Pinus wallichiana (Pinaceae), Bhutan Pine 165/026
This one’s named after Dr. Nathaniel Wallich (1786-1854), who was born in Copenhagen but who spent much of his life exploring the botany of northern India and nearby areas. Wallich was among the most prominent botanists of his times. He introduced the seeds of this pine into England in 1827. The tree is native to the Himalaya, Karakoram and Hindu Kush mountains, from eastern Afghanistan east across northern Pakistan and India to Yunnan in southwest China. It grows in mountain valleys at altitudes of 1800-4300m (but rarely as low as 1200m), and reaches from 30-50m in height. It likes a temperate climate with dry winters and wet summers.
Our three photographs of living trees are of specimens in Sackville Gardens in the city centre and one in a churchyard in Chorlton, Manchester.
