Mucajá palm (Acrocomia aculeata)

This week I had a note from a reader, who reported that he didn't get a very good germination rate from the Acrocomia palm seeds he brought back from Haiti. His comment prompted me to have another look at my own palms, in this case mucajá (Acrocomia aculeata) palms. I had visions of seeds germinating all over the place, but to my surprise, there were few. In the attached image you can see the ground covered with fruit. Not one had germinated and there were no young plants from previous fruit production. Next image, please.
