Genus: Alchemilla
English name: Alpine lady's mantle
Zone: Mediterranean
Description
It occurs on grasses, camephytic and cervunal bushes, rock fissures. It grows in siliceous or limestone substrate, when the soil has a thick layer of humus or is decalcified, 1300-3100m.

Botanical Description
This is a subshrub of small or rarely medium size, creeping. The fertile stems are 3-20cm, 1-3 times the length of the petioles of the rosette leaves, erect to slightly ascending, completely covered with sericeous and applied hairs.
The rosette leaves are with the blade 1-4cm wide, reniform to semicircular, quite tender, palmate, flat, narrowly lanceolate to oblong-obovate, with the apex rounded or acute, not narrowed at the base like a petiole, and overlapping or tangent, in the middle, or divaricate lobes 30-60º wide, 2-9mm wide, slightly serrated and with an entire margin along 70-95% of its length. There are 5-11 teeth of the intermediate lobe, 0.5-2 x 0.3-3mm, broadly triangular-arched to sickle-shaped or linear, with an acute apex, directed towards each other or slightly divergent, with the upper surface of a yellowish green to meadow green, very bright when alive, and the underside of a white silvery, rarely silvery gray, generally very densely sericeous. The upper cauline leaf is with stipules of 3-7mm.
The inflorescence is with 15-300 flowers, from wide to narrow. It has partial spherical inflorescences, 5-10mm in diameter, very close to each other and sometimes coming together. The internodes are very short. The floriferous pedicels are 0.5-2mm (in terminal flowers, 0.5-3mm) with bracts on all flowers. The flowers are 2-4 x 2.5-4mm, yellowish-green to yellow. The stamens are with filaments of 0.3-0.7mm. There is 1 carpel. The style exceeds the nectar disk by 0.3-1.2mm. The stigma is 1/2-2/3 spherical, asymmetrical.
The achene is 1.2-1.6mm, acute to subobtuse, shortly rostrate, exceeding the disc by 20-33% of its length, glabrous or with groups of hairs at the base.
