description

Inflorescence of the goat's rue ( Galega officinalis )

Galega styles are upright, much branched perennial herbaceous plants . The leaves are pinnate unpaired , the pinna are entire. The (lateral) leaf veins facing away from the midrib are protruding and reach all the way to the leaf margin. The stipules are deeply cut into two to five very narrow lobes. The outer stipple (away from the petiole) points straight down.

The narrowly branched panicle inflorescences are axillary or terminal. Pre-leaves are missing.

The zygomorphic flowers are classic butterfly flowers . The calyx is bell-shaped with five uneven teeth. The crown is white to purple. The flag is inverted egg-shaped to rounded and hairless. The nail, the pointed basal end of the flag, is short. The wings are a little shorter than the flag and are basal, close to the shuttle. The shuttle is as long as the wings.

The stamens are fused along the entire length of the stamens . The only carpel is on top with many ovules . The stylus is bent with a terminal scar .

The linear, flattened legumes have a chamber, are not indented at any end and have parallel strong ribs on the surface.

distribution

Natural distribution area of ​​the genus Galega , red is the manifold center , the northern and western borders are uncertain, since stocks of Galega officinalis there may not be of natural origin

The distribution area of the genus Galega is the eastern Mediterranean, southern Central Europe, southern and eastern Europe and Asia Minor . The center of diversity, i.e. the area with the greatest biodiversity , is located in Asia Minor between the Black and Caspian Seas .

In addition to the Eurasian distribution area, there is a second natural distribution area in Africa, in the states of Ethiopia, Somalia, Kenya, Sudan and Uganda. The three species Galega battiscombei , Galega lindblomii and Galega somalensis can be found here , which are also grouped together in the Afrogalega section .

Galega officinalis and Galega orientalis are regularly grown as fodder crops. They could run wild, which led to a large number of neophytic occurrences. So there is Galega officinalis in Germany and Switzerland. In the United States, the species was first introduced in Utah and was able to spread from there. There are also imported stocks in Argentina, Chile, Ecuador and New Zealand. The species multiply quickly and uncontrollably and are considered invasive . In the USA, at least Galega officinalis was included in the “ Federal Noxious Weed Act of 1974 ”, which aims to curb the further spread.

species

Five species of the genus Galega are recognized as valid. These are:

  • Galega battiscombei (Baker f.) JBGillett : It only occurs in Kenya.
  • Galega lindblomii (Harms) JBGillett : It occurs in Kenya and Uganda.
  • Goat's Rue ( Galega officinalis L ): It is widespread in Eurasia and Africa and is worldwide, e.g. B. in the New World a neophyte .
  • Galega orientalis Lam. : Its home is Asia, but it is also found in Europe as a neophyte.
  • Galega somalensis (Taub. Ex Harms) JBGillett : Your home is only Ethiopia .
