|discussion=<p>Variety lasiophylla occurs over most of the range of the species in Louisiana and Texas; <i></i></i>var.<i><i> pycnostachya</i> occurs in the northern counties of those states and, apparently, also sporadically southward through the range of <i></i></i>var.<i><i> lasiophylla</i>, at least in Texas, where it grows in drier habitats than <i></i></i>var.<i><i> lasiophylla</i>. In Louisiana and Texas, <i></i></i>var.<i><i> pycnostachya</i> begins flowering in mid-June and continues through July (through August more northward in its range), usually well before the main flowering period of <i></i></i>var.<i><i> lasiophylla</i>. Despite these indications of reproductive isolation, apparent intermediates are commonly encountered (usually these are plants with dense cauline vestiture but sparsely pubescent to glabrate leaves, compared to the densely piloso-puberulent stems and leaves of typical <i></i></i>var.<i><i> lasiophylla</i>). Most of the plants with reduced vestiture in the range of <i></i></i>var.<i><i> lasiophylla</i> also have the later flowering period.</p><!--
--><p>In Pearl River and Hancock counties, Mississippi, and St. Tammany and Washington parishes, Louisiana, plants with vestiture of <i></i></i>var.<i><i> lasiophylla</i> have phyllaries with rounded to slightly acute apices, different from the rest of the species. These were named <i>Liatris</i> serotina, and it seems likely that they originated as hybrids between <i></i></i>var.<i><i> lasiophylla</i> and <i>L. spicata </i>var.<i> resinosa</i>, whose ranges meet in that area. Some plants of <i>L. spicata</i> in Illinois, Indiana, and Minnesota also develop cauline vestiture; the tendency apparently is evolutionarily independent of that in <i></i></i>var.<i><i> lasiophylla</i>.</p>
