|discussion=<p><i>Glyceria striata</i> grows in bogs, along lakes and streams, and in other wet places. Its range extends from Alaska to Newfoundland and south into Mexico. Plants from the eastern portion of the range have sometimes been treated as <i>G. striata</i> <i></i>var.<i> striata</i>, and those from the west as <i>G. striata</i> <i></i>var.<i> stricta</i> (Scribn.) Fernald. Eastern plants tend to have somewhat narrower leaves and thin¬ner culms than western plants, but the variation appears continuous. In the west, larger specimens are easy to confuse with <i>G. elata</i>. The two species are sometimes found growing together without hybridizing; this and molecular data (Whipple et al. [in prep.]) support their recognition as separate species. The differences between the two in growth habit and stature are evident in the field; they are not always evident on herbarium specimens. In its overall aspect, <i>G. striata</i> also resembles <i>G. pulchella</i>, but it has somewhat more lax panicle branches in addition to smaller spikelets and florets.</p><!--
--><p><i>Glyceria</i> xgatineauensis Bowden is a sterile hybrid between <i>G. striata</i> and <i>G. melicaria</i>. It resembles <i>G. melicaria</i> but has longer (up to 12 cm), less appressed panicle branches and is a triploid with 2n = 30. It was described from a population near Eardley, Quebec. An additional specimen, tentatively identified as G. xgatineauensis, was collected in 1929 from French Creek in Upshur County, West Virginia.</p><!--
--><p><i>Glyceria</i> xottawensis Bowden is a sterile hybrid between <i>G. striata</i> and <i>G. canadensis</i>. It is intermediate between the two parents, and is known only from the original populations near Ottawa. It has sometimes been included in G. xlaxa (Scribn.) Scribn. [=<i>G. canadensis </i>var.<i> laxa</i>]; that taxon often produces viable seed, indicating that it is not a hybrid.</p>
