Which tree native to Florida produces these seeds? The pods are really long and the seeds inside are in the shape of little hearts.
With pictures posted, it looks like it is the African tulip tree (Spathodea campanulata). The decisive features were the long pod with the pores. Similar (but not as strongly heart-shaped) seeds are seen in the jacaranda tree, which has a wider and rounder pod, which usually opens with an outer membrane attached to the edges.
