Lactuca muralis
Mauerlattich ( Mycelis muralis )
The Mauerlattich ( Mycelis muralis ) is the only species of the monotypic genus Mycelis within the sunflower family ( Asteraceae).
Description
The Mauerlattich is a herbaceous plant. The leaves are lyre-shaped - fiederteilig. The leaflets are relatively angular. The terminal leaflets is substantially greater than the lateral leaflets.
The basket- shaped partial inflorescences are arranged in very loose paniculate inflorescences. The best way to recognize the Mauerlattich by its cup. These are pretty small - diameter of about 1 cm - and almost always consist of only five yellow ray florets that are trimmed front and provided with five teeth.
The black-brown achene is short beaked. The pappus consists of a series of long hair, which is surrounded by a series of short bristles.
Ecology
The Mauerlattich is a perennial Hemikryptophyt and a stem plant. With his injury occurs from milk juice.
The flowers are vormännliche "basket flowers from Cichorium type". Pollinators are bees relatives, flying, etc.
The fruits are achenes, which propagate as Schirmchenflieger and water Misty by the pappus; next there will be a spread by ants and spread by humans synanthropic.
The flowering period extends from July to August, the fruit ripening from August to October.
Occurrence
The Mauerlattich mainly grows in woods and thickets in the penumbra into the shadows. It prefers moderately rich soil. It is not uncommon, although its frequency varies greatly from area to area.
Originally its range Europe - in the east to the Caucasus in the north to Norway, in the south to North Africa. Meanwhile, he is also found in North America and New Zealand.
System
After gene sequence analyzes of Mauerlattich belongs to the close relationship of the genera lettuce (Lactuca ), Milchlattiche ( Cicerbita ) and Steptorhamphus. He will, therefore, as before, counted in more recent literature on the Lattichen and then carries the scientific name Lactuca muralis (L.) Gaertn. The basionym of Mauerlattichs under which it was first published in 1753 by Carolus Linnaeus in Species Plantarum, is Prenanthes muralis L.
