description

Vegetative characteristics

The rust-red head is a hibernating green, rosette-free, perennial herbaceous plant that reaches heights of 15 to 30 centimeters. The lower leaf sheaths are dark red-brown.

Generative characteristics

The approximately 1 centimeter long inflorescence contains two to five short-stalked spikelets . The bract is as long as the inflorescence or it only slightly towers above it. The husks are dark red-brown. There are six perigone bristles , which are only slightly longer than the fruit.

The flowering time is at the end of full spring in May and June.

The number of chromosomes is 2n = 76.

ecology

The rust-red head is a helomorphic hemicryptophyte . The pollination is carried by the wind. The diaspores spread by the wind or by Velcro spreading and self-spreading.

Occurrence

The rust-red Kopfried occurs in Europe southwards to the Alps and to the Balkan Peninsula ; northward in Scandinavia to 66 ° north latitude. It used to be found in Scotland too.

In Central Europe, it predominantly populates flat bogs and swelling slopes as well as the dry edge of raised bogs. In the Swiss and German foothills of the Alps it occurs scattered, and there are often quite extensive populations there; otherwise it is very rare in Central Europe, and there it is absent in large areas. It rises in the Alps to altitudes of 1500 meters. In the Allgäu Alps it rises in the Tyrolean part near Reutte in Dürnau against the Vordere Mutte up to 1300 m above sea level.

In Germany, the rust-red Kopfried occurs in southern Bavaria widespread in the Alpine foothills and the upper plateau and scattered in the lower plateau and the Alps, in southeast Baden-Württemberg scattered in the Alpine foothills, in the eastern foothills of the Black Forest ( Baar and Jura ) and in northern Thuringia Haßleben and in eastern Mecklenburg-Western Pomerania are rare. In Saxony, Saxony-Anhalt and Brandenburg, the rust red head is extinct. The population is declining in Germany.

The habitat of the baseniferous plant are damp to seeping springs and fens. The rust-red Kopfried thrives best on very moist, weakly acidic or moderately calcareous soils , which should not be too low in bases. It is a character species of the Primulo-Schoenetum from the association Caricion davallianae.
