Gamochaeta antillana, the delicate everlasting, is a species of flowering plant in the family Asteraceae. 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.).Guy L. Nesom 2004. New distribution records for Gamochaeta (Asteraceae: Gnaphalieae) in the United States. Sida 21(2): 1175–1185.Zuloaga, F. O., O. Morrone, M. J. Belgrano, C. Marticorena & E. Marchesi. (eds.) 2008. Catálogo de las plantas vasculares del Cono Sur. Monographs in Systematic Botany from the Missouri Botanical Garden 107(1–3): i–xcvi, 1–3348. Gamochaeta antillana is an annual herb up to 40 cm tall, producing a taproot. Leaves are up to 4 cm 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.Flora of North America, Gamochaeta antillana (Urban) Anderberg, 1991. Delicate everlasting Gamochaeta antillana is similar to G. falcata, and many Gamochaeta antillana specimens from the eastern United States have long been misidentified as G. falcata.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Gamochaeta antillana has left across the world's sequence archives.

07Deep time~0.56 Ma lineage
How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

DNA clock origin0.56 Ma TimeTree
When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

Where the DNA of Gamochaeta antillana was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
