Does a mature seed therefore have no milk?  I have heard that the endosperm
solidifies and always wondered why/how a liquid which would settle to the
bottom coats the inside so uniformly.  So, all the meat in a coconut is
solid endosperm?  Why the big hollow space?  To make it float?  Where is
the cotyledon?  Is there a scutellum-like structure  on the embryo?  What
fruit type would a coconut fall under? (not being a true nut).

Guess I was luckier than I relalized getting a supermarket coconut to
