I picked up these andiroba seeds (Carapa guianensis) in Belterra a few days ago and they've since been planted at Bosque Santa Lucia. As you can see, they're really very large seeds. If planted right away, they germination rate is very good. There are a few of these trees at Bosque Santa Lucia, one already producing seeds. The family is Meliaceae, the same as mahogany.
