Western Sycamore

Platanus racemosa, Platanaceae

This is a 30- to 115-foot deciduous tree. Its bark peels off giving its trunk and main branches a puzzle-like appearance. The tree looks gnarled and it grows at seemingly odd angles. This is due to anthracnose (Gnomonia platani), a fungal infection. In years of cool, wet spring weather, trees can be completely defoliated by the disease.
