--><span class="statement" id="st-undefined" data-properties=""><b>Herbs,</b> usually annual, rarely perennial, with taproot. <b>Stems</b> prostrate or slightly ascending, 10–40 cm, glabrous. <b>Leaves</b> opposite; stipules distinct, linear-subulate, usually divided into 3 linear segments, 1–2 mm, glabrous; petiole 1–2 mm, glabrous; blade oblong or elliptic-oblong, 4–15 × 2–3 mm, base asymmetric to nearly symmetric, obtuse, margins entire, apex acute to mucronate, surfaces green to reddish flushed, glabrous; only midvein conspicuous. <b>Cyathia</b> solitary or in small, cymose clusters at distal nodes; peduncle 0.5–3 mm. <b>Involucre</b> obconic-campanulate, 1.2–1.6 × 1.5–1.7 mm, glabrous; glands 4, green to red, slightly concave, elliptic, oblong, or subcircular, 0.3–0.5 × 0.4–0.6 mm; appendages white or pink, semilunate, fringing edge of gland, sometimes rudimentary, (0–)0.1–0.5(–0.7) × 0.5–0.8 mm, distal margin crenate to entire. <b>Staminate</b> flowers 5–16. <b>Pistillate</b> flowers: ovary glabrous; styles 0.2–0.3 mm, 2-fid 1/2 length. <b>Capsules</b> broadly ovoid, 2–2.1 × 2.3–2.5 mm, glabrous; columella 1.5–2 mm. <b>Seeds</b> ashy white, plumply ovoid, terete to bluntly subangled in cross section, 1.5–1.9 × 1–1.2 mm, smooth or minutely pitted, with smooth brown line from top to bottom on adaxial side.</span><!--

|discussion=<p><i>Euphorbia bombensis</i> is similar and closely related to <i>E. cumulicola</i>, <i>E. geyeri</i>, and <i>E. polygonifolia</i>. It differs notably from <i>E. polygonifolia</i> in its smaller, plumply ovoid seeds. L. C. Wheeler (1941) suggested that where <i>E. bombensis</i> and <i>E. polygonifolia</i> are sympatric, <i>E. bombensis</i> grows farther away from the shore. <i>Euphorbia bombensis</i> is usually distinguished from <i>E. cumulicola</i> by the latter's smaller, isomorphic leaves that lack any fleshiness, smaller seeds, and diffuse growth habit. <i>Euphorbia bombensis</i> differs from <i>E. geyeri</i> in its usually shorter, less conspicuous involucral gland appendages and its geographic restriction to the coastal plain. However, Wheeler pointed out that plants of <i>E. bombensis</i> from Texas have more or less conspicuous involucral gland appendages. Examination of specimens confirmed that <i>E. bombensis</i> occasionally has conspicuous involucral gland appendages, and because of this, <i>E. bombensis</i> and <i>E. geyeri</i> are difficult to distinguish in Texas. This clade of closely related, sand and dune specialists requires further study.</p>
