A shrubby plant, the leafy branches of Eriogonum molle reach about a foot or two high.

The involucres are few, many-flowered, and corymbose on top of stout, naked peduncles that are a foot or two long.

[2] This species was discovered by Edward Lee Greene on a journey to the northern end of Cedros Island.

[2][3] This plant is only known from the rocky, extreme northern end of Cedros Island, scattered along summits and ridges.

[1] It shares a community with primarily succulent species, such as Agave sebastiana, Dudleya albiflora and Dudleya pachyphytum, all fed by the marine fog that frequently covers the northern end of the island.
