--><span class="statement" id="st-undefined" data-properties="">Annuals; (glaucous), usually glabrous throughout (sometimes stem bases pubescent). <b>Stems</b> unbranched or branched distally, 1.7–10.6 dm, (trichomes 0.05–0.5 mm). <b>Basal</b> leaves (soon withered); rosulate; petiolate; blade similar to cauline. <b>Cauline</b> leaves: blade broadly ovate to broadly oblong or lanceolate, 2–15 cm × 10–80 mm, (smaller distally), base amplexicaul, margins entire, (apex acute to acuminate or rounded). <b>Racemes</b> ebracteate, (dense or lax). <b>Fruiting</b> pedicels divaricate-ascending, (straight), 4–7 mm. <b>Flowers</b>: calyx campanulate; sepals (erect), purplish, 4–9 mm, (lateral pair rarely with subapical callus, 0.1–0.3 mm), not keeled; petals (widely spreading to somewhat reflexed), magenta (with deep purple center), 11–21 mm, blade 6–12 × 5–11 mm, margins not crisped, claw 5–10 mm, narrower than blade; stamens tetradynamous; filaments: median pairs (distinct), 5–7 mm, lateral pair 3–5 mm; anthers (all) fertile, 3–4 mm; gynophore 0.7–1.5 mm. <b>Fruits</b> ascending, smooth, straight, flattened, 6–11.4 cm × 2–3 mm; valves each with prominent midvein; replum straight; ovules 56–92 per ovary; style 1–2.5 mm; stigma strongly 2-lobed. <b>Seeds</b> broadly oblong, 2–2.5 × 1–1.3 mm; wing 0.2–0.3 mm wide, continuous.</span><!--

|discussion=<p><i>Streptanthus maculatus</i> is distributed in Arkansas in Garland, Hot Springs, Montgomery, Pike, Polk, Pulaski, and Saline counties; in Oklahoma in Latimer, Le Flore, McCurtain, and Pushmataha counties; and in Texas in Anderson, Cherokee, Gregg, and Smith counties.</p><!--
--><p>R. C. Rollins (1993) divided <i>Streptanthus maculatus</i> into two subspecies based on the presence versus absence of the subapical callus on sepals and on leaf shape. Subspecies maculatus was said to differ from subsp. obtusifolius by the absence (versus presence) of the sepal callus and by having lanceolate (versus broadly ovate) cauline leaves. These highly variable characters do not covary.</p>
