It is native to Northern Mexico, the Southwestern United States (from southwestern Oregon and California east to Kansas and western Texas).Kew World Checklist of Selected Plant FamiliesBiota of North America Program, 2013 county distribution mapEspejo Serna, A. & López-Ferrari, A.R. (1997). Las Monocotiledóneas Mexicanas una Sinopsis Florística 5: 1-98. Consejo Nacional de la Flora de México, México D.F.. It grows in moist and sandy habitats with fresh to brackish water.

06Genome at a glanceCCDB
The complete instruction manualEleocharis parishii 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 Eleocharis parishii 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.
