Taxonomy

The Geneva Günsel was first published in 1753 by Carl Linnaeus in Species Plantarum. The epithet " genevensis " goes back to Johann ileocecal (1541-1612), who had the kind described in Historia Plantarum in 1651 as Consolida media Genevensis and illustrated. He had the plant at Geneva (Latin: Geneva ) collected and observed.

Location

The Geneva Bugle is a species of dry grasslands and semi-arid grassland. In climatically favored regions it is also found along forest edges. He is a Rohbodenpionier and often comes in halbruderalen societies Erdanrissen, embankments or Wegrainen ago. It prefers sites with limestone bedrock.

Ecology

The four surrounded by the calyx nutlets are each provided with an oil body and are carried off by ants. However, the nature multiplies vegetatively by root sprouts. The coat reduces the solar radiation and evaporation.
