Juglans sp. - Wild walnut

[luc]

John in PR , this is something for you .

I went to check on these in the jungle , found one tree ( huge ) with fruits all the way on the top . Not sure when they will be ripe , I guess they just fall on the ground when ripe .

They look like regular walnuts, with harder shell..here they are ripe when the outer green skin start to break and drying and then it fall to ground, then they should dry for some more time.. Also there is an liquere made from young fruits..


Here is one lost walnut I found this spring in garden sprouting..

Hi Luc

I had researched tropical walnuts in the past but settled on trying neotropica as it seemed to be the only one readily available. I decided to revisit the subject as a result of your post and came across an interesting document from over 50 yrs ago but it should still be helpful in determining what your mystery walnut is.  The download is here:

Those are Juglans Major nuts.Neotropica has red husks.

The nut resembles Japanese walnut Juglans ailantifolia.

The nuts can also be from a Junglans nigra tree...ist nuts have a pretty hard shake
