The strip-lady's mantle ( Alchemilla lineata ), also Striped Frauenmantel called, is a plant from the genus lady's mantle ( Alchemilla ) within the family of Rosaceae (Rosaceae).

description

The striped lady's mantle grows as a deciduous, perennial herbaceous plant that reaches heights of 5 to 50 centimeters. The vegetative parts of the plant are closely covered with hair. The leaves are divided into a petiole and a leaf blade. The petiole is hairy close-fitting. The coarse leaf blades of the basal leaves are roundish and 9 to 13 lobed with a width of up to 15 centimeters. The leaf lobes are separated from one another by clear, wide V-shaped incisions. The upper side of the leaf is hairy only on the leaf teeth and the underside of the leaf at least adjacent to the leaf veins and basal lobes. The leaf teeth are 1 to 2 mm long, corresponding to 1.25 to 4% of the spreading radius. The living leaf blade is above with noticeably sunken adrenal nerves, below (more than above) often hairy everywhere (0 to 150 hairs on 1 cm²), the leaf blade is lobed to 3 to 30% of the radius.

The flowering period extends from June to October. The hermaphrodite flowers are yellowish green. Lonely nuts are formed.

The basic chromosome number is x = 8.

ecology

The striped lady's mantle is a hemicryptophyte .

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

Occurrence

The striped lady's mantle occurs almost in the entire Alpine region ( Switzerland , Austria , Germany , Italy , France ), furthermore in the French and Swiss Jura , also in the Pyrenees and Vosges ; in the northern foothills of the Alps , the striped lady's mantle is far from the edge of the Alps . In Germany it occurs very scattered to rarely in the Alps, scattered through the entire Bavarian Alps with a focus on the Allgäu Alps , and rarely in the southern Black Forest and is not considered endangered at its German sites.

The striped lady's mantle thrives in the montane to subalpine altitudes . It colonizes fresh meadows , fresh deciduous and coniferous trees , pastures and tall herbaceous areas .

Systematics

The first description of Alchemilla lineata was made in 1895 by Robert Buser in New memoranda of the General Swiss Society for the whole of science , Volume 34, page 131. A synonym for Alchemilla lineata Buser is Alchemilla vulgaris subsp. lineata (buser) chamois. Alchemilla lineata belongs to the Alchemilla section from the Alchemilla genus .
