It is native to eastern California and western Nevada, particularly the Mojave Desert region, where it is common to abundant, and even sometimes weedy. It is also known from southern Oregon. The plant grows in sandy habitats such as desert flats and sagebrush. It also grows in pinyon-juniper and montane conifer woodlands. It is an annual herb that grows 30 to 40 centimeters tall. Leaves are located at the base of the stem, woolly, and oval or rounded in shape. The top of the stem is occupied by a branching inflorescence bearing many widely spaced clusters of flowers. Each individual flower is about a millimeter wide and light yellow in color. Flowers bloom from April to November.
Eriogonum latens is a species of wild buckwheat known by the common name Inyo buckwheat. It is native to the western Great Basin region, in the eastern slopes of the Sierra Nevada and the Inyo Mountains of California and the White Mountains, which extend just into western Nevada. It is an uncommon member of the flora in the sagebrush and woodlands of these mountains, where it grows in granitic sandy soils.
