The idea that Ashbery’s reference to “accents” in the poem’s last lines may have something to do with the nasal twang Ashbery felt he shared with O’Hara is tantalizing.  However, I think it’s unlikely that “Some Trees” is a love poem about O’Hara — not least because their relationship was, by all accounts, not a romantic one, but rather a close platonic friendship from beginning to end.  But who knows?  They were young and reckless and still in college at the time!  As I argue in the book, Ashbery spent a lot of time writing in subtle and oblique ways about his relationship with O’Hara, so I for one support this line of argument!
