The long-limbed lady's mantle ( Alchemilla longinodis ) is a species from the genus of lady's mantle ( Alchemilla ).
features
The long-limbed lady's mantle is a weak, small to medium-sized plant. The leaf blades of the basal leaves have a width of 1.5 to 6 centimeters and are kidney to semicircular and 180 to 315 ° comprehensive. They are light blue-green to dark gray-green, dull, gray to silvery white on the underside, with a funnel-shaped stalk, but neither wavy nor wrinkled. They are divided into 7 to 9 sections on (40) 50 to 85% of the radius. The sections are obovate to oblong-linear, 1.5 to 3 times as long as wide, 33 to 60 ° wide, truncated or rounded and 7 to 13 teeth. The teeth are 0.5 to 2 millimeters long, which corresponds to 4 to 7% of the spreading radius, 0.5 to 2 millimeters wide, 0.5 to 1.5 times as long as wide, broadly crooked-triangular to oblong- wart-shaped, pointed and parallel to tapering. The end tooth is the only one that is dominated by its neighbors. The stem is 5 to 20 centimeters long, 1.5 to 2 times as long as the petioles and erect or short ascending. The upper internodes are long. The partial inflorescences have moved apart. The width of the largest stem leaves corresponds to 6 to 10% of the stem length. The stipules on the uppermost stem leaf are 5 to 7 millimeters long and 2 to 4 lobed. The flowers are 2 to 3 millimeters long, 3 to 4 millimeters wide and yellow-green to yellow. The sepals are 1.2 to 1.5 times as long as they are wide and 0.8 to 0.9 times as long as the sepals. At last they are erect and spreading.
Occurrence
The long-limbed lady's mantle is only known from the Lower Valais above Finhaut in the granital Alps of Salvan . The species can be found here especially in the Triege valley. It grows mainly in the subalpine level at altitudes of 1400 to 1800 meters. It was found on La Gueule at an altitude of 1960 meters. Their locations are mats, crevices, rubble , bushes and clear areas in the uppermost coniferous forest region. Alchemilla longinodis has similar requirements for location as Alchemilla pallens and is mainly to be found in humid, shady, sheltered places. It grows in fresh, stony, lime-free but mostly base-rich and only rarely weakly acidic, mostly fine-earth , moderately nutrient-rich, humus clay soils.
Alchemilla longinodis is mainly in the dressings Mesobromion (associated with grandiflora Prunella , Carlina acaulis , Carduus defloratus , Acinos alpinus , Trifolium pratense , Hieracium bifidum and 2 Thymus TYPES) Polygono-Trisetion , alpinae Poion and Nardion (here together with Alchemilla alpina ) to be found. In the contact area of these associations, the long-limbed lady's mantle achieves high consistency. Furthermore, gaps in Adenostylion alliarae societies (together with Alnus alnobetula , Astrantia minor , Ranunculus serpens ), in Rhododendro-Vaccinion and in Vaccinio-Piceion are used. It grows in crevices in the Androsacion vandellii together with Silene rupestris , Alchemilla saxatilis , Alchemilla alpina , Bupleurum stellatum , Cerastium arvense subsp. strictum , Gentiana purpurea and in Thlaspion rotundifolii- or Potentillion caulescentis societies together with Campanula cochlearifolia , Aster bellidiastrum , Valeriana tripteris and Cystopteris regia .
etymology
The name longinodis is derived from the Latin longus = long and nodum = knot. It may refer to the long internodes of the stem.
