Triglochin maritima

As long as the bottom is at least temporarily saturated with water and is saline to some degree, sea arrowgrass has no problem growing. That can mean high up as well as lower down in salt marshes and inland of the dike where there is seepage or remnants of salt still in the soil. Compared to its family member marsh arrowgrass, sea arrowgrass forms fuller clusters, is less delicate and its inconspicuous flowers are bunched close together along the stem. In addition, the foot of the stems and leaves grow slanted out of the ground. Sometimes, the plants in the middle of the cluster die so that the remaining plants seem to form a fairy ring, just like some mushrooms.

Somewhat sturdy erect perennial of brackish or saline wet habitats with short, stout rhizome; scapes 20-50 (—80) cm. long, stout, often somewhat curved above Leaves linear-subulate, thickish, about half as long as the scapes, 3-4 (—6) mm. wide, not furrowed, semiterete but slightly flattened towards the apex Racemes 20-40 cm. long, scarcely elongating in fruit. Flowers greenish, 2-3 mm. across; pedicel 1-2 mm. long, slightly elongating after flowering, shorter than the fruit, ascending. Perianth segments 2-2.5 mm. long, and nearly as broad, ovate—elliptic with somewhat rounded apex. Carpels (3—) 6, all fertile. Fruit 3-4 mm. long, 2 mm. broad, oblong-ovoid, with angular edges or hexagonal margin, not appressed to the axis; mericarps separating completely on dehiscence, slightly grooved on the back, roundish at the base, each 1-seeded; seed about as long as the carpel.

Inflorescences: scape often purple near base, mostly exceeding leaves, 1--16.5 cm  0.5--1 mm; racemes 6--45 cm  1.5--7 mm; pedicel 1--4  0.2--0.3 mm. Flowers: tepals elliptic, 1.3--1.7  0.6--1.4 mm, apex acute; pistils 6, all fertile.
