The large, broadly egg-shaped, glabrous, bluish leaves on the underside are dentate; the upper leaves have a heart-shaped or spear-shaped and pointed auricle that surrounds the stem.

The ( pappus ) is dirty-yellowish-white, brittle and fragile.
The number of chromosomes is 2n = 12.
ecology
The pollination is done by bees and flies. The diaspores spread through the wind.
Occurrence
The Swamp-Pippau belongs to the Nordic-Eurasian-sub-oceanic floral elements . It occurs in Central, Eastern and Northern Europe and the British Isles, as well as in Turkey and western Siberia. In Germany it is widespread and only rare in warm and dry regions. In the Alps, it thrives at altitudes of 1920 meters. In the Allgäu Alps, it rises in Vorarlberg between Unterkrumbach and Haldenwanger Eck to an altitude of 1780 meters.
The Crepis paludosa is a half light plant of wet meadows and moors , the breaking and riparian forests and the Hochstaudenfluren and bushes. It thrives on wet, nutrient-rich and humus-rich clay soils . It is a Calthion association character in Central Europe.
