01Narrative

Pterostylis aphylla, commonly known as the leafless greenhood, is a species of orchid endemic to Tasmania. As with similar greenhoods, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves flat on the ground but in this species, the flowering plants have a single green and white flower with a brown tip and lack leaves apart from a few small scales.

05DNA & barcoding2 eDNA hits

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 aphylla has left across the world's sequence archives.

09Environmental DNA2 detections

Where the DNA of Pterostylis aphylla 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.
