This is what I found out about this tree: It is a very unusual tree native to Brazil whose fruits are formed directly on the trunk and branches. The grape tasting fruit has a thin astringent purplish black skin, with a sweet white fleshy pulp and can be eaten fresh or be used to make jellies and drinks (plain juice or wine).
Up to four times a year small yellow-white flowers followed by the fruit dramatically emerge directly from the trunks, limbs and large branches.
Traditionally, the sun-dried skins have been used as a treatment for asthma, diarrhea, and gargled for chronic inflammation of the tonsils. So now we know!
