HOUND, a dog; now used only of dogs of the chase, and especially of fox-hounds. Other breeds have a defining word pre fixed; e.g., boar-hound, stag-hound, etc. (See Doc.) (Cynoglossum), a widely distributed genus of the family Boraginaceae, including several species native to Great Britain and North America. The common hound's-tongue or gypsy flower (C. officinale), a native of Europe and Asia and found in waste grounds in the British Isles, is widely naturalized as a weed in eastern North America. It is an erect biennial, I ft. to 3 ft. high, with large, oblong, pointed leaves, purplish-red flowers, 4 in. across, and a conspicuous burlike fruit, which splits into four prickly nutlets. The wild comfrey (C. virginianum) or dog-bur, native to woods in the south-eastern United States, is a similar but slenderer plant with blue flowers. The western hound's-tongue (C. grande), also with blue flowers, grows in woods from California northward to Washington. (See BORAGI NACEAE and FLOWER.)
