Plants of Triglochin gaspensis tend to form lawnlike patches in contrast to the clumped habit of other northern species of the genus.

Plants with strands of old leaves at base, (5--)10--15(--20) cm. Leaves curving outward from sheath at 30--50° angle, slender, almost terete, equaling or slightly longer than scapes, (5--)10--15(--20) cm; sheath 12.5--21  1.8----3 mm, ligule often hoodlike, apically 2-lobed; blade 0.5--1 mm wide, apex acute. Inflorescences: scapes often purple near base, (5--)10--15(--20) cm  0.5--1(--1.5) mm; thick; racemes (2--)3--5(--7) cm; pedicels 1.4--4  0.1 mm. Flowers: tepals somewhat rounded, 1.2--1.5  1.1--1.8 mm, apex obtuse; pistils (3--)6--(9--12), 6 fertile. Fruits: fruiting receptacle without wings; schizocarps linear, 3--4  1 mm; mericarps linear, weakly ridged, 3--4  1 mm, beak recurved, 0.9--1 mm. 2n = 96.

Triglochin gaspensis (common name - Gaspé Peninsula arrow grass) is a species of flowering plant in the family Juncaginaceae, native to eastern Canada (New Brunswick, Newfoundland island, Nova Scotia, Prince Edward Island and Quebec), and Maine in the north-eastern United States, where it is found growing in the tidal zone of the Atlantic coast below the high-water mark. It was first described by Helmut Lieth and Doris Löve in 1961.
