description

Five-fold flowers
Aremony ( Aremonia agrimonoides )

The aremony grows as a deciduous, perennial herbaceous plant and reaches stature heights of mostly 5 to 40, rarely up to 180 centimeters. The arching, rising stem , mostly reddish at the bottom, is only covered in the upper area with long outer hairs and numerous glandular hairs, which means that the plant smells partly aromatic.

The leaves are in a basal rosette and there are one to three bract-like leaves on the stem. The basal leaves are 10 to 15 centimeters long and pinnate interrupted with two to four pairs of downwardly smaller, oval, coarsely toothed partial leaves and smaller up to 5 millimeters long, mostly whole-margined intermediate leaflets. The stem leaves are usually three-part. The feathery leaves are (at mid-rise height) 10 to 30 centimeters long and have five to nine, rarely up to 13 major and six to ten smaller, unterseits green to gray-green, never weißfilzige pinna leaflets with six to 14 rough, sharp teeth pairs.

The flowering period extends from May to June. Three to five flowers are grouped together in dense racemose inflorescences . The hermaphrodite flowers are radially symmetrical and five-fold. The five free, yellow petals are oval with a length of 3 to 4 millimeters and often slightly edged. There are two, enclosed by calyx cup, ovary present.

The fruit contains one, rarely two seeds. The ripe fruit is enclosed by the hard inner calyx, which towers above the hard outer calyx. The ripe fruit is only half furrowed and has outer bristles that are bent back.

The chromosome number is 2n = 42.

ecology

In Aremonia agrimonoides is a hemicryptophytes .

Occurrence and endangerment

The aremony is an east sub-Mediterranean floral element . The distribution area extends from southern and central Europe , southwest Germany and Sicily eastwards to Asia Minor . Their main area of distribution is in southern and southeastern Europe. In Central Europe it occurs rarely at the southern foot of the Alps , but locally in populations with a large number of individuals; it is found sporadically near Planegg in Bavaria and on the Upper Rhine near Dangstetten and Basel .

In Central Europe it settles in open areas in mixed deciduous forests, especially on paths and on the edges of forests. The aremony needs somewhat moist, at least calcareous , if not calcareous, clay soils with a strong mixture of humus or a pronounced mulch layer . In Central Europe it occurs in Saum societies (Alliarion) of the Carpinion association. In Southeastern Europe it is a species of the order Quercetalia pubescentis.

It is entered in the 1996 Red List of Endangered Plant Species in Germany in category 3 = endangered.
