Hydrolea ovata is a species of flowering plant known by the common names ovate false fiddleleaf and blue waterleaf. It is native to the southeastern United States.Hydrolea ovata. USDA NRCS Plant Guide.Hydrolea ovata. NatureServe. This rhizomatous perennial herb has spiny stems growing up to 2 feet tall. The spiny, alternately arranged leaves are oval in shape. The flowers are blue. This is a wetland species. It grows near ponds, ditches, and other wet sites. It is used in wetland restoration projects. A colony of ''Hydrolea ovata''

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 ovata has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualHydrolea ovata 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.

09Environmental DNA2 detections
Where the DNA of Hydrolea ovata 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?
DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.
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.
