In October 1920, the Committee sent out a letter to as many botanists as could be located in India, inviting them to become Charter Member of the new Society.
It was agreed that 25 members would be considered sufficient for founding the Society and that office bearers should be elected when this number was reached.
The response to this invitation was so immediate and hearty that it was possible to hold elections for office bearers of the Society by about the middle of November.
Upon completion of the election on December 6, 1920 the Society was declared duly organised, and the Committee of organization ceased to exist.
