01Narrative

Grindelia scabra, the rough gumweed, is a rare North American species of flowering plants in the family Asteraceae. It has been found in northern Mexico (Coahuila) and the southwestern United States (western Texas and southern New Mexico).Biota of North America Program 2014 county distribution mapNesom, G.L. 1990. Studies in the systematics of Mexican and Texan Grindelia (Asteraceae: Astereae. Phytologia 68(4): 303–332 distribution map on page 308 Grindelia scabra grows in dry rocky slopes and on top of mesas (flat-topped hills). It is an annual, biennial, or perennial herb up to 70 cm tall. The plant usually produces numerous flower heads in open flat-topped arrays. Each head has 17-30 ray flowers, surrounding a large number of tiny disc flowers.Flora of North America, Grindelia scabra Greene, 1898.

05DNA & barcoding1 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 Grindelia scabra has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Grindelia scabra 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 DNA1 detections

Where the DNA of Grindelia scabra 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.
