Arrow, Pod or Goose Grass (Triglochin spp.).
This plant grows at most elevations throughout North America, preferring wet alkaline soils. It flourishes in marshy ground and irrigated pastures, often growing in native meadows cut for hay. It is a perennial grass-like plant with fleshy, half-rounded, dark green leaves clumped at the base of the plant. Leaves are 5 to 7 inches (12 to 18 cm) long, linear, unjointed, and sheathed at the base. The inflorescence is a pedicled raceme from 1.6 to 5 ft (0.5–1.5 m) in length that appears as an unbranched, unjoined flower spike. The flowers are inconspicuous and numerous, with a greenish, six-parted perianth. The fruits are made up of three- to six-celled capsules that turn a golden brown before splitting.
