Bitterwood Tree
Picrasma
A genus of deciduous trees and shrubs known for their extremely bitter bark and medicinal …
Occurring in the high-elevation montane forests of western China, this rare coniferous tree is distinguished by its adaptation to mountainous habitats. It grows in scattered populations, often occupying steep slopes and rocky cliffs at elevations between 2,000 and 3,400 meters.
This subspecies of Torreya fargesii remains relatively obscure and is primarily studied for its evolutionary divergence in leaf size. It forms part of the diverse coniferous understory in mixed temperate woodlands.
The tree can grow up to 15 to 20 meters in height, exhibiting a dark greyish-brown bark that becomes deeply fissured with age. Its crown is typically broad and rounded with spreading branches.
Key botanical features of this subspecies include the following:
The wood of the species is exceptionally dense, durable, and resistant to decay, making it historically sought after for high-quality carpentry and furniture. However, due to its rarity and protected status, commercial exploitation is highly restricted.
It also plays a role in ecological restoration and watershed protection in its native mountainous habitats.
