The Stumpfblütige rush ( Juncus subnodulosus, Syn: .. Juncus obtusiflorus Ehrh ex Hoffm ), also called nodules bulrush, a plant of the family of Rushes is ( Juncaceae ).

Description

The overwintering green bulrush is a perennial, with long processes forming loose grass herbaceous plant with vigorous rootstock. It reaches heights of growth between 40 and 130 centimeters. The stems grow upright. Sterile shoots bear at the end of a stalk- like leaf, flowering shoots two nearly round in cross section, quergekammerte and 2 to 4 millimeters thick leaves. The ears of the leaf sheaths are brownish, short and rather coarse.

The inflorescence is a very bright when young, highly branched, loose Spirre with 10 to 50, sometimes 100 part inflorescences with right or obtuse projecting, rarely recurved branches. The second or higher order branches are conspicuous sparrig stand-off. The partial inflorescences reach about 5 millimeters long and are five to zwölfblütig. The up to 3 millimeters long tepals of the individual flowers are pale green to straw colored and elliptical in shape. You are obtuse rounded, hence the German name. The fruit capsule is slightly longer than the bracts, triangular - ovate and laterally compressed. She wears a short top. The seeds are reddish brown and reticulate patterned.

The flowering period extends from June to July.

Distribution and location

The Stumpfblütige rush is widespread in Europe, except Scandinavia, North Africa and parts of Asia Minor. Neophyte resources exist in New Zealand and the east coast of North America.

It grows in wet meadows ( Calthion palustris Tüxen 1937), intermediate marsh meadows ( Caricion davallianae Klika 1934) as well as in ditches on sickernassen, well-ventilated, more or less nutrient-rich, mostly lime - often saline, swamp humus or humic Kalktuffböden.
