Sidalcea asprella Greene subsp. asprella
Habit: Plant 3--10(12) dm, caudex present or 0, rhizomes < 10(30) cm. Stem: often weak, on other pls, base stellate-hairy. Leaf: basal, cauline, all +- alike, gradually reduced upwards, +- lobed, lobe tips generally toothed; adaxially with generally simple hairs to stellate-puberulent. Inflorescence: erect, open, elongate, occasionally 1-sided, generally 8--15(30)-flowered; lowest bract generally leaf-like, +- 15 mm, 12 mm wide, bracts above linear, +- 3 mm, generally forked, < flower stalk; flowering stalks 2--5(8) mm, stout. Flower: calyx 7--10 mm, densely stellate-puberulent, lobes generally 6 mm, 3.5 mm wide, veins 5--7, 3 prominent; petals of bisexual flowers 2--2.5 cm, of pistillate generally 1--2 cm. Fruit: segments (6)7--8, beak +- 0.5--0.8 mm. Chromosomes: 2n=20,40,60.
Ecology: Open woodland, dry rocky slopes, foothill woodland, lower conifer forest; Elevation: (100)200--900(1800) m. Bioregional Distribution: NW, CaR, n&c SNH; Distribution Outside California: southwestern Oregon. Flowering Time: May--Jun
Synonyms: Sidalcea malviflora (DC.) A. Gray subsp. asprella (Greene) C.L. Hitchc.
Unabridged Note: Confused with Sidalcea asprella subsp. nana, Sidalcea elegans, Sidalcea glaucescens. Confused especially with Sidalcea gigantea, Sidalcea celata; needs study. May be mistaken easily with young plants of Sidalcea gigantea before stems, rhizomes fully developed, and fruits +- match in both species. Leaves of Sidalcea celata generally have adaxially simple or 2-branched hairs, those of the other 2 species have minute stellate hairs. Sidalcea gigantea has long reflexed bristles at stem base and well-developed rhizomes; Sidalcea celata generally has shorter simple hairs at stem base but rarely has similar stellate hairs instead; Sidalcea asprella has stellate hairs, but hairs can be short scabrous or longer-softer at stem base. All 3 species occur in Shasta Co., some specimens there may not be easily determined to sp. The typical subsp. appears to be replaced by Sidalcea asprella subsp. nana in NW, CaR, Oregon; it is especially difficult to be certain of identifications in this area.
