01Narrative

Penstemon isophyllus, the equal-leaved penstemon, is a species of flowering plant in the plantain family Plantaginaceae, native to Mexico. It is a recipient of the Royal Horticultural Society's Award of Garden Merit. Growing to 70 cm, it is a woody evergreen perennial with reddish pink tubular flowers. Although hardy to -10 C, it benefits from some winter protection in colder areas. The Latin specific epithet isophyllus means "with leaves all of the same size".

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 Penstemon isophyllus has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Penstemon isophyllus 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 isophyllus 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.
