Juncaginaceae is the botanical name of a family of flowering plants. For the past few decades such a family has been recognized by most taxonomists. They are also known as the Arrowgrass family.

The APG II system, of 2003 (unchanged from the APG system, of 1998), also recognizes such a family and places it in the order Alismatales, in the clade monocots. The family includes perhaps four genera (with Triglochin the best known), totalling about a dozen species, which are found in cold or temperate regions in both the Northern and Southern Hemisphere.

Description

Sea Arrowgrass Triglochin martimum

They are Marsh or aquatic herbs with linear, sheathing basal leaves.

The flowers are small and green in erect spikes or [[racemes}}. The flower parts come in threes, but the carpels are either 3 or 6, joined to a superior ovary.

The fruit is a capsule.^[1]

Example arrowgrasses Triglochin include Marsh Arrowgrass Triglochin palustre, Sea Arrowgrass Triglochin maritimum, Triglochin trichophora, Triglochin striata, Triglochin mucronata.
