Cinnamomum parthenoxylon is an evergreen tree in the genus Cinnamomum, 10 - tall. It is native to South and East Asia (Bhutan, Myanmar, Cambodia, China, India, Indonesia, Laos, Malaysia, Nepal, Philippines, Thailand, and Vietnam). In Vietnam, the tree is considered Critically endangered. In English, C. parthenoxylon is known as Selasian wood, saffrol laurel, or Martaban camphor wood. It has the outdated heterotypic synonym Laurus porrecta (Roxb.). The species name parthenoxylon derives from parthenos xylon (), meaning "virgin wood". The common name in Spanish is alcanforero amarillo ("yellow camphor") and it is thought to be the tree known as (mreah prew phnom).

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 Cinnamomum parthenoxylon has left across the world's sequence archives.

07Deep time~9.96 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.

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.

09Environmental DNA11 detections
Where the DNA of Cinnamomum parthenoxylon 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.
