Symphyotrichum bracteolatum (Nutt.) G.L. Nesom
Habit: Perennial herb; rhizome short. Stem: 4--10 dm, +- hairy distally. Leaf: basal and cauline (basal 0 at flower), sessile, 5--15 cm, narrowly lanceolate, acute, generally entire, glabrous to +- hairy. Inflorescence: heads in narrow, many-headed cyme-like cluster; phyllaries +- equal, oblong to ovate, outer +- green throughout, obtuse to acute, inner pale-margined at base, acute, green zone oblanceolate to elliptic. Ray Flower: 20--40, corolla 6--12 mm, white to pink or pink-purple. Fruit: hairy. Chromosomes: 2n=16,32,48,64.
Ecology: Wet places; Elevation: 500--2000 m. Bioregional Distribution: KR, CaR, SN, GB; Distribution Outside California: to British Columbia, Colorado. Flowering Time: Jul--Aug Note: The name S. bracteolatum has nomenclatural priority over S. eatonii (Brummitt 2011 Taxon 60:230).
Synonyms: Aster bracteolatus Nutt.; Aster eatonii (A. Gray) Howell; Symphyotrichum eatonii (A. Gray) G.L. Nesom
Unabridged Note: The type specimen of Aster bracteolatus Nutt. was long overlooked and, upon discovery, was variously interpreted as a specimen of A. hallii A. Gray [=_Symphyotrichum hallii (A. Gray) G.L. Nesom], A. eatonii (A. Gray) Howell [=_S. eatonii (A. Gray) G.L. Nesom], or as a hybrid of these species. Comparison of subsequent collections with the type clarified that the type falls within the circumscription of the taxon treated in TJM1 as A. eatonii [Reveal et al. 2009 Taxon 58:305--306]. The Nomenclature Committee for Vascular Plants declined to recommend that the earlier published A. bracteolatus be rejected in favor of the more widely used A. eatonii (Brummitt 2011 Taxon 60:230). Therefore Symphyotrichum bracteolatum (Nutt.) G.L. Nesom has nomenclatural priority over S. eatonii and is the correct name for the species.
