Unknown Plant With Fruit and Flowers Growing in Shade - Please Help Identify?

This plant/tree has been growing under my trampoline for a few months. At first all the fruit was green and there were no flowers. Now the fruit is turning yellow and there are tiny white flowers with yellow centers.





Some people have already suggested guava, kiwi, and coffee. I don't think it's any of those, though. Another person thought it may be in the moraceae family, but I don't think that's the case either. It seems too peppery and tropical.





It's most definitely not a Brazilian pepper tree. I've had many of those, and this is extremely different.





Here is a link to some pictures:

It's an Amatillo plant, it's a type of weed that grows in ppl's gardens. Please don't eat the fruit, it's poisonous.





Here's a pic of it:

Reply:Looks like guavea but i think i could be wrong. You can take a sample and a few pics into any lowes or plant nursery and they will beable to tell you what type of plant that is.
Reply:I know EXACTLY what that plant is.. I don't necessarily know what it's called in English.. but most people call it "Philippine Lime / Lemon"





Where I'm from we call it "CALAMANSI" We have tons of that in the Philippines and that's what our lemons our.. it's more tart than lemons here in US.





I'm already here in California.. and we also have that in our backyard..





the weird thing is that it turns yellow here as it grows.. but in the Philippines it stays green..





you could make it as a juice (if you're not too lazy to squeeze about 15 to 20 of those just to make a glass).. but you have to add water and sugar.. and lots of ice.. it's good to drink specially on hot summer days.. it's really refreshing..





In the Philippines we also use it to put in our meals. I would love to tell you what they are but you might not be familiar with them.





If you have Filipino friends or if you just know anybody from the Philippines.. show them that fruit and they will tell you the same thing that I just said.








k.. that should answer your question.. =)
