Monolepis pusilla) is the only species of the genus Micromonolepis[2] in the flowering plant family Amaranthaceae, known by the common names small povertyweed and red povertyweed.

It is native to the Western United States, including the Great Basin and surrounding areas, where it grows in sandy scrub, dry valleys, playas, and other open habitat.

It is a somewhat fleshy annual herb producing a branching, slender stem that has a mealy whitish texture when young and turns dull to bright red with age, losing its grainy coat.

NatureServe assessed Micromonolepis pusilla as globally secure (G5) in 2007.

The plant populations in Utah and Washington state were evaluated as "critically imperiled" (S1) and the Colorado population as "possibly extirpated" (SH).
