The achenes are 3 to 5 millimeters long. The pappus is 4 to 5 millimeters long.

The number of chromosomes is 2n = 38.

Occurrence

The distribution area of Adenostyles alpina extends from Spain and France , Italy , Sicily , Germany and Switzerland to Slovenia and Croatia .

The Green Alpendost occurs on nitrogen-rich, alkaline-rich soils in mountain forests, in tall herbaceous areas and on the banks of streams. It is a Petasition-Paradoxi-Verband character type , but also occurs in high-montane Fagion or Piceion plant communities .

It can be found in the Alpine foothills and in the Alps at altitudes of 1200 to 2000 meters. In the Allgäu Alps, it rises in the Tyrolean part near the Kaufbeurer house near Hinterhornbach up to an altitude of 2010 meters.
