yes I agree as Physalis sp. The dimension (size) of the calyx may very due to  environmental factor. Molecular phylogenic study may help further.

Physalis sp. (Solanaceae)

Thank you!

Probably Physalis peruviana (http://en.wikipedia.org/wiki/Physalis_peruviana) or Physalis pubescens (http://en.wikipedia.org/wiki/Physalis_pubescens)

Hi This is Physalis alkekengi L.

Oh sorry

I think Physalis angulata is more correct.

Regards

looks like Physalis peruviana to me. I use to eat it when i was a little kid :)

Thanks you all for your help!

It may be Physalis minima L. 

Yes, certainly a Physalis for sure and likely Physalis angulata. More details in this book. Good luck!

Book Plants in Tropical Cities

Fruiting calyx should be up to 3.0 cm long - Physalis minima L.

Fruiting calyx should be more than 4.0 cm long  - Physalis peruviana L.

It may help for this species identification.

I think its Physalis pubescens.

Physalis angulata, most likely.

Most probably it is Physalis minima. Morphologically, You can easily identify the species through flora. But the morphological studies confirmed by molecular analysis gives best results. Look for the key to species.

It is Physalis minima of  family Solanaceae .Its fruit is having acresent calyx(persistent and completely cover the fruit)

It is a Physalis sp belonging to the Solanaceae Family.

Genus is physalis but not sure about species because not enough data for correctly identification. it is very difficult for it. you take more and more information about plant for its identity

Physalis minima Family solanaceae usually physalis and withania the fruit covered by calyx

@ Dr. Elisa Graña

Yes, this plant is Physalis peruviana L. of family Solanaceae.

Thanks!
