|discussion=<p><i>Puccinellia tenella</i> is a halophytic, circumpolar subarctic and low arctic species. It is found above the high tide zone on sandy spits, in salt marshes, in silty soils, and among granitic rocks to 30 m above sea level. The above description applies to <i>P. tenella</i> subsp. langeana (Berlin) Tzevlev, the only subspecies in the Flora region. <i>Puccinellia</i> alaskana Scribn. &; Merr., considered a subspecies of P. langeana (Berlin) T.J. Sørensen ex Hulten [= <i>P. tenella</i>] by Sørensen (1953), has acute lemmas and hairs on the palea. It is discussed under <i>P. pumila</i> (see p. 471).</p>
