--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>10–55 cm. <b>Roots</b> few, horizontally spreading, slender, mostly to 0.4 cm diam. <b>Leaves</b> persisting through anthesis, basal, sometimes on basal portion of stem, spreading, linear-oblanceolate to narrowly elliptic, to 21 × 2 cm. <b>Spikes</b> rather loosely to very tightly spiraled, 3–4 flowers per cycle of spiral, occasionally 5 or more in very loose spiral; rachis moderately pubescent, some trichomes capitate, glands obviously stalked. <b>Flowers</b> ochroleucous, ivory, creamy, yellowish, or greenish white, ascending, urceolate to somewhat gaping, claw of lip at pronounced (20–60°) angle to lamina, base cuneate, appearing strongly inflated; sepals distinct to base, 6–14 mm; lateral sepals appressed to petals and lip, straight, separated from dorsal sepal by mostly 0.7–1 mm; petals linear to linear-oblong, 6–13 mm, apex acute to obtuse; lip often more yellow centrally, oblong to ovate, 7–12 × 4–7 mm, margins crenulate, glabrous; veins several, branches parallel; basal calli incurved, prominent, very rarely conic, 1–2 mm; viscidia linear; ovary 3–7 mm. <b>Seeds</b> monoembryonic. <b>2n</b> = 30.</span><!--

--><p><i>Spiranthes</i> ×steigeri was described as a hybrid of <i>S. cernua</i> and <i>S. romanzoffiana</i>, but additional study (P. M. Catling 1984) has shown the plants to be referable to <i>S. ochroleuca</i>.</p><!--
