--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>(0.3–)0.5–1(–1.2) m, with caudex or usually compact rootstocks or rhizomes to 10(–30) cm × 4 mm. <b>Stems</b> erect, sometimes supported by other vegetation, sometimes proximally decumbent and often rooting to erect, roughly minutely- or long-stellate-hairy, hairs spreading, usually on swollen bases, minutely hairy to glabrate distally. <b>Leaves</b> mostly cauline, evenly distributed, not concentrated at stem base, gradually reduced distally; petiole (1–)5–10(–15) cm, those of proximal leaves 4 times as long as blade, reduced distally to 1/2 times to as long as blade; blades: proximal usually lobed, distal palmately (5–)7-lobed, (3–)5–12(–15) cm wide, base with wide sinus to truncate, margins crenate-serrate, lobe tips oblong, usually 3-toothed (sometimes entire), distalmost 3–5-parted; surfaces stellate-puberulent, sometimes with some simple hairs. <b>Inflorescences</b> erect, unbranched or branched, 8–15(–30)-flowered, sometimes 1-sided; proximalmost bract usually leaflike, 15 × 12 mm, distal bracts linear, 3 mm, shorter than pedicel. <b>Pedicels</b> 2–5(–10) mm. <b>Flowers</b>: calyx 5–7 mm, to 7–10 mm in fruit; petals pink to pale purple, pistillate usually (5–)10–15 mm, bisexual (15–)20–25 mm; stigmas (6 or)7 or 8. <b>Schizocarps</b> 6–8 mm diam.; mericarps (6 or)7 or 8, 3–4 mm; prominently reticulate-veined, pitted, margins and back rugose-pitted but less so on back, sometimes glabrous, mucro 0.5–0.8 mm. <b>Seeds</b> 1.5 mm. <b>2n</b> = 20, 40, 60.</span><!--

|discussion=<p>Subspecies asprella has been confused with <i></i>subsp.<i> nana</i>, <i>Sidalcea celata</i>, <i>S. elegans</i>, and <i>S. glaucescens</i>, and it previously has been placed within <i>S. malviflora</i>. Taller individuals can be confused with <i>S. celata</i> and <i>S. gigantea</i>; the adaxial leaf surfaces of <i>S. celata</i> generally have simple or two-branched hairs and those of the others have stellate hairs. <i>Sidalcea gigantea</i> always has long, retrorse bristle hairs at the stem base, and well-developed rhizomes. <i>Sidalcea celata</i> usually has dense, short, retrorse simple hairs at the stem base and rarely some stellate hairs; <i></i>subsp.<i> asprella</i> always has stellate hairs at the stem base, but they can be less dense and short-scabrous or longer and softer. All three taxa occur in Shasta County, California, and some specimens from there may not be easily determined to species; young plants of <i>S. gigantea</i> may be easily mistaken as <i></i>subsp.<i> asprella</i> before the stems and rhizomes are fully developed, and the fruits essentially match in both species. Subspecies asprella appears to be replaced by <i></i>subsp.<i> nana</i> in northern California and Oregon, and it is especially difficult to be certain of identifications in that area.</p>
