I'm afraid that even before we start to deal with the ambiguities
your question is not clear.   What do you want to know, and before
you sat down at the computer what statistical test did you intend
to use?  (For better or worse, most of the documentation of R
_assumes_ you know what you want to test and how you want to
do it.)   I'm supposing you want to do some kind of comparison
across communities (tables 1 and 2), but I don't know what kind.
Comparing a single cell of the table to another just asks if
the leaf form is the same in the two communities.  Do you just
want to ask if leaf forms of a given species are significantly different
in different communities?  I'm not sure what the null hypothesis
would be here.  What are the rows and columns?  Can we use
them to develop a hypothesis?

If you can say precisely what your question is and how you would
test it in the _absence_ of ambiguity (i.e., specify a statistical test --
you don't need to know how to run it in R, that's what the list is
actually for), then we can help you decide how to handle the
multiple coding problem.

  good luck
