|discussion=<p><i>Danthonia sericea</i> is restricted to the eastern United States. It grows mostly on sand barrens and in open woods on dry soils. A less common form, with glabrous foliage and lemma backs, is found in bogs, seepage areas, and low moist areas adjacent to lakes and rivers and has been called <i>D. sericea</i> var. epilis (Scribn.) Gleason. In their study of these ecotypes, Quinn and Fairbrothers (1971) state that "field differences in growth form do not persist under transplant garden and greenhouse conditions." Similar patterns of infraspecific variation are also seen in the leaf and lemma vestiture of <i>D. spicata</i> and <i>D. californica</i>, but the genetic basis of this variation is probably not taxonomically significant.</p>
