Hi Jim and Dash, Thanks for the additional information. > Ismene narcissiflora, I. longipetala, I. amancaes, I. hawkesii are the ones > I can recall offhand. I had noticed my narcissiflora (from you Dash) has the collar around the leaves at ground level, described by Alberto as indicating the difference between Ismene and Hymenocallis. Cheers, Rob
