Had a really nice time black-lighting outside of Resaca De La Palma State Park. Conditions were pretty good -- although it was a bit windy later on.

douggoldman描述
This tree species is both cultivated and naturalized here. The first ten photos are of a cultivated individual, and the remaining nine photos are of young, naturalized individuals. The leaves in the fifth photo, of leaves side-by-side, were collected from a single 2-foot length of twig. Photos 11-12 are of a young tree that had fairly normal leaves, then got cut down and thereafter resprouted, making sharply lobed leaves typical for this species when regenerating from severe damage. Photos 13-17 are of saplings only a few years old.
The leaf shape variation is pretty extreme in this species.
