The Dach-Pippau is a gray-green, deciduous, annual to perennial herbaceous plant that reaches heights of 10 to 60 centimeters. The more or less richly branched stem is downy hairy to bald. The lower leaves are pinnate. The upper and middle stem leaves are linear, seated with an arrow-shaped to heart-shaped base, curled down at the edge and have only a few saw teeth.

The flowering period extends from June to October. In total inflorescences there are many cup-shaped partial inflorescences. The gray-felted cup cover is bell-shaped at a height of 7 to 9 millimeters. The inner bracts are silky-haired on the inside. The flower heads have a diameter of 15 to 20 millimeters. The flower heads contain only ray florets. The ray-flowers are light yellow. The two-branched style are brownish-green.

The achenes are ten-ribbed and narrowed like a beak. The pappus is pure white.

The number of chromosomes is 2n = 8.

ecology

The Dach-Pippau is a hemicryptophyte or therophyte .

There is insect pollination or self-pollination. There is wind spread, Velcro spread or ants spread.

Occurrence

The Dach-Pippau is a Nordic-Eurasian (continental) -sub-Mediterranean floral element and has its main area in Eastern and Southeastern Europe and Asia. In northern, central and eastern Europe, its area extends to central France, eastern Spain and the Balkan Peninsula. In Asia you can find it in Siberia, Kazakhstan, Mongolia, China and in Far Eastern Asian Russia. In North America the species is a neophyte.

The Dach-Pippau needs nitrogen-rich, sandy-gravelly or stony soil . He loves warmth and populates walls, wasteland paths, more rarely fallow land and fields. It is a character species of the Sisymbrion association, but also occurs in societies of the order Polygono-Chenopodietalia. In the Allgäu Alps, it rises in the Tyrolean part below the valley station of the Jöchelspitze cable car up to 1100 m above sea level.

In Lower Austria and in the lowlands east of the Elbe it occurs in a scattered manner, to the west of it and in the sandy areas of the low mountain ranges it is rarely found, likewise in the canton of Valais , in the Lower Engadine and at the foot of the Alps.

Taxonomy

The first publication of Crepis tectorum was in 1753 by Carl von Linné in Species Plantarum , Volume 2, p. 807.
