Honeysuckle \Hon"ey*suc`kle\, n. [Cf. AS. hunis[=u]ge privet.
   See Honey, and Suck.] (Bot.)
   One of several species of flowering plants, much admired for
   their beauty, and some for their fragrance.
   [1913 Webster]

   Note: The honeysuckles are properly species of the genus
         Lonicera; as, Lonicera Caprifolium, and Lonicera
         Japonica, the commonly cultivated fragrant kinds;
         Lonicera Periclymenum, the fragrant woodbine of
         England; Lonicera grata, the American woodbine, and
         Lonicera sempervirens, the red-flowered trumpet
         honeysuckle. The European fly honeysuckle is Lonicera
         Xylosteum; the American, Lonicera ciliata. The
         American Pinxter flower (Azalea nudiflora) is often
         called honeysuckle, or false honeysuckle. The name
         Australian honeysuckle is applied to one or more
         trees of the genus Banksia. See French honeysuckle,
         under French.
