--><span class="statement" id="st-undefined" data-properties=""><b>Annuals,</b> 4–30 cm; taprooted. <b>Stems</b> 1–50+, initially scapiform, later elongate and leafy (after rosette leaves wither), erect, eglandular or stipitate-glandular, especially near heads. <b>Leaves</b> initially produced basally (rosettes); later leaves cauline; sessile or petiolate; blades oblanceolate to spatulate, 1.5–18 cm, usually irregularly pinnately lobed, terminal lobes often denticulate, faces glabrous, eglandular or loosely glandular-villous; cauline (appearing opposite on late-season stems), narrowly oblanceolate to linear, mostly entire. <b>Heads</b> borne singly. <b>Peduncles</b> from rosettes (early) or axillary or terminal on stems (later). <b>Involucres</b> 4.5–8 mm. <b>Phyllaries</b> 9–15, reflexed in fruit, lanceolate, midveins obscure, apices acute. <b>Florets</b> 8–35; corollas yellow, often purplish abaxially, 5–12 mm. <b>Cypselae</b> dark reddish brown, narrowly obconic, 1.5–2.3 mm, 15–20-ribbed; pappi of 5, hyaline, rounded outer scales 0.5–1 mm plus 5, scabrous inner bristles 4–6 mm. <b>2n</b> = 10, 20.</span><!--

|discussion=<p><i>Krigia virginica</i> is introduced in British Columbia. It grows in the Eastern deciduous forest biome, tallgrass prairie, and southeastern Coastal Plain. Its weedy habit may lead to introductions outside the present range.</p><!--
--><p>The tetraploid populations of <i>Krigia virginica</i> are believed to have arisen through autoploidy; they are morphologically indistinguishable from the diploids. A single origin for this autoploid event is suggested by the chloroplast DNA studies by K. J. Kim et al. (1992b, 1992c), with marked genetic divergence of the tetraploids having occurred since their origination. Plants collected late in the season have a branching habit remarkably unlike the scapiform vernal form.</p>
