nrDNA and cpDNA were sequenced of J. ashei and J. ovata from populations throughout their ranges. No J. ashei populations were found to be pure in their nrDNA for every tree, however all J. ashei trees in every population contained only the pure J. ashei chloroplast type. Populations of J. ovata in trans-Pecos Texas were almost pure in both nrDNA and cp DNA. Several plants in the J. ashei range contained J. ovata-type nrDNA (White Cliffs, AR, 3/10); Ranger, TX (1/5); Waco, TX (1/12). Every J ashei population contained at least 1 plant with hybrid (heterozygous) nrDNA and 3 J. …
