Dinesh ji To me your plant seems to be the same as one uploaded by Raman ji as Jacquemontia pentantha, and also commonly cultivated in Delhi. J. paniculata and J. coerulea seem to be quite distinct species. J paniculata has calyx lobes ovate-lanceolate nearly 5-6 mm broad, and corolla shorter barely 1 cm long as against 2-4 mm broad and corolla 2 cm long in J. pentantha. Plus if we see most photographs on net including one on Flowers of India (Garg ji), J. paniculata has lighter coloured (nearly white flowers with distinctly narrow and sharply pointed corolla lobes.
http://commons.wikimedia.org/wiki/File:Jacquemontia_paniculata_W_IMG_2931.jpg http://florabase.dec.wa.gov.au/browse/profile/6643 *Jacquemontia* *coerulea* (Schum. & Thonn.) Choisy ex G. Don is now considered as synonym of J. ovalifolia (Choisy) Hallier.f. seems also to have similar coloured flowers but with much broader corolla lobes and apparantly larger flowers and much different oval leaves.. http://eol.org/pages/580906/overview But there also seems to be confusion about the status of *Jacquemontia **violacea. Flora of China reports *Fang and Huang (Fl. Reipubl. Popularis Sin. 64(1): 46. 1979) incorrectly listed Jacquemontia violacea (Vahl) Choisy, based on * Convolvulus* *violaceus* Vahl, as a synonym for *J.* *paniculata*. * Jacquemontia* *violacea* is a synonym of *J.* *pentantha *(Jacquin) G. Don, a West Indian species introduced to Asia as an ornamental but not known to be in China. The Plant list only adds to the confusion. It treats it as synonym of * Jacquemontia* *paniculata* (Burm. f.) Hallier f.<http://www.theplantlist.org/tpl/record/tro-8502427>, but treats its basionym *Convolvulus* *violaceus* Vahl<http://www.theplantlist.org/tpl/record/tro-8500849> as synonym of Jacquemontia pentantha (Jacq.)
