American basswood (Tilia americana, Tiliaceae) is recognizable from a distance thanks to the interesting pattern of the leaves overhead. The large, thin leaves allow some sunlight to pass through them, and variable leaf density presents the unique mottled appearance shown above. Each individual leaf is several inches across and heart-shaped:
As I’ve mentioned before, basswood is commonly attacked by the basswood leaf mining beetle (Coleoptera: Chrysomelidae: Baliosus nervosus). Despite this pest, basswood flourishes across moist lowlands in eastern North America (Kershner et al. 2008). Since it’s relatively light and soft and easy to carve, it has some commercial use. I’ve most often seen it used for low-end solid-body guitars.
