Stachys floridana is a species of betony in the mint family, Lamiaceae. It is native to the United States, where its true native range is probably limited to Florida, but today it is known throughout the Southeast as an introduced species and common weed.Czarnota, M. and T. Murphy. Controlling Florida Betony in the Landscape. C 867-11. College of Agricultural and Environmental Sciences, University of Georgia. 2012. It occurs as far west as Texas, and it has been recorded in California.Weaver, R. Weed of the Month, February, 2010: Stachys floridana, Florida Betony, Rattlesnake Weed. Florida Department of Agriculture and Consumer Services, Division of Plant Industry. Its common names include Florida betony, Florida hedgenettle,Stachys floridana. USDA PLANTS. and rattlesnake weed. It has been called wild artichoke, but it is not closely related to artichoke.Burgess, C. Florida Betony. Home and Garden Information Center. Clemson University Cooperative Extension. 2005, revised 2008. The plant was the Florida Department of Agriculture's "Weed of the Month" for February 2010.

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 Stachys floridana has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualStachys floridana 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. Click any value below to see the underlying records and sources.

Where the DNA of Stachys floridana 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 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.
