Relationships of the ploidy levels in American elm.

Recent flow-cytometry research on Ulmus americana led to the surprising discovery that the species contains two ploidy levels, with diploids and tetraploids coexisting over the southern half of the species' range. Additional flow cytometry data has revealed additional stands where the two ploidy levels grow together; this seems to be a common pattern. Variation in microsatellite (SSR) markers suggest that the two ploidy levels are genetically distinct and have diverged significantly from one another.
