EPILOBIUM, the WILLOW-HERB; a genus of the monogynia order, belonging to the oestandria class of plants. There are seven species, all of them natives of Britain. They grow in marshes, or under hedges in moist and shady places; having blossoms generally of a red colour, and sometimes of considerable beauty. The most remarkable is the hirsutum, commonly called codlins and cream. The top-shoots of this plant have a very delicate fragrancy; but so transitory, that before they have been gathered five minutes, it is no longer perceptible. Horses, sheep, and goats eat this plant; cows are not fond of it; swine refuse it.
