Physalis

Certainly sounds like physalis aka Cape Gooseberry. If it is, the berries are edible and make good jam.

The fruit in the picture doesn't look like a Physallis to me. It is fleshy and shiny rather than papery. In all the Physallis I am familiar with unripe bracts aren't fleshy.

acorn922 - can you give any more pictures? Perhaps one of the plant and its leaves?

The shape of the fruits is similar to Eugenia uniflora.

Yes it does look like Eugenia, I miss read the original discription, thinking this was inside the paper lantern. That will teach me to read slower.

I think you have it, Audrey. I've never seen that particular one but other species have the same waxy, plastic look.

Acorn922, if you need any more ids in the future, an indication of scale is always helpful.

As well as showing more of the plant than just a single part.

It's true the description "The seed inside is round like a large pea. " does not match the photo of a lumpy fruit.
A round, pea shaped yellow fruit inside a paper lantern is a Cape Gooseberry.
The photo provided is not.

Really looks to me like an immature Surinam cherry (eugenia uniflora), as stated above. We have them here.

Thank you for so many replies.
Turns out the mystery plant is a eugenia uniflora/Surinam cherry.

Didn't have my camera with me when I picked the berry. (Should've snapped off the branch to include some leaves for the photo.)
I planted some seeds last year and attached is a photo I took today of it's progress.

Now that I know it's edible, I'll have to try it.

Note to self: Remember scale!

Thanks again!
