--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>(20–)40–110(–180) cm. <b>Corms</b> globose to slightly elongate. <b>Stems</b> glabrous. <b>Leaves</b>: basal and lower cauline 3–5-nerved, narrowly oblong-lanceolate to narrowly spatulate-oblanceolate, 120–350 × (2–)4–10(–20) mm (sometimes becoming more densely arranged distally), usually gradually reduced distally, essentially glabrous or sparsely villous, weakly gland-dotted (glandular hairs often not evident, bases of basal often fibrous-persistent). <b>Heads</b> in dense to loose, spiciform arrays. <b>Peduncles</b> usually 0, rarely 1–2 mm. <b>Involucres</b> turbinate-cylindric to turbinate-campanulate, 7–11 × 4–6 mm. <b>Phyllaries</b> in (3–)4–5 series, ovate to oblong, unequal, essentially glabrous, margins with hyaline borders, sometimes ciliolate, apices rounded to obtuse. <b>Florets</b> (4–)5–8(–14); corolla tubes glabrous inside. <b>Cypselae</b> (3.5–)4.5–6 mm; pappi: lengths ± equaling corollas, bristles barbellate.</span><!--

|discussion=<p>Varieties 2 (2 in the flora).</p><!--
--><p><i>Liatris spicata</i> is sold as cut flowers. It also is commonly sold as a garden plant in various genetic permutations (probably derived from <i></i>var.<i> spicata</i>, perhaps from <i>L. lancifolia</i>) and it apparently escapes cultivation. Reports from Arkansas, Connecticut, and Quebec probably reflect plants growing in or escaped from gardens.</p><!--
--><p>A geographic disjunction within <i>Liatris spicata</i> occurs between the coastal plain element (<i></i>var.<i> resinosa</i>) and the inland/montane element (<i></i>var.<i> spicata</i>), although plants morphologically referable to <i></i>var.<i> resinosa</i> occasionally are encountered in montane North Carolina and Tennessee and <i></i>var.<i> spicata</i>-like plants occur in the range of <i></i>var.<i> resinosa</i>. Apparent intergrades between the two taxa are common, especially in Tennessee and Alabama. The geographical gap is widest in Georgia and Alabama. Neither variety occurs naturally west of the Mississippi River, except for a historical record of <i></i>var.<i> spicata</i> in Oregon County, Missouri (Kellogg s.n., MO), where the population has now been genetically “swamped” by <i>L. pycnostachya</i> (G. A. Yatskievych, pers. comm.).</p><!--
--><p>In both <i></i>var.<i> spicata</i> and <i></i>var.<i> resinosa</i>, marked variation (dimorphism) in head size occurs, the large-headed plants apparently occurring in scattered geographic enclaves without a broader geographic pattern. It seems possible that independent populational origins of polyploidy might underlie the variation.</p>
