Eremothera chamaenerioides is a small herb with an erect, red stem. The lanceolate leaves are marked with red dots. While the basal leaves are present and the stem is short, the plant resembles Oenothera primiveris subsp. primiveris with which it grows. However, the flowers of Eremothera chamaenerioides are minute compared to those of Oenothera primiversi subsp. primiveris. Eremothera chamaenerioides grows in lower elevation arid areas in sandy, rocky soil.
