Elephantopus nudatus, common name smooth elephantsfoot, is a North American species of flowering plant in the sunflower family. It is native to the southeastern United States from eastern Texas to Delaware.Biota of North America Program 2014 county distribution map Elephantopus nudatus is a perennial herb up to 110 cm (44 inches) tall. Leaves are oblanceolate to spatulate, up to 20 cm (8 inches) long, darker on the upper side than they are on the lower side. The plant produces numerous small flower heads in a tight cluster, each head generally containing only 4-5 florets.Flora of North America, Elephantopus nudatus A. Gray, Proc. Amer. Acad. Arts. 15: 47. 1880.Gray, Asa. 1879. Elephantopus nudatus A. Gray diagnosis in Latin, description and commentary in English

The complete instruction manualElephantopus nudatus 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.

09Environmental DNA1 detections
Where the DNA of Elephantopus nudatus 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.
