The Elbe love grass or Elbe love grass ( Eragrostis albensis ) is a species of the sweet grass family (Poaceae). This small grass grows in Central Europe in flushing fringe associations ( river reporting corridors ) of streams.
description
The Elbe love grass grows in small nests as a spread to upright, annual plant with heights of 10 to 60 (rarely 110) cm. The leaf sheaths are glandless. The upper ones are bare. Shaggy, longer hairs are developed at the vaginal mouths of the lower leaf sheaths.
The spikelets of the panicle are four- to seven-flowered, the panicle axis is rough. At the lower end of the panicle there are only one or a maximum of two panicle branches.
The number of chromosomes is 2n = 40.
Distribution and location requirements
The Elbe love grass thrives on the banks of the Elbe in river reporting corridors on parts of the river bank that dry out when the water levels are low in summer . Larger populations are often developed on the flat sandy beaches of the Upper and Middle Elbe . The species grows scattered in the Hessian and Rhineland-Palatinate Rhine Valley.
Systematics
The Elb love grass was described by Hildemar Scholz in 1995 in the negotiations of the Botanical Association of Berlin and Brandenburg 128.74. However, the systematic rank is disputed. The Elbe love grass has only been observed since the beginning of the 1990s, whereby the mass populations on the Elbe were initially noticed. It is assumed that the Elbe love grass emerged in Central Europe from a species that was introduced from the east and related to the hairy love grass ( Eragrostis pilosa ).
