Gamochaeta antillana

Gamochaeta antillana, the Delicate everlasting, is a species of flowering plant in the sunflower family. It is native to the Greater Antilles and to the southeastern United States (from Florida to Louisiana). It has also become naturalized in other places (South America, Europe, Australia, New Zealand, Texas, California, the Carolinas, etc.).
"Gamochaeta antillana" is an annual herb up to tall, producing a taproot. Leaves are up to long. The plant forms many small flower heads in elongated arrays and also in tightly packed clumps. Each head contains 3–5 purple disc flowers but no ray flowers.
"Gamochaeta antillana" is similar to "G. falcata," and many "Gamochaeta antillana" specimens from the eastern United States have long been misidentified as "G. falcata."
