A few years back I asked about identifying a citrus rootstock (the lemon
above the graft had died) and was told that a picture of the flower was
needed.

At the moment it is showing flower buds. Is there anyone about who could
identify the rootstock once the flower opens?


See https://en.wikipedia.org/wiki/Citrus_rootstock

I have a number of citrus trees but doubt it will be any of those used
as a rootstock.
