Thanks to Harry Hausman (and Mike)
I got to glimpse the tree and fruits in question at bender's grove. I'm quite certain that it's Garcinia acuminata, same species as pictured in whitman's book as charichuela, and Lorenzi's book, Brazilian fruits, as G. acuminata.
The trees which Mike at Benders has obtained are amazingly gorgeous, and truly inspiring to anyone who dreams of pushing the limits and fruiting this species outside of its preferred Zone...in a pot for me especially!! or a green house up in Canada or Colorado for some other members.
Have heard mixed reviews about this fruit, but generally the taste is amazing..but the seeds are large, and the sometimes scant amount delicious flesh is a tease to some who eat the fruit. One thing I can say, I've heard on several occasions that this fruit appeals to those who aren't interested in sampling rare fruits, or adventurous eaters so to speak...so I'm sure this fruit is amongst some of the better garcinia fruits that we can grow easily here in FL and possibly in containers and/or controlled climates...well out side of its native range!
O BTW...supposed to be everbearing!!?? that furthers the chances of inducing this jewel to produce fruits in colder climates, with less of a window for fruit development (unlike troublesome species; ex. mamey sapote
good luck with fruit development outside of the tropics).
Put me down for some scions...I'd love to tinker around with my cambium slicer and figure out what this species is compatible with. Also would be willing to pay about $8 to sample just one nice fruit!!! So Mike...if possible to purchase a fruit or two...let me know....we can discuss the details.
I hope my Identification is right...because it seems like G. acuminata is harder to obtain in FL ( or maybe USA in general...but I'm not sure why?).
Best of luck with your trees...I'm truly jealous of what a marvelous find those trees are...and wonder what grower would dare to sell those??? and what else may lurk in the shadows of some obscure FL growers collection........
