ABSTRACT
Analyses of sequence data from three nuclear genes and one
chloroplast gene region for Juniperus blancoi, J. b. var. huehuentensis, J.
mucronata, J. scopulorum and J. virginiana revealed that the J. blancoi -
huehuentensis - mucronata complex is closely allied but distinct from J.
scopulorum and very distinct from J. virginiana. The combined DNA
data support J. mucronata as a sibling species to J. blancoi or as a variety
of J. blancoi. Considerable differentiation was found in the J. blancoi
population from El Oro (Carmona) and additional sampling is needed to
resolve that variation. Phytologia 91(3): 571-580 (December, 2009).
KEY WORDS: Juniperus blancoi, J. b. var. huehuentensis, J. b. var.
