Arrowgrass is found in the Pacific coastal states, through the western and northern United States, and throughout Canada.  It is often found in thick patches, and its leaves at first appear to be those of a rush or grass.  The leaves of Triglochin maritima fill the picture at left.  Careful examination shows the yellow/green flowers with pink plumules.  When Arrowgrass is in flower, a quick tap on the stalk will produce a cloud of pollen.

Linnaeus named this genus in 1753 and also named this species but called it Triglochin maritimum.  Asa Gray renamed it Triglochin maritima in 1856.  "Triglochin" refers to the "three-pointed" fruit of some members of this genus.   "Maritima", "of the sea", refers to one very common location of this plant; it is often called "Seaside Arrowgrass".

The quite noticeable pink/purple feathering is probably a fringing of the stigma.
