description

Stems with single-veined leaves

Basket stand

Baskets: the bracts are too translucent towards the edge.

Open basket with fruits. The cardboard hairs are connected to one another at the bottom.

Achenes

The perennial plant is between 10 and 40 centimeters, exceptionally up to 80 centimeters high. It makes numerous, non-flowering, fresh green rosette leaves. The strong, upright, mostly unbranched stem is tomentose.

The basal leaves are lanceolate and short-stemmed, the numerous alternate, single-veined stem leaves linear and sessile. They are two to six centimeters long and three to four millimeters wide. Their underside is tomentose, the top is balding.

The flower heads form a spike-shaped entire inflorescence, which takes a third to five sixths of the stem length. They have a diameter of six to nine millimeters, a brownish to yellowish white color and each contain around seventy individual flowers. The five overgrown, mostly slashed bracts are predominantly dry-skinned and the majority have a noticeable dark spot. The seed is a yellow-brown, elongated nut whose pappus , which is covered with unbranched or only weakly branched short hairs, is slightly brownish or reddish.

Flowering time is from July to September.

The number of chromosomes is 2n = 56.

Similar species

The similar Norwegian Ruhr herb has a shorter flower spike, the central stem leaves are three-veined, the non-flowering rosette leaves are fewer and those on the inflorescence are obsolete.

Distribution and location

The forest Ruhr herb is native to Europe and is also found in East America. It often grows on forest paths, clearings, railroad lines, sand pits and grasslands. In the Alps it usually reaches an altitude of 1700 meters. In the Allgäu Alps in Bavaria on the Iseler , it rises to an altitude of 1860 meters. The light-loving, nitrogen-showing plant prefers lime-poor, moderately fresh clay soils. In Central Europe it is a species of the order Atropetalia.

ecology

The forest Ruhr herb is a nitrification indicator and a humus eater. There is self-pollination and insect pollination.

Taxonomy

The forest Ruhr herb was first described by Carl von Linné as Gnaphalium sylvaticum in Sp. Pl .: 85, 1753. Synonyms are Omalotheca sylvatica (L.) Sch. Gdp. & FW Schultz , Gnaphalium rectum Sm. And Gnaphalium sylvaticum subsp. carpetanum (Will.) Rivas Mart.

Medicinal and ornamental plant

The forest Ruhr herb was previously used against diarrhea, dysentery and respiratory problems. Today it is found in rock gardens as an ornamental plant.
