If you go along this ring-route, it will take you a few minutes to understand the origin of the place name "Bossea": as a matter of fact, this mountain is covered with a wonderful boxwood, a shrub formation dominated by the Common Box (Buxus sempervirens), which is very rare in nature. The Common Box is a "Tertiary relict", that is a plant which was very widespread in the Tertiary period thanks to the presence of higher temperatures and which could survive here thanks to favorable climatic conditions. Also the area substratum favored its diffusion: ophiolites, rocks with very particular mineralogical features (rich in heavy metals, toxic for most of the vegetation) have given the Common Box the possibility to grow "undisturbed" from the other plants, which cannot survive in the hostile environment.
