Penstemon alluviorum, known by the common name lowland beardtongue, is a species of flowering plant in the veronica family. It is native to the Eastern United States where it is found in alluvial lowlands, particularly of the Mississippi and Ohio Rivers. Penstemon alluvoirum is a poorly understood taxon. The differences between this and two related species, Penstemon digitalis and Penstemon laevigatus, are not well resolved. It is identified within the complex by having corollas that are 15–23 mm long, sepals that are 3–6 mm long, and leaves that are 25–40 mm wide. It produces white (rarely lavender) flowers in May.Flora of the Southern and Mid-Atlantic States

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 digitalis has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
The complete instruction manual Penstemon digitalis 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.
Genome sizehow big the whole instruction manual is
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).
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.

Human sightings and records, or camera-trap / sensor detections — someone (or a device) saw or captured the species in the wild.

Where the DNA of Penstemon digitalis 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?
Modelled climatemodelled
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.
