Myrciaria cauliflora fruits, or Jaboticaba.
 Myrciaria cauliflora (alternatively Plinia cauliflora; family Myrtaceae) is a small tropical tree with edible fruits, native to Brazil. Its species name is derived from the term "cauliflory," which describes trees which produce their flowers and fruits along their trunk and large branches, as opposed to at the ends of younger shoots. Cauliflory is mostly seen in tropical trees, although what function it might serve seems to be debatable. Possibly, flowers along trunks are more visible to pollinators (or fruits more accessible to animal dispersers) than they would be in the dense leafy canopy of the rainforest. There are no native cauliflorous trees in my area, but a little further south one shrub, the Redbud (Cercis canadensis), shows this condition to some extent.

Myrciaria in the UConn greenhouses, in about a 20 inch pot.
 Jaboticaba (sometimes spelled Jabuticaba) fruits are pretty tasty, with sweet, grape-flavored white pulp inside of rubbery, nearly black skins. The skins are a little bit tough, but also edible, with a slightly acrid flavor reminiscent of walnuts. In the greenhouse the flowers of Myrciaria self-pollinate, and set abundant fruit in spring without any special attention.
