ABSTRACT
Recent discovery of a low shrub from Topia, in the state of
Durango, Mexico that appears similar to both J. durangensis and J.
jaliscana, prompted the analyses of nrDNA and petN-psbM (cpDNA)
SNPs. The plants from Topia differed from J. durangensis by 2 indels
but were shown to be closely related as shown in a minimum spanning
network. Phytologia 91(2): 353-358 (August, 2009).
KEY WORDS: Juniperus durangensis, J. monticola, J. martinezii, J.
flaccida, nrDNA, petN-psbM, SNPs, Cupressaceae, geographic variation.
Juniperus durangensis Mart. is a tree or large shrub to 5 m that
generally branches near the base (Adams, 2008). It is often found on
rhyolite, a nutrient poor rocky volcanic substrate, in the mountains of
western Mexico from Sonora and Chihuahua southward to
