The karbolähnlich smelling milky juice are all plant parts, especially the root , an unpleasant odor. All parts of the plant above ground are hairy. The leaves are serrated to wide-indented, the blade of the lower leaves is narrowed into the petiole while the upper leaves sit on the stem with a hollowed base .
Generative characteristics
The flowering time in Central Europe extends from June to mid- October . In a total inflorescence there are usually several to many basket-shaped partial inflorescences, which nod when budding. The flower heads have a diameter of 30 to 35 millimeters. The shell usually has no or only a few glandular hairs. The outer bracts are 1 to 1.5 millimeters wide and reach up to 2/3 the length of the inner ones . The bottom of the basket is hairy.
In the flower baskets there are only yellow ray florets with yellow styles . While the inner achenes are 10 to 13 millimeters long and have a long, almost hair-shaped beak , the outer achenes are only 5 to 7 millimeters long and have a shorter and stronger beak. The pappus is pure white.
The number of chromosomes is 2n = 10.
ecology
The poppy poppy stink Pippau is a therophyte to hemicryptophyte .
Occurrence and endangerment
The poppy-stink pippau is native to Central , Eastern and Southeastern Europe , France , Western Asia , the Caucasus and Turkmenistan . In the German-speaking area, the poppy-stink pippau is indigenous only in Austria , in Germany it appears as a new citizen , in Switzerland it is only inconsistent .
In Austria the poppy stink pippau occurs frequently in the Pannonian region , otherwise only rarely on moderately dry ruderal areas such as earth cracks, gravel pits, roadsides, loading areas and railway gravel in the colline altitude . The permanent occurrences are limited to the federal states of Vienna , Lower Austria and Burgenland , the inconsistent ones to Upper Austria , Styria , Carinthia and Salzburg . In Tyrol , the unstable occurrences of the past have become extinct again, in the northern and southeastern Alpine foothills the poppy stink Pippau is endangered.
The poppy-stink Pippau loves chalk .
