Discussion | Glyceria pulchella grows in marshes, muskegs, ponds, and ditches, from central Alaska and the Northwest Territories to southern British Columbia and central Manitoba. In overall aspect, G. pulchella resembles G. striata and G. elata. It differs in having somewhat stiffer and straighter panicle branches, in addition to larger spikelets and florets.
