Hello again
Here are my litle contribution for the discussions about this Psidium species whose fruits are known in Brazil as “Araçá-Una”.
There are many places online where you can find this Araçá-Una going by the scientific name Psidium eugeniaefolia.
Me too when I first received these seeds from Helton they arrived to me labelled as Psidium eugeniaefolia, and back then, by 2007 I think, I received another species labelled as Psidium myrtoides that some years later gave me fruits that were different from the regular Araçá-Una….
As I said many times before I’ve grown and fruited both those species (both seeds from Helton) but eventually eliminated them from my collection because those fruits were terribly acid and astringent, and almost unedible...
But some time ago, one fruit collector friend, told me he was growing a tasty variety of this Araçá-Una… I had to visit my friend during the fruiting season of his tree so to try this fruit for myself as I was a little bit sceptic after my first experience with this one… but fortunately it was true and my friend gave me one small tree that I have growing here at my place and it is also fruiting now!... YEEESSSS!!!!!
This Araçá-Una variety fruits are still on the acid side, but very tasty and enjoyable right from the tree…. and definitely much better than the previous ones I had.
After digging a litle deeper on the proper scientific ID of this Araçá-Una I decided to follow Mr. Harri Lorenzi that calls this species Psidium myrtoides (Pag.nº482 on the new book Frutas no Brasil).... Mr. Lorenzi doesn't use the name P. eugeniaefolia, not even as a synonimy.
Here some pics of my fruits:
