cymose, open, 5–50 × 5–80 cm; branches dichotomous proximally, often with involucres racemosely arranged distally, tomentose to thinly floccose, rarely glabrate; bracts 3, scalelike, linear to triangular, 0.5–6 mm. |
|
absent or erect, 0.5–3 cm, tomentose. |

Varieties 2 (2 in the flora). Eriogonum marifolium is dioecious, with the two sexes having such markedly different morphology that collectors often consider each to represent a different species. In Oregon, male plants of E. marifolium and E. umbellatum var. haussknechtii can be difficult to distinguish. In El Dorado and Placer counties, California, herbarium specimens of E. marifolium and E. incanum can be difficult to separate, as their distribution ranges overlap there.

Eriogonum nummulare occurs primarily in the Intermountain West from Inyo, Lassen, and Mono counties in California eastward across central and southern Nevada to western and southern Utah. It is found also in northern Mohave and northwestern Coconino counties in Arizona. This species is the food plant of the pallid dotted-blue butterfly (Euphilotes pallescens pallescens) and the Sand Mountain blue butterfly (Euphilotes pallescens arenamontana) is an unprotected subspecies restricted to Sand Mountain in Churchill County, Nevada, where its host plant, Eriogonum nummulare, currently is subject to continued destruction due to unrestricted off-road vehicle activities.
