--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>rhizomatous; rhizomes yellow, unbranched, horizontal, 0.5–1 cm or more diam., nodes articulate, each segment bearing 1 dark, contrasting, ± deltate scale leaf, scales brown and papery, caducous, each leaving dark, linear scar perpendicular to growing axis. <b>Stems</b> twining counterclockwise, ± polygonal to terete, 1–4 m, surface longitudinally grooved. <b>Leaves</b> alternate proximally (variation expected) and distally, 3–11 × 3–9 cm; petiole 3–8 cm, base not clasping; blade sometimes glandular, 7–9-veined, ovate-cordate to deltate, glabrous, margins entire or repand, apex acuminate. <b>Staminate</b> inflorescences (1–)2–5 in leaf axils, terminal, spicate to highly branched; cymes sessile, bearing 1–3 sessile flowers, bracteolate, internodes between cymes 2–5 mm, bracteoles linear-lanceolate, ca. 1 mm; rachis to 30 cm, secondary axes to 15 cm, subtended by linear-lanceolate bracts ca. 1–2 mm. <b>Pistillate</b> inflorescences borne singly, 4–20 or more-flowered, 4–25 cm, internodes 7–12 mm. <b>Staminate</b> flowers: perianth yellowish orange, rotate-campanulate to funnelform, 1–2 mm; tepals ± glandular, oblong, margins hyaline, apex (acute to) rounded or truncate; stamens in 2 equal whorls, inwardly curved; anthers ca. 1/3 length of filaments, thecae connate. <b>Pistillate</b> flowers: perianth as in staminate flowers; staminodes 6, differentiated into anthers and filaments, less than 1/2 size of fertile stamens. <b>Capsules</b> greenish gold, ovoid, obreniform, or oblong, 1.5–2.8 × 1.5–2.5 cm. <b>Seeds</b> 9–13 mm.</span><!--

|discussion=<p><i>Dioscorea floridana</i> is undoubtedly a close relative of <i>D. villosa</i>, but because it is identifiable using characters that vary discretely, with states not manifest in plants occupying similar habitats outside of its range, I have chosen to retain it at the rank of species.</p>
