Gurcharan ji Very nicely illustrated photographs of both the species. The easiest way to remember the difference in simple words. The corona highly elevated like a pyramid sometimes even above the petals.....*C.gigantea.* Petals high above the corona which is near bottom of the flower.......................*C. procera* Both the plants including the white variety are common in Pune.
