This is a very simple matter.

In my book it says that the pineapple is a hybrid. I am convinced it is a
very good book, but if there are two areas with a confused taxonomy then it
is monocots and cultivated plants. The pine-apple is both.

I have no need to establish anything. In response to a question about why
pine-apples have the properties they do have I pointed out that these
properties are the result of selection in cultivation and that the
pine-apple is regarded as a hybrid.

Anybody who wants more can do his own homework.
