--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>densely hirsute basally, trichomes primarily simple, to 1 mm, these often mixed with smaller, forked, and/or dendritic ones, glabrescent or sparsely pubescent distally. <b>Stems</b> simple or few to several from caudex, (0.5–)1–4.5(–6.5) dm. <b>Basal</b> leaves: petiole 0.3–3 cm, flattened at base, ciliate; blade oblanceolate to obovate, or linear-lanceolate, (0.5–)1.2–6.5(–10) cm × (2–)3–8(–17) mm, base cuneate to attenuate, apex obtuse to subacute, surfaces pubescent, trichomes usually branched. <b>Cauline</b> leaves: blade lanceolate to linear-lanceolate or oblong, (0.5–)1–3(–4.2) cm × (1–)2.5–7(–10) mm, base strongly sagittate. <b>Fruiting</b> pedicels not appressed to rachis, straight, (3–)5–14(–18) mm, glabrous. <b>Flowers</b>: sepals 1.2–2.5 × 0.6–1 mm, sparsely to densely pubescent; petals (2.5–)3–4(–4.5) × (0.8–)1–1.5 mm; filaments 2–2.5 mm; anthers 0.4–0.5 mm. <b>Fruits</b> (1.5–)2–3.3(–4) cm × (0.7–)1–1.5(–2) mm; style slender, 0.2–0.8(–1) mm. <b>Seeds</b> 0.8–1 × 0.4–0.5 mm.</span><!--

|discussion=<p>Subspecies 2 (2 in the flora).</p><!--
--><p>R. C. Rollins (1993) treated subspp. bursifolia and virgata as distinct species of <i>Halimolobos</i>, but the alleged differences (stems branched basally versus distally, plants cespitose versus non-cespitose, fruits slightly compressed versus terete) do not hold, and the only reliable difference between the two taxa is in the type of trichomes. Therefore, a subspecific, rather than specific, rank is adopted here.</p>
