Horn Fruited Jute

Common throughout Pakistan in cultivated fields and wastelands on sandy alluvial moist soils, particularly after rains.

The young leaves and shoots are used as pot herb in India, Pakistan, tropical Africa and are sometimes dried for this purpose to be used in soup. It is commonly eaten by goats and camels. The stem yields a good fibre which is used in north Nigeria and elsewhere for fishing lines.
