There is some difficulty on putting hull as synonym. I think there is a
precedence on creating a new term even though a part is called by
different name in a derive parent structure. e.g. in seed many parts are
derived from the ovule, e.g. chalaza, micropyle, testa etc. These are
derived structures or rather the same structures but sometimes can be
called by different names. Similarly it will be very difficult to
annotate phenotypes and gene expression such as in case of

to lemma and palea. In this case the actual structure is called as hull.
I think we need hull as a new term, and the parentage as follows
fruit
---part_of---hull
Also
floret
--part_of--lemma
-----develops_from--hull
--part_of--palea
-----develops_from--hull
