01Narrative

Penstemon purpusii is an uncommon species of penstemon known by the common name Snow Mountain beardtongue. It is endemic to northern California, where it is known only from the Klamath Mountains and northern peaks of the North Coast Ranges. It grows in rocky open and forested mountain habitat. It is a perennial herb growing to a maximum height of 20 centimeters from a woody base. The leaves are 1 to 3 centimeters long, widely lance-shaped and sometimes folded lengthwise. The glandular inflorescence bears tubular flowers up to 3 centimeters long. They are generally purple-blue in color, often with white throats.

05DNA & barcodingmolecular

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 purpusii has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Penstemon purpusii 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.
