ABSTRACT
Analyses of nrDNA and trnC-trnD sequence data revealed that
the shrubby alpine juniper from Cerro Potosi is not allied with J.
monticola f. compacta from Ixtaccihuatl in the trans-volcanic belt of
central Mexico, but forms a distinct clade with J. saltillensis. Research
using Single Nucleotide Polymorphisms (SNPs) with samples of J.
monticola f. compacta from the near the type locality confirmed that
the Cerro Potosi alpine-subalpine juniper is not related to either J.
monticola f. monticola nor J. m. f. compacta. A new species is
proposed, Juniperus zanonii R.P. Adams, sp. nov. from Cerro Potosi
