01Narrative
Hydrolea quadrivalvis is a species of flowering plant in the family Hydroleaceae that is known by the common name of waterpod. It is native to the Southeastern United States, where it is found in the states of Louisiana, Mississippi, Alabama, Florida, Georgia, South Carolina, North Carolina, Virginia, and Tennessee.Biota of North America Program 2014 County Distribution Map It is also found in the state of Maryland as an introduced species. Hydrolea quadrivalvis is a perennial herbaceous plant which grows up to 6 decimeters tall. It has lanceolate leaves that range from 4 to 10 centimeters long and 10 to 25 millimeters wide, and most plants have stout thorns on nodes. It is an obligate wetland plant and often occurs in swamps and marshes Unlike its relatives, Hydrolea uniflora and Hydrolea palustris, Hydrolea quadrivalvis has sepals and stems with spreading, jointed hairs.

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 Hydrolea quadrivalvis has left across the world's sequence archives.

The complete instruction manualHydrolea quadrivalvis 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.
