Ericameria parryi var. attenuata
Phytologia 75: 88. 1993.
Common names: Narrow-bract rabbitbrush
Endemic
Basionym: Bigelowia howardii var. attenuata M. E. Jones Proc. Calif. Acad. Sci., ser. 2, 5: 691. 1895
Synonyms: Chrysothamnus parryi subsp. attenuatus (M. E. Jones) H. M. Hall & Clements
Plants 20–60 cm. Leaves moderately crowded, green; blades 1-nerved, linear, 20–40 × ca. 1 mm, faces glabrous or sparsely hairy, eglandular, somewhat viscid; distalmost shorter than arrays. Heads 5–10 in compact, racemiform arrays. Involucres 11–12.5 mm. Phyllaries 13–22, apices erect, attenuate. Florets 5–7; corollas clear yellow, 10–11 mm, tubes glabrous, throats gradually dilated, lobes 1.5–2 mm. 2n = 18.
Phenology: Flowering late summer–fall.
Habitat: Mountain slopes, dry, stony soils, sagebrush, pinyon-juniper, ponderosa pine, and aspen communities
Elevation: 1700–3000 m
Distribution
Colo., N.Mex., Utah.
Discussion
S. L. Welsh et al. (1987) noted that characteristics used to distinguish var. howardii from var. attenuata (distalmost leaves overtopping arrays and pale-colored florets) fail as diagnostic features for plants from Utah.
