01Narrative
Gamochaeta simplicicaulis, the simple-stem cudweed or simple-stem everlasting, is a species of flowering plant in the sunflower family. It is native to South America and has become naturalized in Australia, New Zealand, and the southeastern United States (from Alabama to Virginia).Biota of North America Program 2014 county distribution mapZuloaga, F. O., O. Morrone, M. J. Belgrano, C. Marticorena & E. Marchesi. (eds.) 2008. Catálogo de las plantas vasculares del Cono Sur.

Checklist of the Plants of the Guiana Shield (Venezuela: Amazonas, Bolivar, Delta Amacuro; Guyana, Surinam, French Guiana). Contributions from the United States National Herbarium 55: 1–584 Gamochaeta simplicicaulis is an annual herb up to 85 cm tall. Leaves are up to 9 cm long, green and hairless on the upper surface but appearing white on the underside because of many woolly hairs. The plant forms many small flower heads in elongated arrays and also in tightly packed clumps. Each head contains 2–3 yellow disc flowers but no ray flowers.Flora of North America, Gamochaeta simplicicaulis (Willdenow ex Sprengel) Cabrera, 1961. Simple-stem cudweed

05DNA & barcoding1 sequences
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 simplicicaulis has left across the world's sequence archives.

07Deep time~0.3 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 origin0.3 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.
