Differences:
C. procera: Flower buds subglobose; corolla 1.5-2 cm across; lobes broadly ovate or ovate-triangular, 0.7-1 cm long; corona lobes equalling or exceeding gynostegium, straight on back above spur; apex bifid without auricles.
C. gigantea: Flower buds cylindrical; corolla 2.5-3.5 cm across; lobes long ovate or oblong, 1-1.5 cm long, reflexed; corona lobes shorter than gynostegium, curved on back above spur; apex rounded with two auricles.
 
Keys:
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
Flower buds like "modak" (during Ganesha festival, modaks are made) ............ C. gigantea
Flower buds like "pedha". (I am sure every one knows the shape of Pedha) ......C. procera..


Pl. go through ‎Calotropis page (Apocynaceae) with images of species in efloraofindia (done by Bhagyashri ji & TSP Kumar ji).
