Derivation of the botanical name:
Ranunculus from Latin rana, "little frog," because many species tend to grow in moist places.
acris, acer, sharp, irritating, pungent.
  • The standard author abbreviation L. is used to indicate Carl Linnaeus (1707 – 1778), a Swedish botanist, physician, and zoologist, the father of modern taxonomy.
  • The standard author abbreviation auct. is used to indicate the Latin term 'auctorum', meaning "of authors", often given to indicate that a name is used in the sense of a number of subsequent authors and not in its (different) sense as established by the original author.
  • The standard author abbreviation Beck is used to indicate Günther von Mannagetta and Lërchenau Beck (1856 – 1931), an Austrian botanist.
Owing to its acrid properties Ranunculus acris is usually avoided by cattle.
