Big Knorpellattich ( Chondrilla juncea )

The Knorpellattiche ( Chondrilla ), also called cartilage salads, form a genus in the subfamily Cichorioideae within the daisy family (Asteraceae).

Description

Appearance and leaves

Chondrilla species are perennial herbaceous plants that reach heights of growth between 40 and 150 cm. They form taproots. Each plant can consist of one to six branched stems that are hairy bristly at the base and smooth the top.

The leaves are borne in basal rosettes and are also distributed on the stem. The petioles are winged. The leaf blade of basal leaves is sinuate to pinnatifid. The stem leaves are smaller and easier.

Inflorescences, flowers and fruits

The terminal and lateral bloom conditions are usually individually or too few. The flower heads have a diameter of 2.5 to 5 mm. It is a series of five to nine equally protean bracts present. In a flower heads are only seven to fifteen hermaphrodite, fertile, zygomorphe ray florets together. The early wilting corollas are yellow.

The light brown to black, almost cylindrical achenes possess more than five ribs are clearly beaked and covered with protuberances and appendages. The Pappus consists of a series of 40 to 50 white, smooth bristles.

Ecology

There are hemicryptophytes.

Some species reproduce apomictically or optional continued apomictically.

Systematics and distribution

The genus Chondrilla was erected in 1753 by Carl Linnaeus in Species Plantarum, 2, pp. 796-797. The name was Chondrilla of Dioscorides for plant species used the milky sap ( latex) included. Therefore Linné used this name for the genus Chondrilla.

Chondrilla species occur naturally in Eurasia. In North America, the Great Knorpellattich ( Chondrilla juncea ) is considered an invasive plant. In Germany, only the two types Alps Knorpellattich occur ( Chondrilla chondrilloides ) and Big Knorpellattich ( Chondrilla juncea ).
