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.
