Pinus cembra subsp. sibirica

Pinus cembra subsp. sibirica - Siberian (stone) pine

The Arolla pine (P. cembra) is divided into two subspecies, the Swiss stone pine (P. cembra subsp. cembra) of the central and eastern European mountains, and the Siberian pine (P. cembra subsp. sibirica), which grows over a large range in Siberia, east of the Urals. These subspecies are separated by thousands of kilometres, but to the eye they differ only in the slightly longer cones and the shininess of the buds of the Siberian.
