description

Vegetative characteristics

Fruit cluster

The real stone seed is an herbaceous plant and reaches heights of 30 to 100 centimeters. An upright, short, multi-headed, woody rhizome is formed. Its stems are grouped together, are stiff, branchy, round and rough. The leaves are lanceolate, sessile, lacks the base at the time of flowering, 5 to 10 centimeters long, 1 to 2 centimeters wide, entire, coarse.

Generative characteristics

The flowers are in double coils . The flowers are greenish-yellowish-white, 4 to 5 mm long, 3 to 5 mm wide. The partial fruits are 3 to 4 mm long, smooth, shiny, white, with a few dimples.

The number of chromosomes is 2n = 28.

ecology

The real stone seed is a hemicryptophyte . The weakly feminine flowers are pollinated by insects or self-pollinating .

The spherical mustard seed-sized partial fruits are similar to small stones and are rich in silica and carbonate. The partial fruits are mainly transported by running water.

Occurrence

The real stone seed is widespread in the northern hemisphere in Europe , Western Asia , in the Caucasus, in Pakistan, Nepal, Bhutan and India, in Central Asia , Siberia, in Mongolia, in China and in North America . In Europe it is becoming increasingly rare north of the Elbe and Vistula . The northernmost European occurrences are in Norway at 70 ° north latitude. In the southern hemisphere it is a neophyte and rarely occurs there.

The real stone seed is scattered as a river valley plant in thinned oak-elm floodplain forests, on forest paths and in bushes. It prefers fresh, nutrient-rich and calcareous loam and clay soils. In Central Europe, the plant is a character species of the order of the perennial borders on woody plants (Origanetalia vulgaris), but also occurs in societies of the Berberidion association or in the Querco-Ulmetum of the Alno-Ulmion association.

Locations and distribution in Central Europe

The real stone seed needs muddy and calcareous, loose loam or clay soil.

It inhabits light, warm, but not too dry deciduous forests and forest fringes. It is a character species of the dry forest fringes (Origanetalia vulgaris) in Central Europe.

In Central Europe it occurs only occasionally in the lowlands east of the Elbe; in the low mountain ranges with limestone only in mild locations; in the Jura and in the foothills of the Alps it is almost extinct, in the Alps it only occurs in warm valleys. In the Allgäu Alps, it rises in the Vorarlberg part at the foot of the precipices on the Gopfberg to an altitude of 1180 meters.

Toxicity

The plant parts are hardly poisonous.

Parts of the plant that contain active substances are the seeds. Active ingredients are octatetraenoic acid, lithospermic acid, pyrrolizidine alkaloids.

use

According to the doctrine of signatures , the real stone seed was used against stone ailments. It should also help against rheumatism .

In ancient China in particular , the roots were used to dye wool and silk . The naphthoquinone dye shikonin contained in it provides violet and purple hues.
