Vegetative characteristics

The folded windrow is a perennial herbaceous plant . The prostrate or flooding stalks are 10 to 70 centimeters long, crawl and take root at the nodes. The nodes are bare.

The alternate arranged on the stalk leaves are divided into leaf sheath and blade. The ligule is 2 to 6 millimeters long, a membranous edge rounded at the top. The leaf sheaths are closed up to the top and compressed laterally. The leaf blade is 5 to 30 inches long and 5 to 10 millimeters wide.

Generative characteristics

The flowering period extends from June to August. The paniculate inflorescence is slender, 10 to 30, rarely up to 45 centimeters long, often interrupted and more or less all-round. the mostly three to five lower side branches are off the main axis. The longest side branch is up to 12 centimeters long and carries 5 to 15 spikelets, the others are shorter and carry only 1 to 5 spikelets. The light green spikelets are slender and spindle-shaped with a length of about 10, rarely up to 25 millimeters and a width of 1.5 to 2 millimeters and contain seven to twelve flowers. The lower glume is 1.5 to 2.5 millimeters in length shorter than the upper, which is 2.5 to 4 millimeters long. The lemmas are 3.5 to 4.5 millimeters long, blunt, wavy trimmed or indistinctly tridentate, with seven strong nerves and without awn. The palea are two-veined, slightly notched at the top. The anthers are often yellow and 1 to 1.5 millimeters long.

The number of chromosomes is 2n = 40.

Occurrence

The folded plume occurs from Europe to northwestern China and Pakistan. There are also occurrences in northwestern Africa in Morocco, Algeria and Tunisia. The folded plume rises in the Alps to an altitude of about 2000 meters.

The folded plume thrives in the reed beds of streams and ditches in mostly slowly flowing waters on very nutrient-rich and base-rich, often calcareous , humus-rich mud soils . He loves light and warmth. Glyceria notata is a character species of Glycerietum plicatae from the Glycerio-Sparganion association, but also occurs in plant communities of the Bidention association.

Taxonomy

The first description of Glyceria notata was in 1827 by François Fulgis Chevallier in Flore des Environs de Paris , Volume 2, page 174. In older Floren it is usually referred to as Glyceria plicata (Fr.) Fr. , like Fries in Novitiarum Florae Suecicae Mantissa , Volume 3, 1843, page 176 she published as Art; the basionym for this is Glyceria fluitans var. plicata E.M. Fries in Novitiarum Florae Suecicae Mantissa , Volume 2, 1839, page 6. Other synonyms for Glyceria notata Chevall. are: Glyceria fluitans var. plicata (Fr.) Griseb. , Glyceria acutiuscula H.Scholz , Glyceria turcomanica Kom. , Panicularia plicata (Fr.) Druce . The specific epithet plicata means "folded" and the specific epithet notata means "drawn".
