Alchemilla sect. Plicatae is one of the 13 European sections of the genus Lady 's mantle ( Alchemilla ). Most of the species were earlier in the species groups Alchemilla vulgaris agg. and Alchemilla hybrida agg. guided.

This section consists of hybrids between the sections Ultravulgares , Alpinae and Pentaphylleae . Their characteristics are composed of the characteristics of the parent sections.

features

The representatives of the section Plicatae are mostly small to medium-sized perennials that are densely silky, woolly or velvety hairy. Species that are strongly influenced by the Ultravulgares section are quite large. The main axis usually has a diameter of less than seven millimeters and usually does not get older than five years. The first stems in the summer flowering sequence are regularly transformed into monopodial renewal shoots.

The primary leaf is often five-lobed and deeply divided. The spread of the basal leaves are usually deeply stalked and have few and coarse teeth. The petiole usually has a diameter of around one millimeter. At the top it has a groove, the vascular bundles are collateral. The stipules are quite long-lived, on a rosette there are up to six leaves with fresh stipules. The auricles of the stipules are free and have a distance of one millimeter from each other. The stipules have a green tip and one to seven teeth, the terminal tooth is usually much larger. The incision in the tute can be quite deep and is no more than 10 millimeters or 30% of the total length.

The stems are ascending to upright and usually up to 20 centimeters long. In some species it can reach 60 centimeters. A stem is four to ten limbed. It is hairy all along its length and is rarely bald. On the lowest stem leaf, the stipules are mostly to the side and are often spreading or sickle-shaped. On the uppermost stem leaf, a stipple has three to seven (rarely two to ten) teeth that are two to three times as long as they are wide.

The inflorescence consists of spherical monochasia whorls and is reminiscent of the parent section Alpinae . In many species it consists of only a few flowers . The individual monochasias are often shamrock. The flowers are yellow-green to green, the terminal flower is often five-fold. The flowers often nod when they are in fruit. The goblet is hairy, spherical to pear-shaped and slightly incised at the top. The sepals are about as long as the sepals, hairy and 0.8 to twice as long as they are wide. The outer sepals are shorter than the sepals, medium to very small, or even absent. The stamens are a maximum of 0.2 millimeters wide and at most a little broadened directly at the base. The disc is circular and has a wide bulge. The presence of two instead of the usual one fruit sheet is not rare. The scar is hemispherical or head-shaped, rarely hooked. The nuts are spherical, hairless, in most cases with short bills, and hardly protrude from the goblet.

The species of the Ultravulgares section are similar in their rhythm of life .

distribution

The species of the section Plicatae occur mainly in the mountains of Europe, with the exception of the south and the dry areas. In addition in the Middle East, in Siberia to Central Asia, in Mongolia and in Japan. In the north, the area extends to northern Scandinavia, northern Russia, the Faroe and Shetland Islands, Iceland, Greenland, Labrador and Newfoundland.

The plants usually grow on shallow, stony or rocky soils and in alpine meadows. They also occur in meadows. A few species are hygrophilous and grow in spring meadows and snow floors.

Systematics

The assignment of the species to the section follows Fröhner (1995), whereby changes to the section assignment and new species from Fischer (2008) have been adopted:
