This pot or pitcher shaped fruit was seen at botanical garden inside Karnataka University campus. The fruit is nonedible, probably even birds or animals don't eat it.
The fruit has a thick skin. On drying it becomes a shell.
We had a Parijata tree in our garden at Bhadravati home ...simple peaceful looking flower with a mild fragrance. The pictures below are shot at Prof. A R Desai's house at Dharwad.
A memorial to soldiers from North Karnataka who laid down their lives defending India.
If you want to see it and ask for the location, many people may not be able to tell. It's right opposite Dharwad DC Office gate, near Sub Registrar's Office.
