In the case of Capparidaceae I took the spelling from Watson and
Dallwitz's Oceanopapaveraceae page, and hadn't taken sufficient notice
of the family to notice the variation in spelling. (It's not a family I
come across very frequently.) Ah, well, a bit more editing to do. Ta.

Well, Capparidaceae has quite a following, but officially it is Capparaceae.
For relative frequencies see Google. Mostly I just wondered if it was
deliberate.
