Ivesia sericoleuca (Rydb.) Rydb.
NATIVE
Habit: Plant tufted, +- green to white-hairy; caudex 0--few-branched. Stem: generally decumbent to ascending, 15--45 cm. Leaf: 10--20 cm; sheathing bases densely strigose; leaflets 20--35 per side, lobes 1--4, 3--15 mm, elliptic to oblanceolate; cauline leaves 3--8. Inflorescence: open; clusters +- 5--20, 10--20 mm wide, +- head-like, +- 5--10-flowered; pedicels < 3 mm (except lowest), straight. Flower: 10--15 mm wide; hypanthium length +- 1--2 × width; petals 4--7 mm, > sepals, wide-obovate to -obcordate, white; stamens generally 20; pistils 2--7. Fruit: 2--3 mm, smooth, brown. Chromosomes: n=14.
Ecology: Dry, generally volcanic meadows; Elevation: 1300--2320 m. Bioregional Distribution: n SNH, s MP (Sierra Valley). Flowering Time: May--Sep
Unabridged Note: Plants from Truckee River drainage generally less hairy, with more open inflorescence, smaller flowers. Similar to Ivesia pityocharis Ertter (Nevada, flatter hypanthium, 8--20 pistils).
