--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>mostly epiphytic, sometimes terrestrial, to 100 cm (excluding inflorescence). <b>Stems</b> modified into prominent, compressed pseudobulbs, subtended by 1–3 leafy bracts. <b>Leaves</b> 3, apical [2, lateral] on pseudobulb, 2 lateral; blade linear-lanceolate, 60–100 × 3–5 cm, not leathery. <b>Inflorescences</b> erect-arching to pendent, 100–250 cm; bracts 5–8 mm. <b>Flowers</b> yellow with numerous small brown spots; sepals reflexed, oblong-elliptic, clawed, 16 × 3.5–5.5 mm, margins somewhat undulate, apex acute; petals reflexed at least at apex, oblong-elliptic, clawed,10–14 × 5–7 mm, apex acute; lip mostly yellow with brown patches near lip callus, 11–15 × 8.5–11 mm, apiculate, middle lobe about as wide as combined lateral lobes, isthmus 5–6 mm wide; callus of central ridge with 3–5 paired lateral ridges; column yellow, with pair of erect, axe-shaped, apical wings; pedicellate ovary [15–]24 mm. <b>Capsules</b> pendent, ellipsoid, 18–20 × 8–20 mm.</span><!--

|discussion=<p>In describing <i>Oncidium</i> floridanum, O. Ames (1924) stated that the Florida plants were distinct from O. sphacelatum Lindley but failed to recognize the affinities of the Florida plants to the Mexican and Central American <i>O. ensatum</i>. Several differences between the plants from Florida and a cultivated specimen of <i>O. ensatum</i> from Guatemala were cited by R. P. Sauleda and R. M. Adams (1989). My study of <i>Oncidium ensatum</i> throughout its range reveals no features consistent enough to warrant recognizing the Florida populations as a separate taxon.</p>
