--><span class="statement" id="st-undefined" data-properties=""><b>Herbs.</b> Stems scattered on horizontal rootstocks, ascending to erect, 10–27(–35) cm, stellate-pubescent to stellate-tomentose. <b>Leaves</b> cauline; petiole 2–5 mm; blade narrowly elliptic to oblanceolate, gradually narrowed to base, 10–30 × 3–6(–8) mm, surfaces stellate-tomentose abaxially, stellate-pubescent adaxially, without simple hairs, lateral veins raised abaxially. <b>Inflorescences</b> terminal, cymes; chasmogamous flowers 2–6 per cyme, cleistogamous in glomerules, 1–6 flowers per glomerule, on lateral leafy branches 1–3 cm, flowering 1–3 months later than chasmogamous. <b>Pedicels</b> (2–)8–14(–22) mm; bracts 1.5–3.5 × 0.3 mm. <b>Chasmogamous</b> flowers: outer sepals linear, 1–3(–4) × 0.4–0.9 mm, inner sepals ovate-elliptic, 5–8 × 2.3–4.5 mm, apex acute; petals obovate, 8–10(–13) × 6–12 mm; capsules 3.7–5.3 × 3–4 mm, glabrous. <b>Cleistogamous</b> flowers: outer sepals rudimentary, 0.2–0.5 × 0.2 mm, inner sepals ovate, 2–2.5 × 1.5–2.2 mm, apex acute; capsules 1.5–2.2 × 1.3–2 mm, glabrous.</span><!--

|discussion=<p>The shorter stature, tiny outer sepals on cleistogamous flowers, and horizontal rootstocks distinguish <i>Crocanthemum propinquum</i> from <i>C. bicknellii</i>, which is often twice as tall, has elongate sepals, and has a caudex. <i>Crocanthemum propinquum</i> is disjunct from the coastal plain of Virginia to the southern Appalachian Mountains of Georgia, North Carolina, and Tennessee.</p>
