features
The hand-leaved lady's mantle is a thin, medium-sized plant similar to Alchemilla hoppeana . The leaf blades of the basal leaves are 2 to 8 centimeters wide and are kidney-shaped, usually seven-part, sometimes nine-part on large plants, 225 ° to 330 ° (360 °) and flat. 76 to 93 (100)% incision is made on the central leaflet. Otherwise they are more and more shallower towards the edge. The leaflets are fused up to 7 millimeters, two to five times as long as they are wide, lanceolate to wedge-oblong-obovate, rounded to pointed and 60 to 80% imperforate. The upper side of the leaves is dull and yellow-green to light grass-green, the underside thickly silky-white and silky. There are 6 to 15 teeth on the leaflets. These are 0.5 to 1.5 millimeters long (which corresponds to approximately 2 to 7, rarely up to 9% of the radius of the blade), 0.5 to 3 millimeters wide and have a length to width ratio of 0.5 to 2 on. They are pointed, usually clearly visible, and usually directed forward or slightly inclined. The end tooth is shorter. The petioles are neither reddened inside nor out. The partial inflorescences are crowded spherical. The flower stalks have a length of 1 to 3, rarely up to 7 millimeters. The flowers are 3 to 4 millimeters long, 3 to 5 millimeters wide and yellow-green. The sepals are 1 to 1.5 times as long as they are wide and horizontal to curved back. The stylus protrude only a little, usually 0.3 to 0.7 millimeters, rarely up to 1 millimeter.

The species was even found at an altitude of 2300 meters on the Gemmi Pass . It grows in crevices, on rubble and on stony alpine mats over lime, Nagelfluh and Molasse . It is mainly found in the subalpine level.
Alchemilla chirophylla together with Alchemilla alpigena in the Swiss Jura in the companies Potentillion caulescentis with viride Asplenium and Erinus alpinus , in Erico-Pinion with alpinum Laburnum , Erica herbacea , Rubus saxatilis and Libanotis pyrenaica and variae Seslerion with Herzblättrigen ball flower and Galium anisophyllon find . The species is also less common in the mesobromion .
