The Saxifraga Aizoides ( Saxifraga aizoides ) is a plant of the genus saxifrage ( Saxifraga ). It is also known as the brook saxifrage or spring saxifrage , which indicates its preference for a moist location. More rarely, this species is also called the lashed saxifrage . The Artepipheton aizoides (Greek = always living) refers to the evergreen leaves.
description
The sedum saxifrage is a richly branched, grass-growing, perennial plant and reaches heights of about 5 to 20 centimeters. It has loosely leafed, glandular-haired stems . The mostly dark green, often red overflowing leaves are 10 to 25 mm long and are quite fleshy, whereby the species in its vegetative state resembles the genus of sedum or stonecrop . The leaf margin is ciliate, at the leaf tip a lightly placed cartilage tip can be seen.
Two to twelve flowers stand together in a loose, glandular, hairy cluster . The hermaphrodite flowers are about 15 mm in diameter. The petals are yellow to dark orange, rarely they are also dark red, with darker points. The flowering period extends from June to September.
The sedum saxifrage has chromosome number 2n = 26.
ecology
The flowers of sedum-Streinbrechs be next Diptera also ants visited. The seeds remain buoyant for three weeks and thus explain the frequent descending of rivers to far below the actual distribution area.
Occurrence
The distribution area includes the arctic and sub-arctic Canada with southern extensions on the west and east coast to the USA border. Greenland , eastern Iceland , Svalbard , Novaya Zemlya , the polar Urals and arctic NE Russia with the Kola Peninsula , Scandinavia and the Alps from the Pyrenees to the Balkans . Pollen was found in late glacial sediments in Denmark, the Netherlands and some German low mountain ranges. The plant is also common in northern Ireland and Great Britain (south to Yorkshire ).
The sedum saxifrage prefers spring meadows, but also rubble ( glacial moraines ) and rock (damp) at altitudes between 600 and 3100 meters. In the Allgäu Alps, it rises on the north ridge of the Biberkopf in Bavaria up to 2300 meters above sea level. It occurs on ooze-wet, base-rich, mostly chalky, more or less humus-poor, pure or stony-gravelly clay or marl soil, but also on stone soil with little fine earth. It thrives in Central Europe in societies of the Cratoneurion commutati association, but also occurs in moist Thlaspietea rotundifolii societies or in the Caricion davallianae. In the Arctic , it is also common in the relatively dry tundra . It descends with the rivers far into the foreland (about to Munich with the Isar ). In Northern Europe it also grows at sea level .
The sedum saxifrage is considered endangered in Austria in the northern foothills of the Alps.
Historical
This species was known to the botanist Valerius Cordus as early as 1563 under the name Sedula montana pulchra . Linné found this typical arctic-alpine plant in Lapland and gave it its current name in 1753.
Common names
In Lower Austria and Tyrol, the locals also call the sedum saxifrage "chamois", as do many other plants that chamois like to eat. In some areas of Tyrol, the name " wart herb" is also used because it was used to remove warts .
