Incidentally I have Bailey, Manual of Cultivated plants (a standard reference  for cultivated plants) which treats Crinum asiaticum, C. amabile and C. augustum as three distinct species. Former is differentiated by white perianth and latter two by perianth red at least on outside. The author admits C. augustum as "doubtfully specifically distinct from A. amabile" differing in larger bulbs (up to 15 cm in diam.), less fragrant,  and broader perianth segments  (12-20 mm broad) as against smaller bulb, highly fragrant flowers and 10-12 mm broad segments. C. asiaticum is considered as a very variable species with bulb 10-13 cm in diam, flowers highly fragrant, white, with 10-12 mm broad segments. 
     Perhaps we should avoid consulting The Plant List for cases where better options like GRIN are available. The Plant List records all the three as distinct species, but interestingly considers A. amabile var. augustum (Roxb. ex Ker Gawl.) Ker Gawl. as synonym of C. asiaticum var. asiaticum,, but if you look at their source (World Checklist) the citation is C. augustum Roxb. (which The Plant List treats as independent species) as synonym of C. amabile. 
    It would be good to know whether our plants fits C. amabile or C. augustum on the basis of bulb size and perianth width, and wait for some recent publication which treats them better. GRIN considers C. amabile as synonym of C. asiaticum, whereas   Kew Worl Check List treats C. amabile as independant species with C. augustum as its synonym.

Sir,

Thank you very much for elaborating on three species of Crinum. Since i do not have bulb size and segment size i understand that this species should better be left as Crinum sp. only. Moreover i am not sure if this plant is fragrant or not, even if it is fragrant surely would be mildly.

Regards,

surajit
