The buck goose foot ( Chenopodium hircinum ) is a species of plant in the foxtail family (Amaranthaceae). It originates from South America and is also found inconsistently in Central Europe.

description

The goosefoot is an annual herbaceous plant with a height of 20 to 100 cm. It is heavily floured and has an intense, unpleasant smell of spoiling fish. The alternate leaves are (at least initially) floured on both sides and matt. The blade of the lower leaves is clearly three-lobed with an almost rectangular central lobe and forward-facing side lobes that reach approximately to the middle of the length of the blade. The base of the spread narrows in a wedge shape. The leaf margin is more or less serrated.

The long-branched inflorescence has no bracts in the upper part. Inflorescence axes and the green inflorescence are powdered floury. The ripe fruit remains enclosed in the flower envelope. The horizontal, longitudinally flattened seed is shiny and blunt-edged. The seed coat is covered with honeycomb-like pits and radial grooves.

The flowering period extends from August to October.

Chromosome number

The number of chromosomes is 2n = 36.

Occurrence and endangerment

The buck goose foot is native to South America . Its populations are considered to be globally endangered. As an introduced species, it is also found in South Africa as well as in northwestern Europe , central Europe and parts of eastern Europe .

In Germany , the goosefoot is a neophyte that appears rarely and inconsistently in short-lived ruderal vegetation ( Chenopodietea societies), especially at transshipment points such as train stations or docks or on wool waste. It prefers dry, nutrient-rich, often raw gravel or sandy soils. The warmth-loving species is restricted to low-lying areas in southern and central Germany.
