The bald lady's mantle ( Alchemilla glabra ) is one of the rose family (Rosaceae). It belongs to the Alchemilla glabra group, which is characterized by at least partially close-fitting hairs. The sepals and the outer sepals are unequal in size and shorter than the sepal cup.

Appearance

The bald lady's mantle is a medium to large species that can reach a height of up to 60 cm. The basal sheets are kidney to circular and have an open, narrow to wide basal bay. This is often somewhat funnel-shaped and 6 to 15 cm wide. The blade is 1/4 to 1/3 wide and divided into 7 to 9, sometimes up to 11, and obtuse-triangular, hyperbolic lobes. The lobes have 6 to 10 narrow to broad triangular teeth, some of which are inclined towards the tip of the lobe. The top and bottom of the leaf is completely bare. Only the veins in the outer half are covered with hair. The leaf stalks are usually only hairy on the lower part, rarely the hairiness extends over the entire length.

The flower stalks are also usually only hairy on the lower part, about 1/3 of the stem. Otherwise they are bald. The flowers are yellowish-green in color and grow in shingled to tufted partial inflorescences . The flower cup has a length of about 1.5 mm and is conical-bell-shaped. The sepals are relatively pointed ovoid-triangular and up to 1.6 mm long. The outer sepals are usually narrower than half the width of the sepals.

The bald lady's mantle mainly blooms in the months of May to August.

The number of chromosomes is 2n = 96 or 102-110.

Distribution and location requirements

The bald lady's mantle is widespread in Europe. In the north up to the 70th parallel, its distribution area extends in the south to Spain, Italy and the Balkan Peninsula. To the east it penetrates as far as Latvia and Lithuania.

In Germany, Austria and Switzerland, Alchemilla glabra is one of the most common species. It is represented almost in the entire area.

The bald lady's mantle grows mainly in poor mowing and litter meadows, on the edges of ditches and on forest paths. It prefers base-rich, fresh to moist locations.

Possible confusion

Alchemilla glabra can be easily distinguished from other Alchemilla species due to its almost lack of hair, although it is very variable in the shape of the leaves and the extent of the hair .
