Alniaria folgneri (syn. Sorbus folgneri), Folgner's whitebeam, is a species of flowering plant in the family Rosaceae, native to central China. A small tree, the abaxial side of its soft leaves are covered in a silvery-white tomentose layer. Its autumn foliage often turns golden pink, set off by the white undersides, but the intensity of the color varies from year to year. Its cultivar 'Emiel' has gained the Royal Horticultural Society's Award of Garden Merit.

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 Sorbus folgneri has left across the world's sequence archives.

07Deep time11.6–5.33 Ma
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.

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 solid bar is the fossil range: the span between the oldest and the youngest fossil that palaeontologists have assigned to Sorbus folgneri. Above itBeside it, each dot is one dated fossil find — few enough to count, so they are drawn individually rather than as a graph.

Where the DNA of Sorbus folgneri 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.
