Juniperus communis
Some botanists treat subsp. "alpina" at the lower rank of variety, in which case the correct name is "Juniperus communis" var. "saxatilis" Pallas, though the name "Juniperus communis" var. "montana" is also occasionally cited; others, primarily in eastern Europe and Russia, sometimes treat it as a distinct species "J. sibirica" Burgsd. (syn. "J. nana" Willd., "J. alpina" S.F.Gray).
