RHO-DO-DEN'DRON, n. [Gr. ῥοδοω, a rose, and δενδρον, a tree.]

The name of a genus of plants, and the type of the natural order Rhododendraceæ. Four species are known to grow in New England, viz. two deciduous leafed, which are called upright or swamp-honeysuckles; and two evergreen ones, which can hardly be said to have any distinctive popular names. Several of the species of this genus are medicinal, and many of them are highly ornamental.
