Triglochin concinna and T. maritima are frequently considered the same species; the treatment in Flora of North America synonymizes T. concinna with T. maritima (Haynes and Hellquist 2000). Both species produce a cyanide-containing sugar called triglochinin, which can poison livestock when eaten in large amounts. Production is highest in the spring (Majak et al. 1980), and because the compound remains potent in a dried state, care should be taken to prevent inclusion of young Triglochin in hay bales.
