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.
