01Narrative

Asteridea nivea is a herb in the Asteraceae family, which is endemic to Western Australia. It was first described in 1845 by Joachim Steetz as Chrysodiscus niveus. In 1980, G. Kroner assigned it to the genus, Asteridea, giving it the name Asteridea nivea. It is a perennial herb, sometimes erect, sometimes low-spreading which grows on sandy soils often over granite, laterite, or limestone to heights from 10 cm to 60 cm, in rock crevices, on ridges and coastal cliffs. Its white to white-pink flowers may seen from April to May or August to September in Beard's South-West Province, that is, the IBRA regions of Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Mallee, and Warren.

05DNA & barcoding1 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 Asteridea nivea has left across the world's sequence archives.

09Environmental DNA1 detections

Where the DNA of Asteridea nivea 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.
