The holly originated in the Tertiary period, when Italy did not yet have its present form.
This plant then survived successive ice ages and for this reason is considered a "relic of the Tertiary". Its botanical name is Ilex aquifolium, and it is generally thought of in connection with Christmas decorations.
In the Tertiary period, together with Taxus baccata, Daphne laureola and Eunonymus latifolium, it formed that facies of vegetation composed primarily of evergreens that today has almost completely disappeared from the Apennines.
In our valley it is still found in the hills and mountains, especially as undergrowth in the lower beech woods.
