Paricá seed

There are several large paricá trees (Schizolobium sp) at Bosque Santa Lúcia and their seed production is quite prolific. There's only one seed in each pod and it's very hard after drying out. As a result, the germination of them can take awhile and the process can be spread out over long periods of time. I'm not totally sure of the species but I think it's parahyba.
