Eugenia fajardensis (also called Guayabote de Costa, or Fajardo Guayabacón) is a species of plant endemic to Puerto Rico. Today it is limited to the northeastern corner of the island, specifically in the municipality of Fajardo within the Northeast Ecological Corridor, and to the island-municipalities of Vieques and Culebra. First discovered by German botanist Paul Sintenis between 1884 and 1887, it remained largely forgotten due, partly, to the fact that Sintenis' first set of his Puerto Rican collections was mostly destroyed at Dahlem (Berlin) during the Second World War. In 2005 Puerto Rican botanists Juan Carlos Trejo, with Miguel Vives, Marcos Caraballo and Tomás Carlo "re-discovered" the species in Vieques Island.

Compounds documented for Myrcianthes fragrans across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
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 Myrcianthes fragrans has left across the world's sequence archives.

Where the DNA of Myrcianthes fragrans 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.
