Gamochaeta stagnalis, the Desert cudweed, is a species of flowering plant in the sunflower family. It is native to Mexico, Guatemala, and the southwestern United States (California, Arizona, New Mexico). [3] [4] [5]

Gamochaeta stagnalis is an annual herb up to 35 cm (14 in) tall, producing a slender taproot. Leaves are up to 3 cm (1.2 in) long. The plant forms many small flower heads in tightly packed clumps. Each head contains 3–4 purple disc flowers but no ray flowers. [3] [6]

Gamochaeta stagnalis is very similar to G. purpureum and some G. stagnalis specimens (especially from Arizona) have been misidentified as that species. [3]
