Genus Triglochin
Arrowgrass Family (Juncaginaceae)

Arrowgrass growing near an irrigation pond

(Triglochin maritima)

This plant (not a true grass) grows in marshy places and moist meadows along with cattails and reeds.

The green plant can be very poisonous to livestock because it contains hydrocyanic acid. However the dried or roasted seeds are used by many animals (and have also been used by humans) as a food source.
