I think the Pitanga do cerrado is a different botanical species with a dwarf habit and often a slightly different type of leaves. The one you have looks like Eugenia Uniflora to me, but I am not a botanist.
When you offer seeds for sale it is often helpful to say upfront how sure you are of the identification or wether you are just guessing. There are a lot of varieties of Eugenia Uniflora out there and they can be very different looking from one another. Some of them are reportedly very good!
