Derivation of the botanical name:
Eriophorum from the Greek, erion, "wool", and forew (phoreo), "to bring or carry"; hence, "wool bearing",
vaginatum from the Latin vagina, "a covering, sheath", and atus, "possessive of or likeness of something"; hence, "sheathed".
  • The standard author abbreviation L. is used to indicate Carl Linnaeus (1707 – 1778), a Swedish botanist, physician, and zoologist, the father of modern taxonomy.
