chambered ovary fused, with one ovule per ovary chamber. The 1 to 3 millimeters large and egg-shaped fruits have a smooth surface.

Chromosome number

The number of chromosomes is 2n = 22.

Occurrence and endangerment

The Turin-Meier is particularly widespread in southern Europe including the Balkan Peninsula and in southern Central Europe with south-eastern France, Switzerland , the Principality of Liechtenstein , in Austria in the westernmost state of Vorarlberg and eastwards via Hungary , Croatia and Romania . More resources are on the eastern peninsula of Crimea and the Near East regions of the Transcaucasus and in Turkey and Iran described. The occurrences in Germany , Denmark and Great Britain are based on neophytes .

In Central Europe, deciduous deciduous forests are settled , especially beech forests and bushes of the planar-colline to montane elevation . In Central Europe it occurs particularly in societies of the Tilio-Acerion or Carpinion associations.

The Turin-Meier is considered potentially endangered in Central Europe.
