ABSTRACT
The nrDNA sequence of the smooth leaf margined juniper of
the Serranias del Burro was compared with J. virginiana, J. scopulorum
and J. blancoi. nrDNA from S. del Burro was most similar to J.
virginiana and then to the J. blancoi/ scopulorum juniper from Colonia
Pacheco. The Serranias del Burro population differs by 3 SNPs in its
nrDNA from typical J. virginiana (central Texas) and appears to be a
Pleistocene relict . Phytologia 93(2):168-173 (August 1, 2011).
KEY WORDS: Juniperus virginiana, J. scopulorum, J. blancoi,
geographic variation, nrDNA, SNPs, Pleistocene refugia, Serranias del
Burro.
In a related study, Adams (2011) reported putative Juniperus
scopulorum Sarg. from Colonia Pacheco, Mexico was very divergent
