An English Walnut tree (Juglans regia) on Melville Avenue near Westmount Park School.
From Wikipedia:
“In the Chinese language, the edible, cultivated walnut is called 胡桃 (hú táo in Mandarin), which means literally “Hu peach”, suggesting the ancient Chinese associated the introduction of the tree into East Asia with the Hu barbarians of the regions north and northwest of China.
In Mexico, it is called nogal de Castilla, suggesting the Mexicans associated the introduction of the tree into Mexico with Spaniards from Castile (as opposed to the black walnuts native of America).”
