description

The yellow meadow rue is a perennial herbaceous plant that reaches heights of (60 to) 70 to 110 (to 200) cm. There are always subterranean branches . The stems are bare and slightly angular to runny. The composite leaves are double to triple pinnate. The green, at most slightly frosted leaflets are predominantly three or five lobed or fissured. The lower leaflets usually have small, membranous accessory leaflets (stipella).

Stems and leaves
inflorescence

It blooms from June to August. Many fragrant flowers stand together in a panicle inflorescence that has a narrow, elongated outline. The 2.3 to 3.1 mm long nuts have six longitudinal ribs.

The number of chromosomes is 2n = 84; the species is dodecaploid.

ecology

The yellow meadow rue is a hemicryptophyte and a creeping pioneer plant. Its floral scent indicates that it is pollinated not only by the wind , but also by insects (pollen flower). The fruits are solitary nuts and they spread as wing fliers and swimming fruits .

ingredients

The roots contain the yellow-colored alkaloid berberine and other basic substances and are suitable for dyeing of wool .

Occurrence

The distribution area of ​​this often confused river valley plant extends from Ireland , western France and the Basque Country in the west to the catchment area of ​​the Ob on the other side of the Urals. At the northern border the distribution ends at the beginning of the Arctic climatic zone, in the south the closed distribution area extends to the Rhone and Danube floodplains ; south of it there are only very sporadic occurrences. Specified occurrences from Siberia could not be confirmed.

The yellow meadow rue prefers moist, nutrient-poor soils such as on ditches and fens. Since the meadows are more heavily fertilized today, it is no longer to be found that often. According to Ellenberg , it is a semi-light plant, intermediate-continental growing and an association character of the meadowsweet riverbank meadows (Filipendulion ulmariae), but also occurs in societies of the associations Molinion or Senecion fluviatilis.

Systematics

The yellow meadow rue was first published in 1753 by Carl von Linné in Species Plantarum . An important synonym is Thalictrum morisonii C.C. Gmel. Taxa that used to be considered subspecies of Thalictrum flavum are now changed to Thalictrum simplex subsp. simplex (Syn. Thalictrum flavum subsp. costae (Timb.-Lagr. ex Debeaux) Rouy & Foucaud ), and to Thalictrum speciosissimum L. (Syn. Thalictrum flavum subsp. glaucum (Desf.) Batt. ).
