The plant is slender and has numerous, acute-angled, relatively short branches. The leaves are two- to three-fold pinnate and have three- to five-part terminal leaflets . The " tip " is blunt or has a short spiked tip .

The double-gold inflorescences are relatively small. The numerous bracts (four to eight) are upright. The flowers are white-yellow. The fruit is elliptical with a length of 3.5 to 5 mm and a width of 2 to 3.5 mm. The edge ribs are about half as wide as the " fruit casing ".

It blooms in August and September.

The chromosome number of the species is 2n = 22.

distribution

General distribution

Peucedanum alsaticum (herbarium evidence of the stem leaf). Because of its rarity and endangerment, this species should not be collected under any circumstances!

The Alsatian hair strand occurs in Europe, from France and Northern Italy, Central Europe to the Balkan Peninsula; east to central and southern Russia and further to the Altai. It is a sub-Mediterranean-weak-continental floral element . It occurs in France, Germany, the Czech Republic, Austria, Poland, Slovakia, Hungary, Ukraine, Belarus, Moldova, European Russia, Romania, Bulgaria, Serbia, Slovenia, Croatia, Bosnia-Herzegovina, Montenegro, Albania, Kazakhstan, im western Siberia and the Caucasus.

Distribution in Austria

In Austria the species occurs frequently in the Pannonian area , rarely in the rest of the area, in the colline to submontane altitude range . The occurrences are limited to the federal states of Vienna , Burgenland and Lower Austria .

Distribution in Germany

Peucedanum alsaticum is very rare in Germany and only occurs in the central Rhine and Main area. In addition, it can only be found in a few places. It can still be found quite often in the ravines of the communities Alsheim and Guntersblum in Rheinhessen.

Location requirements

Peucedanum alsaticum grows in loose " herds " or individually in bright, sunny, dry places in a warm climate, on lime-rich, alkaline, mostly skeletal , "raw" soils . Peucedanum alsaticum prefers perennial communities, often on “slightly ruderal slopes” and in older fallow vineyards. Very often only a few plants bloom at the individual sites. In Central Europe it is a character species of the Geranion sanguinei association, but also occurs in associations of the Potentillo-Quercion petraeae or Convolvulo-Agropyrion associations.

Species protection
