Locally known as Trinidad Brazil nut, they are in fact related to the conventional Brazil nut as they all belong to the lecythis family (Lecythidaceae) which also includes the cannonball tree (Couroupita guianensis). The pod-like capsule is heavy and solid rather like a custom made pot and it has a detachable cover which pops off when the nuts are ready. In our case we had to give it a little help and gently prised it open after about a week. 
Inside the large "pot" are a series of nuts that line the sides of the pod. Each nut is nestled in place, stacked companionably against its neighbour. 
Every nut is attached to an fatty appendage that is likely to provide sustenance once the seed has germinated.
Apparently monkeys are very fond of this nut and are known to reach in and remove the nuts which are similar to Brazil nuts. Hence the name "monkey pot". It is also known as paradise nut.
When a nut was peeled, this is what it looked like. We all tasted it, assuming that if the monkeys ate it without harm, we should be safe. It was quite bland and oily and not as "nutty" and crisp as the conventional Brazil nut. I'm not sure that I would eat it again because after running a search through Google, there seemed to be some data showing the potential for selenium poisoning. Hmmm. We are alive to tell the tale but I would not recommend randomly eating this nut without further research. But it is a fascinating pod to see. The way the nuts are packaged in this pod (complete with lid) is wonderful. I would really like to see the forest tree that grows these pods. I can only imagine that it would have to be enormous to support the weight of its extraordinary crop.
