Pentaclethra macroloba is a large and common leguminous tree in the genus Pentaclethra native to the wet tropical areas of the northern Neotropics, which can form monocultural stands in some seasonally flooded habitats. It has giant, bipinnate leaves shaped like feathers. It uses seed dispersal by water to establish itself in new areas, having floating seeds that are left behind after the waters recede after floods or tides. It has hard timber which is not very resistant to rot in the tropics, but it can be treated, has a pretty pink-red colour when dry, and has a number of uses. Oil used in cosmetics is extracted from the large seeds. In the northern Amazon region the bark is used in herbal medicine as an antivenom, and in the Guianas the bark has been used as a fish poison. Despite their toxicity, the seeds are eaten by variegated squirrels, parrots and macaws, and serve as the nurseries of the larvae of the moth Carmenta surinamensis.

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 Pentaclethra macroloba has left across the world's sequence archives.

07Deep time~2.94 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.

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.
