The stone pine or arolla pine
Pinus cembra
Pines (Pinus sp.) are a genus of conifers that are widely distributed all over the world. Hundreds of species live in the temperate zone of the Northern hemisphere and in the subtropical belt of both hemispheres. This genus is characterized by fairly long needles that grow all around the shoot in bundles of two, three or five. The pine with the longest needles (18-22cm) is the American Pinus jeffreyi.
The regeneration techniques are also very interesting: most species drop their seeds when the strobili (= cones) mature; others, such as Pinus radiata, keep their cones intact for many years, until they open during a woodland fire and release their seeds. Pinus cembra seeds, however, are distributed by the nutcracker.
