This species closely similar to C. circinalis but distinctly narrowed vegetative tip of megasporophyll without distinct teeth was earlier thought by me to be C. rumphii, but recent paper on Indian species of Cycas suggests that C. rumphii does not grow in India. Could it be C. indica or C. zeylanica.
