Jabuticaba ?
         The Tree that Fruits on its Trunk

     No, this is not a belated April Fool?s prank. They look as if they may have been pinned there by an overenthusiastic gardener to impress the neighbors, but the fruit of the Jabuticaba really does grow off the trunk of the tree.
    Otherwise known as the Brazilian Grape Tree, this plant is native to South America, notably  Paraguay, Argentina and (obviously from its name) mostly from Brazil. The fruit, a succulent looking purple color, can be plucked and eaten straight from the tree. 
    It is also a popular ingredient in jellies and is also juiced to make a refreshing summer drink.  What is more, it can be fermented and made into wine and strong liquor. After three days off the tree the fermentation will begin, so sometimes, there is no choice; honestly. 
    If you want one of these in your garden, then you have to be patient. The tree takes an age to grow, but once it reaches maturity it is worth it. However, it has proven to be very adaptable and, although it prefers moist and slightly acid soils, it will even grow well in an alkaline type soil.
    The flowers themselves appear on the tree at most twice a year ? naturally. They look like some strange alien creature that has deposited itself on the trunk and branches. The habit of flowers doing this makes them cauliflorous. Instead of growing new shoots, these plants flower direct from the woody trunk or stem. 
    You might ask why it is this way. The simple answer is that it has evolved in this manner so that animals that cannot climb very high can reach it, eat it and then expel the seeds away from the parent tree to further propagate the species. 
    If the tree is well irrigated then it will flower and fruit all the year round.  The fruit itself is about four centimeters in diameter and has up to four large seeds.  As well as being used as food, the skins can be dried out and used to treat asthma and diarrhea. 
    If your tonsils are swollen you can also use it to try and alleviate the inflammation.  It is also hoped that the tree will be useful in the fight against cancer, as several anti-cancer compounds have been found in the fruit.

Well i GOOGLED it and the information seems to be true. Its known as Myrciaria cauliflora (Mart.) O.Berg

---

very interesting ... i think this belong to the family moraceae same as ficus infectoria or ficus glomerata 

---

Thanks a lot for sharing the pics and information. A nice piece of research it seems. Myrciaria cauliflora as the name suggests cauliflora means "flowering on the stem".

---

Appears to belong to the Flacourtia genus. May be Flacourtia jangomas

---

YES THIS IS  JABOTICABA... a cauliflori tree from Brazil... called Myriciaria cauliflora
I will send a new post with my pictures, from a botanical garden started by a physician in California...
I was not there when the tree flowered but have seen , photographed and tasted fruits of this tree elsewhere,
somewhat sweet..

MANY trees set flowers and fruits on its trunk directly.... some that come to mind right here are:
Cocoa or Theobroma cacao
Jackfruit or kathal  or Artocarpus heterophyllus
Calabash  or Crescentia cujete
Cannonball tree or Couroupita guianensis
Devphal or  Artocarpus gomezianus Wall. ex Trécul
   and this... Jaboticaba... or Myrciara cauliflora....
