description

Illustration with details

The whorled millet is annual and reaches heights of 10 to 100 centimeters. Your stalks are upright or kinky ascending. The ligula forms a ring of hair. The leaves are 4 to 25 cm long and 5 to 21 mm wide.

The inflorescence is contracted to a cylindrical, dense panicle , which is interrupted at most in the lower part. The bristles are 3 to 7 mm long, their spiky hairs are directed backwards, so the inflorescence looks like a burdock. This is a good indicator of the typical variety of this species. The spikelet is elongated-elliptical and 2 to 2.2 mm long. Its upper glume is as long as the spikelet and five-nerved, the lower glume is only 1/3 as long as the spikelet. The lemma of the upper, hermaphrodite flower is thickened with cartilage and, between the slightly protruding keels, slightly wrinkled with narrow, folded side surfaces.

The flowering period extends from June to September.

The number of chromosomes is 2n = 36.

Occurrence

The whorled millet occurs in southern and central Europe as far as the Middle East and North Africa . Their home is the tropics and subtropics of the Old World . But it is a neophyte worldwide.

The whorled millet grows in gardens, in root crop fields and in vineyards in dry and warm locations on nutrient-rich and well-fertilized sandy-loamy soils. It is a nitrogen pointer and a heat pointer. It mainly thrives in lower altitudes and only rises in the southern Alps to altitudes of over 1200 meters. It is a species of character of the order Polygono-Chenopodietalia.

variability

Closely related to the whorled millet is a clan that is viewed as a separate species, the deceptive millet or short-bristle millet ( Setaria verticilliformis Dumort. , Syn. Setaria ambigua (Guss.) Guss. Non Mérat , Setaria gussonei Kerguélen ). It can be distinguished by its less dense inflorescence, in which the main axis between the spikelets is visible in the lower part and in which the inflorescence does not look like a burdock because the bristle hairs are directed forward and not backward. Her bristles are only 3 mm long. However, this clan is only presented as a variety ( Setaria verticillata var. Ambigua ( Guss. ) Parl. ) To the whorled millet by other authors .
