Saxifraga cuneifolia

Wedge Leaf Saxifrage ( Saxifraga cuneifolia )

The wedge - leaf saxifrage ( Saxifraga cuneifolia ), also called Keilblättriger saxifrage, is a native to the mountains of Europe species of the genus Saxifrage ( Saxifraga ).

Features

The wedge - leaf saxifrage is a perennial herbaceous plant ( Chamaephyt ) and reaches stature heights of 10 to 20 cm. It forms foothills with low leaves. The leaves are alternate in a basic leaf rosette. You do not have lime -secreting dimples, but a bright cartilage edge. They are weak fleshy to leathery. The basal leaves are ovate or roundish, and narrowing operates like a wedge into the bare petiole. The leaf blade is in the lower third of entire, previously mostly sawn or scored with two to six teeth. The end tooth is blunt, and often less than the lateral.

The loosely Rispige inflorescence is often fluffy studded with glandular hairs. The sepals are beaten down in the heyday. The petals are white, they have the most basic yellow dots. They are 2.5 to 4 mm long, and thereby 1.5 - 2.5 times as long as the sepals. Pollination is by insects. The flowering period extends from May to August.

The two-horned, vielsamige fruit capsule does not disintegrate to maturity.

The species has the Chromosomnenzahl 2n = 28

Dissemination and locations

The wedge - leaf saxifrage comes from Northwest Spain (Sierra Meirama ) over the Pyrenees and Cevennes and the Alps and the Northern Apennines to Croatia and Bosnia- Herzegovina before. Other deposits are found in the eastern and southern Carpathians. In Austria it is in the Southern Alps areas frequently, otherwise scattered to rare, and occurs in Carinthia, Salzburg, Tyrol, Vorarlberg and Tyrol. The occurring in Austria clan is the subspecies subsp. D. A. robusta Webb.

The wedge - leaf saxifrage grows in woods, on shaded rocks and boulders. It comes mainly in humid locations with humus-rich and calcium-poor soils in front of the montane to alpine altitude level.

System

A distinction can crop leaf saxifrage two subspecies:

• Saxifraga cuneifolia subsp. cuneifolia; it occurs only in France and Italy
• Saxifraga cuneifolia subsp. D. A. robusta Webb; it comes from the Pyrenees through the Alps to the former Yugoslavia and to the Carpathians before.
