01Narrative

Pterocymbium tinctorium is a tropical forest tree species in the family Malvaceae, subfamily Sterculioideae (previously placed in the Sterculiaceae). In Vietnam, it is known as dực nang nhuộm. In Indonesia, it is called kelumbuk, where it is a significant timber tree growing to about 25 m high. In the Philippines it is called malasapsap.

05DNA & barcoding2 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 Pterocymbium tinctorium has left across the world's sequence archives.

09Environmental DNA2 detections

Where the DNA of Pterocymbium tinctorium 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.
