01Narrative

Pterostylis bicolor, commonly known as the black-tip greenhood, is a plant in the orchid family Orchidaceae and is endemic to south-eastern Australia. It has a rosette of leaves and when flowering, three to ten well-spaced, bright green flowers with a blunt, greenish-black appendage on the labellum. It is similar to the swan orchid, Pterostylis cycnocephala but that species has a beak-like appendage and crowded flowers.

05DNA & barcoding5 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 Pterostylis bicolor has left across the world's sequence archives.

09Environmental DNA5 detections

Where the DNA of Pterostylis bicolor 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.
