Seed Viability of Monkey Ear Tree (Enterolobium cyclocarpum)

How long can monkey ear tree seeds (Costa Rica's state tree) remain dormant? I have an old ear pod—can I still use the seeds inside?

Seed Longevity Estimates

Most seeds viable 1+ years. Bean-like seeds (legumes) ~2 years if kept cool/dry. Pod protection may add a year. Beyond 2-3 years, viability drops sharply. Test by sowing a few—if they germinate, the rest are likely good. Enterolobium seeds are large and robust but not immortal.
