Description

The Hairy love grass grows as tufted spreading, procumbent, geniculate - ascending or erect, annual plant growth and reaches heights of 10 to 60 cm. The blade has two to three nodes ( more nodes ). The leaf blade is 3-15 cm long and 1-3 mm wide, its edge is without small bowl-shaped glands. The leaf sheaths are bald and wear only at its opening a tuft of hair. The leaf margins are sparse nodular kurzdrüsig. It is characterized by 1 to 2 mm long cilia on the leaf surface. The ligule ( ligule ) is designed as a ring of 0.3 to 1.5 mm long eyelash hairs.

The panicle is 4-16 cm long and 2-10 cm broad; it is loose, spread and contracted after flowering time. The lower panicle branches arise to third to sixth ( rarely two), they are thin, smooth and pliable and wear at the base of 3 to 4 mm long protruding hairs. Spikelets are 6 - to 15 - flowered, 4 to 8 mm long and from 1 to 1.5 mm wide. The glumes are rather uneven; lower glume is much shorter and narrower than the upper one. The lemmas 1.5 to 1.8 mm long.

The caryopsis is elliptical and 0.5 to 0.8 mm long.

Occurrence

The Hairy love grass originally came from the Mediterranean and the southern parts of Asia, but is now common in warm temperate and tropical regions around the world. In Europe, this species occurs from southern Europe, north only available up to middle Europe.

The Hairy love grass thrives in step societies in ways that railway embankments, in the pavement and in waste places on sunny, dry, low lime sand and gravel soils. In the Alps it only rises to altitudes of 1180 meters. In Germany, the Hairy love grass is naturalized in southwestern Baden- Württemberg, is also introduced in North Rhine -Westphalia, Saxony, Lower Saxony, Brandenburg and Mecklenburg -Vorpommern ago.
