Dinesh ji, Thank you for the prompt reply. I went through the link. Leaves are very much alike but i think the following points vary in the photographs 1. the fruit is much more spiney than bitter luffa. 2. the flowers of bitter luffa are seen in clusterswhile the flowers of this plant are solitary. 3. The flowers are also raised on a long stalk almost 5cm long as seen in the images attached. I am attaching a few other images which i think may help Regards, Jui
