Platonia insignis, the sole species of the genus Platonia, is a tree of the family Clusiaceae native to South America in the humid forests of Brazil, Paraguay, parts of Colombia and northeast to Guyana; specially in Amazon Rainforest. Common names include bacuri (and numerous variant spellings thereof; bacurí, bacury, bakuri, pacuri, pakuri, pakouri, packoeri, pakoeri), maniballi, naranjillo and bacurizeiro.
There was a degree of nomenclatural confusion, caused by Moronobea esculenta. If that were validly published for this species the current name would be Platonia esculenta. It was established that Moronobea esculenta is not a formal name (not "validly published"), so the name remains Platonia insignis.
In Julian Barbour's book The End of Time: The Next Revolution in Our Understanding of the Universe, Platonia is the name given to his hypothetic entity of a timeless realm containing every possible "Now" or momentary configuration of the universe.
The term can also be applied more generally to the "world of Forms" or "Plato's heaven" in Platonic metaphysics, and to the " ultimate ensemble" in Max Tegmark's variation of multiverse theory.

- Platonia, a plant genus in the family Clusiaceae

Usage examples of "platonia".
As time passes, the configuration of all particles in the universe is represented in Platonia as a moving point, so it traces out a path, just like a relativistic world-line.
Such apparently historical clouds in Platonia are called time capsules.
For exactly the same reason, a single fixed probability mist is not the only statistical structure with which Platonia can be endowed.
If Platonia is made into a Markov chain, each sequence of configurations gets its own probability.
So instead of single-state Platonia we get sequentialstate Markovia, where the universe makes transitions through whole sequences of configurations, and the most likely transitions are the ones that provide a coherent history - narrativium.
The result is to convert Platonia into what statisticians call a `Markov chain', which is just like the list of transition probabilities for snakes and ladders, but more general.
