Narrow-bract rabbitbrush

Bigelowia howardii (Parry ex A. Gray) A. Gray var. attenuata M. E. Jones, Proc. Calif. Acad. Sci., ser. 2, 5: 691. 1895; Chrysothamnus parryi (A. Gray) Greene 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.

Flowering late summer–fall. Mountain slopes, dry, stony soils, sagebrush, pinyon-juniper, ponderosa pine, and aspen communities; 1700–3000 m; Colo., N.Mex., Utah.

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.
