This is the ripe orange bumpy fruit. I was unable to identify it for a long time, just recently found it in a book called Fruits and Cultivated Exotics that I found at Fairchild Botanical Garden. The taste and texture are very interesting. Taste is tangy and slightly citrus-like. The texture is like that of unripe jackfruit only finer fibers, as a visitor to the site pointed out (see comments), similar to kiwi. I germinated a bunch of seed about five months ago. The small trees are just now about to surpass me in height. Supposedly the tree yields an excellent hardwood, said to be superior to Teak, useful for toolhandles and construction both above and below water. The trees I saw were not cultivated as a hardwood.
This photo was taken a month after transplanting the germinated seedlings, they are growing quickly. I'll take some up-to-date photos to upload today.
