though I've been back to Kew a number of times since Anne located the source of 4631 and 4632 (the Useful rather than the Ornamental Registrations), have to say that I've not made an effort to inspect these two and take photos - so the answer is that I've nothing to show for either at the moment.
When I next visit Kew I will order up the papers for them, and take some snaps which I will post in due course - though probably not for a month or so.
Have to say I don't really understand the reasoning behind the separation of Useful from Ornamental in the sense of these particular Registrations, but no doubt at the time it was considered necessary.
