Eriogonum pusillum is a species of wild buckwheat known by the common name yellowturbans. It is native to the western United States where it grows in sandy soils in a number of habitats, especially in the Mojave Desert and Great Basin.
This is a small annual herb reaching heights of anywhere from 5 to 30 centimeters. The woolly leaves are located at the base of the plant and are about a centimeter long and rounded.
The spindly naked branches of the inflorescence rise and branch, producing cup-shaped flower clusters at each node along the branches. Each tiny, glandular flower is about three millimeters wide at its maximum and turns from bright yellow to orange-red to red.
This is a food plant for the desert tortoise (Gopherus agassizii).

Eriogonum brachypodum is a species of wild buckwheat known by the common name Parry's buckwheat. This annual herb is native to the southwestern United States from California to Utah and especially the Mojave Desert. It grows in sandy and gravelly substrates. It has a skeletonlike spindly stem which branches many times. It can grow 5 to 50 centimeters in height and up to a meter in width. There is an array of rounded, dark-colored leaves around the base. Leaves are a few centimeters long and fuzzy on the undersides. Most of the plant is actually the spreading inflorescence.
