description

The leathery lady's mantle is a deciduous, perennial herbaceous plant that reaches heights of 5 to 50 centimeters. The stems are usually completely bare, only rarely are individual stems hairy on the lowest one to three internodes ( indument ). The petioles are almost semi-cylindrical. The leathery, coarse, basal leaves are round and nine or eleven-lobed with a width of up to 15 centimeters. The leaf lobes are flat-arched to briefly parabolic and the leaf margin has egg-shaped to rounded blunt teeth. The upper side of the leaf is usually bare with a sunken leaf vein network . The leaf veins on the underside of the leaf are only hairy on the upper end ( trichomes ). The stem leaves are large up to the inflorescence and have wide blunt leaf lobes.

The flowering period extends from June to October. The flowers are hermaphroditic. The outer sepals are 0.33 to 0.8 times as long as the sepals .

The basic chromosome number is x = 8.

ecology

The inclined lady 's mantle is a hemicryptophyte and a half-rosette plant.

The flowers are proterandric . From an ecological point of view, these are disc flowers with open nectar and fly flowers with exposed honey. The typical pollinators are flies .

The inclining lady 's mantle is autonomously obligatory apomictic ; No pollination is necessary for seed development . Diaspores are the nuts.

Occurrence

The leathery lady's mantle thrives in the mountains of western , southern and central Europe . Its distribution area extends from Spain and Andorra to Tyrol and Salzburg ; north of the Alps you can find it in the Swiss Jura , in the Black Forest and in the Alpine foothills near the edge of the Alps .

The leather lady's mantle occurs in Austria , France (including the Vosges ), Switzerland (including the Jura), Germany (very scattered in the Alps, rare in the Alpine foothills, rare in the Black Forest); whether there are deposits in the Italian Dolomites is not certain. In the Red List for Germany it is classified as not endangered, in Baden-Württemberg it is considered endangered with an unclear status and in Bavaria it is rated as very rare and highly endangered. In Bavaria the main occurrence is in the Allgäu Alps and in the Tannheimer Mountains , it is also rare in the western and central Alpine foothills; In 1991 there was a new find in the Ammer Mountains .

The calcareous leather lady's mantle thrives in the submontane to subalpine altitudes . It colonizes spring meadows , brook edges, (fresh) damp to trickling wet, short-grassed or gappy meadows and pastures . The leathery lady's mantle thrives in the plant societies ( plant sociological units according to Oberdorfer ) of the Montio-Cardaminetea class (spring corridor societies) and Stellario nemorum-Geranietea sylvatici class (alpine-montane tall perennial and riding grass societies).

The pointer values ​​according to Ellenberg are: light number L7 = half-light plant, temperature number T3 = cool pointer, continental number K 3 = showing sea to moderate maritime climate, humidity number F9 = wetness pointer, humidity change: showing no change in humidity, reaction number R4 = acid to moderate acidity, nitrogen number N3 = Indicates low nitrogen, salt number S0 = does not bear salt, heavy metal resistance: not heavy metal resistant.
