Sidalcea diploscypha (Torr. & A. Gray) A. Gray
Habit: Annual 4--6 dm. Stem: stellate-puberulent, long-fine-bristly. Leaf: bristly-puberulent; stipules of mid- to upper-stem divided into >= 2 linear lobes, generally > 10 mm; lobes of upper leaves narrow, middle lobe entire or with middle tooth >> lateral 2. Inflorescence: flower clusters crowded; axis generally not glandular, multicellular hairs generally few or 0; bracts 8--12 mm, divided into 2--4 linear lobes, finely bristly, generally involucre-like in age, >= calyx. Flower: calyx 8--12 mm, lobes lanceolate, long-acuminate, adaxially often with narrow purple line or spot at base, abaxially bristly and stellate-puberulent, generally not glandular, multicellular hairs generally few or 0; petals 20--35 mm, +- 19 mm wide, dark pink, dark spot occasionally at base, tip minutely fringed; filaments fused to tip. Fruit: segment +- 2.5 mm, glabrous, occasionally +- pink when fresh, back net-veined, beak 0.
Ecology: Grassland, open woodland, valleys, occasionally near vernal pools, generally serpentine; Elevation: < 840 m. Bioregional Distribution: NCoRO, CaRF, n&c SNF, ScV, CCo, SnFrB; Distribution Outside California: western Oregon. Flowering Time: Apr--May Note: Some plants +- intermediate to Sidalcea keckii, but species distinct by molecular evidence (Hill 2009); study needed.
Unabridged Note: Plants in Butte, Colusa, Lake, Napa, Solano, Yolo cos. sometimes +- intermediate to Sidalcea keckii, suggesting introgression but species distinct by molecular evidence; study needed.
