Herbs usually winter-annual, sometimes perennial, glabrous, glandular puberulent, strigillose, and/or villous, sometimes more villous distally, hairs sometimes very curly, especially on flower parts; from a taproot or relatively long, fleshy roots. |
central stem usually erect, usually thickened at base and spongy, branched or unbranched, branches few–several, slender, decumbent to ascending, from base, usually encircling central stem in older plants, 10–40(–100) cm. |
in a basal rosette and cauline, rosette usually well developed (except subsp. howellii), basal 5–25 × 1–5 cm, cauline 4–12(–18) × 0.5–4 cm; petiole 1.5–8 cm; blade rhombic-obovate, lanceolate, or oblanceolate, margins subentire, dentate, or pinnatifid. |
1–several opening per day near sunset; buds nodding, weakly or strongly quadrangular or fluted in distal 1/2, with free tips 0–9 mm; floral tube 20–40 mm; sepals (13–)15–35 mm, not spotted; petals white, fading pink to deep pink, broadly obovate or obcordate, 15–44 mm; filaments 8–15 mm, anthers 5–14 mm; style 35–60 mm, stigma exserted beyond anthers at anthesis. |
spreading, straight to curved, becoming somewhat woody in age, cylindrical to slightly 4-angled, widest toward base, tapering from base to apex, (15–)30–80 × 1.5–5 mm; sessile. |
numerous, in 1 row per locule, buff with dark spots or black, narrowly obovoid, 1.5–2.8 mm. |
