Hydrophyllum appendiculatum, commonly known as the great waterleaf, is a species of plant in the borage family. It is native to the eastern United States where it is found primarily in the Midwest and Upper South. Its natural habitat is mesic calcareous forests. It is a biennial that produces lavender-colored flowers in late spring and early summer.Great Waterleaf at Illinois Wildflowers This species can be distinguished from Hydrophyllum canadense, which has a similar appearance and broad geographical overlap, by the presence of small appendages in the sinuses of the calyx. In addition, it has shorter stamens, which are only 1-3mm exerted from the corolla (as opposed to 3-6mm).

The complete instruction manualHydrophyllum appendiculatum 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.

Where the DNA of Hydrophyllum appendiculatum 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.
