--><span class="statement" id="st-undefined" data-properties=""><b>Caudex </b>branches short. <b>Stems</b> tufted, (1–)1.5–7.5 dm; base 1–5 mm diam., moderately to densely septate-glandular. <b>Leaves</b> sparsely to moderately hairy; basal (3–)6–30 cm, leaflet pairs (1–)2–4; terminal leaflet broadly obovate to rhombic-elliptic, (1–)1.5–7(–8) × 1–5 cm, teeth usually double (irregularly single in <i></i>var.<i> viscida</i>), (4–)6–18(–20) per side, apex rounded to obtuse; cauline 0–3, developed or reduced, leaflet pairs 1–4. <b>Inflorescences</b> (2–)5–40-flowered, leafy or not, open or of congested clusters terminating branches, (1/10–)1/5–3/4 of stem, usually wide (narrow in <i></i>var.<i> viscida</i>), branch angles (15–)20–55°. <b>Pedicels</b> 1–10 (proximal to 30) mm, not or sparsely short-hairy, predominantly septate-glandular. <b>Flowers</b> opening widely; epicalyx bractlets linear-lanceolate to elliptic, 1.5–7(–8) × 0.5–2.5(–3) mm; sepals spreading or reflexed, (3–)4–11 mm, apex usually broadly obtuse with mucronate tip, sometimes acute; petals not overlapping, spreading or reflexed, cream-white to yellow, narrowly to broadly obovate or ovate to nearly round, 2–6.5 × 1.5–5.5 mm, shorter than or equal to sepals; filaments 0.5–2 mm, anthers 0.5–1 mm; styles thickened, 1–1.5 mm. <b>Achenes</b> reddish brown, 0.9–1.5 mm.</span><!--

|discussion=<p>Varieties 4 (4 in the flora).</p><!--
--><p>Even with the removal of most of the subspecies of <i>Potentilla</i> glandulosa treated by Keck, <i>Drymocallis glandulosa</i> encompasses an inordinate range of variation. This is because of the apparently clinal variation between the coastal extreme (<i></i>var.<i> wrangelliana</i>), with leafy inflorescences and broad cream-white petals, the montane <i></i>var.<i> reflexa</i>, with less leafy inflorescences and narrow yellow petals, and the transitional interior <i></i>var.<i> glandulosa</i>. Variety reflexa, in turn, intergrades in the mountains of southern California with <i></i>var.<i> viscida</i>, which is anomalous in <i>D. glandulosa</i> with its narrow inflorescences and irregularly single-toothed leaflets. Variation outside of California is unclear, with no evident pattern to differences in petal size and color; these have largely been assigned to <i></i>var.<i> glandulosa</i>.</p><!--
--><p>At its most distinctive, <i>Drymocallis glandulosa</i> is a robust, densely glandular plant with widely branched leafy inflorescences (except <i></i>var.<i> viscida</i>), relatively short, stout pedicels, broad sepals with rounded, mucronate tips (except <i></i>var.<i> viscida</i> and sometimes <i></i>var.<i> reflexa</i>) that are often significantly enlarged in fruit, and non-overlapping petals that are shorter than to scarcely equal to the sepals. The relatively large achenes are blunter and redder than those of most other species of <i>Drymocallis</i>, as discussed by J. Clausen et al. (1940).</p>
