    • n triglochin A genus of monocotyledonous plants, formerly known as Juncago (Tournefort, 1700). It is the type of a group of 3 or 4 small genera of bog-plants, the Juncagineæ, by many long made a suborder of the order Alismaceæ, but now classed as a tribe of the order Naiadaceæ. The genus is characterized by bisexual bractless flowers with three to six carpels, each with one ovule. It includes 10 or 12 species, natives of salt-marshes and fresh-water bogs of the colder parts of both hemispheres. They are erect scape-bearing plants, usually from a tuberous root-stock, their roots sometimes also tuber-bearing. They produce elongated flat or somewhat cylindrical leaves, sometimes floating, and rather small greenish flowers in an erect spike or raceme. They are known as arrow-grass; two species occur in the northeastern United States.
