01Narrative

Psychotria mariniana, the forest wild coffee or kōpiko, is a tree endemic to Hawaii. The plant belongs to the Rubiaceae (coffee) family, subfamily Rubioidae. It is a tree of varying size with a dark bark, shiny leaves, and orange oval fruit. A distinctive line of glands along the bottom of the central vein of each leaf connects this plant to the Hawaiian word for it, since piko means navel (in Hawaiian). The word kōpiko applies to all the Hawaiian plants in the genus Psychotria.

05DNA & barcoding4 specimens

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 Psychotria mariniana has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Psychotria mariniana carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.

Chromosomes & ploidyhow the DNA is packaged

2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants. Click any value below to see the underlying records and sources.

09Environmental DNA4 detections

Where the DNA of Psychotria mariniana 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 strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
