Pterocarya macroptera
Pterocarya macroptera, the large-winged wingnut, is a species of Pterocarya native to the temperate parts of China. It can be found in much of north-central, south-central, and southeast China and Tibet. On average, a tree grows to around 15-30 meters (49.2-98.4 ft). The species belongs to the section Platyptera within the genus Pterocarya, which also includes P. rhoifolia, P.insignis and P. delavayi. Some scientists consider P. insignis and P. delavayi to be varieties of Pterocarya macroptera. The species is vulnerable.
The species is commonly cultivated. It is hardy to USDA Zones 5–8. Some varieties are rather fast growing.
Pterocarya macroptera is a riparian and montane tree species that thrives in moist, temperate environments across central and southwestern China. It commonly grows along riverbanks, valley slopes, and mixed deciduous forests at elevations between 1,000 and 2,500 meters. Ecological and genomic studies indicate that P. macroptera shows strong local adaptation to temperature and humidity gradients. Populations are structured into three genetic lineages—the Qinling-Daba-Tianmu, Western Sichuan, and Northwest Yunnan groups—each adapted to distinct climatic conditions.
