Mike, thanks for the names of the theobroma sp. I will see if I can find those in the collection at turrialba.
I wish I could be more precise on seasons of cupuasu and pataxte. Cupuasu is starting to flower right now. Both of these species will produce around Sept./Oct and there should be fruit right now but I have trouble getting cross pollination on cupuasu and it is hard to see the fruits, let alone the flowers on t. bicolor as the tree is pretty tall. Fortunately, the fruits fall when ready on both, unlike cacao.
We have new seedlings planted of both and I am trying to air-layer cupuasu, something that works for us with cacao. I intend to start grafting cupuasu as well.
