Speaking of giant leaves, this is the leaf of a white/aurena I recently grafted whit some giant foliage! So if we are gonna describe by leaf size we might be in trouble! lol
it's a shame, but most people still rely on Julia Morton's book from 1987 (Fruits of Warm Climates) for info about Jabuticaba.
unfortunately she only wrote about 4 species, and had most of the facts twisted.
for instance, she identifies the "White" (or Branca) Jaboticaba as a form of M. cauliflora (but it's M. aureana)....and of course the biggest misnomer of all, she calls "Sabara", M. cauliflora as well (but it's M. jaboticaba).
you have to give her credit though, because she did a good job with the resources she had avaialble...just think how hard it would be to compile all the info she presented, without the advent of the internet.
(btw, that "super puffy large leaf" jabo u grafted is looking good!!!)
