Annual, perennial herb, rhizomed or dense-tufted, terrestrial or aquatic.
Leaf: generally ± basal, alternate, ± flat to narrow- cylindric; sheath open, generally liguled.
Inflorescence: spike or generally ± scapose raceme; bracts 0.
Flower: generally bisexual; perianth parts generally 6 in 2 whorls (0, 1) [3, 4], free, ± green or tinged ± red-purple; stamens 0, 1, 3, or 6, filaments short, ± fused to perianth; pistil 1, carpels 1, 6 [3, 4], ± fused, separating in fruit [or not], each with 1 chamber and 1 ovule or 3 carpels fertile, 3 sterile, placentas basal, stigmas generally ± sessile.
Fruit: achene or generally mericarps.
3 genera, 30 species: temperate, circumboreal, Australia, s Africa, South America.

Plant ± glabrous.Key to Triglochin
Leaf: basal, ± tufted; sheath membranous; ligule tip entire to 2-lobed [0].
Flower: perianth parts generally adaxially concave; anthers ± sessile; stigma papillate or ± plumose.
Fruit: achene or generally 3, 6 mericarps.
Seed: 1, linear, ± flat or angled.
± 20 species: temperate, circumboreal, Australia, s Africa, South America. (Greek: 3 points, from fruits of some) TOXIC when fresh, from cyanogenic compounds.
Perennial 1–6 dm, loose-tufted to mat-forming; rhizomes often creeping, ± slender.
Leaf: 5–30 cm, generally 1–2 mm wide, ± round or semicircular in ×-section; ligule 0.5–1.5 mm, tip deep-2-lobed.
Inflorescence: aerial raceme, >= leaves; pedicels 3–7 mm in fruit, ascending.
Flower: perianth parts generally 6, 1–2 mm; stamens generally 6; fertile carpels 6.
Fruit: mericarps 6, 3–6(7) mm, fully separating, abaxially smooth or weak-ridged. Some authors merge Triglochin concinna, Triglochin maritima, but plants of n CCo very different in habit, stature, and grow together without intergrading. Some plants of interior may be more difficult to distinguish from Triglochin maritima, need study. [Online Interchange]
