Isoëtes maritima is a spore-producing herb in the Isoetaceae. It is native to Alaska, British Columbia, and Washington State.[1][2]
The epithet "maritima" and the common name "maritime quillwort" are misnomers. "Maritime" means "of the sea or ocean;" I. maritima occurs in fresh-water lakes and streams. It is similar to I. echinospora Durieu but with blunt spines and crests on the megaspores. I. echinospora has sharp, thin spines. Most of the other species in the genus have no megasporal spines.[1]
