Etymology

borrowed from New Latin Phlox, a genus name, going back to Latin phlog-, phlox "a flame-colored flower," borrowed from Greek phlóx, genitive phlogós "flame, flash (of lightning), blaze, radiance, inflammation, a flame-colored flower," o-grade derivative from the stem of phlégein "to burn up, blaze, gleam" — more at phlegm
