The dark lungwort ( Pulmonaria obscura ) is a plant species within the family of the predatory leaf family (Boraginaceae). It is widespread from northern to central Europe.
description
Vegetative characteristics
The dark lungwort is a perennial herbaceous plant and reaches stature heights of 10 to 20, sometimes up to 30 centimeters. The upright stem is covered in the upper part and on the branches of the inflorescence with strong bristles, stalk glands and soft hair ( indument ).
The leaves are more softly hairy, 4 to 6 inches long, 1 to 2 inches wide and only very rarely lightly spotted on the nerves. The basal summer leaves are divided into a 5 to 10 centimeter long petiole and leaf blade. Their simple leaf blade is 4 to 12 centimeters long and about twice as long as it is wide and heart-shaped, elongated with a pointed upper end.
Generative characteristics
The flowering period extends mainly from March to May. The flowers sit in coils with leaves on the base . The hermaphrodite flowers are five-fold with a double flower envelope. The corolla is 10 to 15 millimeters long, initially pink and later red-violet. The corolla tube is bare under the hair ring.
The nuts are 3.5 to 4 millimeters in length, are initially hairy, later bald and shiny brown to black in color.
The basic chromosome number is x = 7; it was diploidy , triploidy and tetraploidy with chromosome number 2n = 14, demonstrated 21 and 28th
Occurrence
Pulmonaria obscura occurs in southern Europe, in eastern, central and northern Europe, as well as in Turkey and western Siberia. It is a temperate continental floral element . It is the most common Pulmonaria species in Central Europe . The dark lungwort is very rare and endangered in Austria, while it is widespread in Switzerland.
The dark lungwort is widespread to scattered in Germany. In the north and in the foothills of the Alps it is rare or absent in parts.
The dark lungwort grows in mixed deciduous and coniferous forests. It thrives best on soaked, nutrient-rich, alkaline, but not always calcareous soils . It is a character species of the order Fagetalia in Central Europe .
Systematics
The genus Pulmonaria is extremely complex and difficult. There are numerous transitions and hybrid forms between the individual species. In some cases, the specific clans can only be determined by chromosome analysis. The dissemination information in the literature is therefore often incomplete or incorrect.
