1777, “the plant life of a region or epoch,” from Latin Flora, Roman goddess of flowers, from flos (genitive floris) “flower,” from *flo-s-, Italic suffixed form of PIE *bhle- “to blossom, flourish” (cf. Middle Irish blath, Welsh blawd “blossom, flower,” Old English blowan “to flower, bloom”), extended form of *bhel- (3) “to thrive, bloom,” possibly identical with *bhel- (2) “to blow, swell” (see bole). Used as the title of descriptive plant catalogues since 1640s, but popularized by Linnaeus in his 1745 study of Swedish plants, “Flora Suecica.”
