Penstemon barbatus, known by the common names golden-beard penstemon, and beardlip penstemon, is a flowering plant native to the western United States. In Spanish-speaking New Mexico and southern Colorado, it is called varita de San Jose "St. Joseph's staff".Dodson & Dunmire, 2007, Mountain Wildflowers of the Southern Rockies, UNM Press, The plant has spikes of clustered, tubular, scarlet blossoms with yellow hairs on their lower lip; the flowers are very attractive to hummingbirds. It is commonly grown in Xeriscape and conventional gardens, and several cultivars of different colors have been developed. The late-summer flowering of Penstemon barbatus coincides with the southern migration of the Rufous hummingbird, and the hummingbirds use the Scarlet buglers as "filling stations" for their long trip south.

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 barbatus has left across the world's sequence archives.

The complete instruction manualPenstemon barbatus 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
Genome size≈592 077 615 bp assembly estimate
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.

Sequencing statusassembly quality — how far to trust these numbers
Assembly level tells you how finished the sequence is — from fragmented contigs, through scaffolds, up to a full chromosome-level assembly. BUSCO % estimates completeness: the share of genes expected to be present that were actually found. These describe the data quality, not the organism.

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.
