Juniperus macrocarpa Sm. ( Cupressaceae )

The distribution and origin of this species in the Pontine Islands deserve clarifications. Calbi et al. (2017) hypothesized a natural origin for this juniper recorded for

Ventotene. We observed the taxon in the same two localities (Cala Rossano, over Cala Bosco) and, additionally, in Via Parata Grande. Although the habitus and the growing habitats could support the thesis of Calbi et al. (2017), we learned from an inhabitant of the island that these junipers were planted about 30 years ago by an agronomist.
