Roof Pippau ( Crepis tectorum )

The Pippau ( Crepis ) are a genus of flowering plants in the sunflower family ( Asteraceae). The genus includes about 200 species. They have a wide distribution in North America, Eurasia and Africa. The word means crepis shoe sole ( shape of the leaves ). Pippau comes from the Slavic (Polish pepewa ) and was related to the dandelion (Taraxacum officinale).

Description

The Pippau species are one-, two-year or perennial herbaceous plants, reaching heights of growth from 3 to 120 cm depending on the type. The simple or branched stems are erect to creeping. They usually form taproots, sometimes they form rhizomes. The most stalked leaves are often together in undergraduate rosettes. The petioles are more or less winged. The leaf blades are simple, lobed to pinnately lobed. The leaf margins may be smooth, toothed or serrated.

The upright bloom conditions are sometimes singly or usually in branched inflorescences total. The flower heads have a diameter of 4 to 15 mm. The 8 to 18 bracts are in one to two rows; their edges may be green to yellowish and are often hairy. The inflorescence base is flat or convex. The flower heads contain only five to over one hundred florets. The color of ray florets is usually yellow or orange, sometimes white, pink or reddish.

The often curved achenes are yellow, brown, green, red or black with ten to twenty ribs. The pappus consists of 80 to 150 whitish, flexible, non- feathered bristles, which are more or less the same or the outer shorter; they may be in one or two rows.
