oleraceus, of the vegetable garden; herbs used in cooking.
Hieracium, Greek hierax, "a hawk." Pliny the Elder (23-79) believed that hawks fed on this plant to strengthen their eyesight and thus it became the Greek and Latin name for this and similar plants, the common name of which is hawkweed.
Lactuca, Latin lact, milk, referring to the milky sap.
  • The standard author abbreviation L. is used to indicate Carl Linnaeus (1707 – 1778), a Swedish botanist, physician, and zoologist, the father of modern taxonomy.
