Observations

Representative specimens have been collected at the Cueva del Aura on Sierra Maestra, and on Pico Turquino (20° N, 17°50' W) at 1600-1700 m elevation on the steep rocks of Loma Regiona (the Pico's north spur) and on the summit of the Pico (Adams 1995).

Remarks

In Juniperus section Sabina, only young (up to 4 or 5 years) junipers have needle- or awn-shaped decurrent leaves. Scale-like leaves are then produced as the only adult foliage, except that juvenile foliage may occasionally appear at branch tips or in response to damage. There are two species that constitute exceptions to this rule: J. sabina (var. davurica) and J. squamata in the eastern hemisphere, and J. saxicola in the western (Adams 1995).
