Penstemon hirsutus is a species of flowering plant in the plantain family known by the common name hairy beard-tongue.Dickinson, T.; Metsger, D.; Bull, J.; & Dickinson, R. (2004) ROM Field Guide to Wildflowers of Ontario. Toronto:Royal Ontario Museum, p. 332. It is native to the eastern Canada and the United States. This perennial species has hairy stems up to 90 centimetres tall, hence its species name, hirsutus. The leaves are opposite, stalkless, and lancelate. This species of Penstemon is found in dry alvars, prairies, savannas, and old fields.

Compounds documented for Penstemon hirsutus across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
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 Penstemon hirsutus has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualPenstemon hirsutus 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.

09Environmental DNA1 detections
Where the DNA of Penstemon hirsutus 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.
