--><span class="statement" id="st-undefined" data-properties=""><b>Herbs,</b> subshrubs, or shrubs, perennial. <b>Stems</b> erect to spreading or ± prostrate, highly branched, angled or ridged [terete], less than 1 m, becoming woody at least at base, hairy and glandular to almost glabrate [glabrous]. <b>Leaves</b> opposite, palmately compound [rarely scalelike]; stipules persistent, stiff [herbaceous], spinelike, apex spinose or spinulose; petiolules usually present; leaflets (1–)3[–7], inserted on petiole apex, distinct, [linear] lanceolate to ovate [obovate], terminal largest, base cuneate, apex spinose, surfaces stipitate-glandular, glabrate, or glabrous [hairy]. <b>Pedicels</b> in leaf axils, erect, becoming reflexed in fruit. <b>Flowers</b> usually solitary, regular to slightly irregular by twisting of petals; sepals deciduous or persistent, 5, distinct, green to purple, equal, margins undifferentiated or sometimes membranous, apex acute-attenuate, hairy or glandular to glabrate [glabrous]; petals soon deciduous, 5, imbricate, spreading, often twisted (propellerlike), purple to pink [rarely white], ± obovate, base clawed, apex rounded, usually apiculate; nectary rudimentary; stamens 10, ± equal; filaments free, filiform, unappendaged; anthers sagittate; ovary sessile, 5-lobed, 5-locular, hairy and usually glandular; ovules (1–)2 per locule; style persistent, forming beak on fruit; stigma minute. <b>Fruits</b> capsules, ovoid, deeply 5-lobed, loculicidally dehiscent. <b>Seeds</b> usually 1 per locule, brownish to black, flat, ± ovate, seed coat mucilaginous when wet.</span><!--

|discussion=<p>Species 35 (3 in the flora).</p><!--
--><p>Although <i>Fagonia</i> species are perennial, they sometimes facultatively form flowers and reproduce during their first season. The seeds of <i>Fagonia</i> are sticky when wet, which probably aids in dispersal (D. M. Porter 1974b).</p><!--
--><p>Although <i>Fagonia laevis</i> and <i>F. pachyacantha</i> do not cluster next to one another in the trees illustrating a phylogenetic study of the genus (B.-A. Beier et al. 2004b), they were placed together in the taxonomic revision (Beier 2005). Beier reported <i>F. californica</i> Bentham from Arizona and California, considering <i>F. laevis</i> and <i>F. longipes</i> to be synonyms; however, <i>F. californica</i> is a species of Baja California Sur and Sonora and does not occur in the flora area (D. M. Porter 1963). <i>Fagonia</i> californica differs from <i>F. longipes</i> in being prostrate-spreading, not erect to spreading; having leaflets that are elliptic to oblong-lanceolate or oblong, not linear to linear-lanceolate; and having pedicels that are stout and 1–6 mm, not slender and 8–20 mm. It differs from <i>F. laevis</i>, which has erect to spreading stems and linear-elliptic leaflets and is mostly glabrous, not densely stipitate-glandular.</p>
