Thanks, Alan. I'm glad you spotted Lauw's question and answered it, since I didn't know either. Is there a book or website that lists all the currently accepted names for both Hymenocallis and Ismene? Not knowing where all these plants originate from, should H. x festalis and H. x 'Sulphur Queen' be labelled Ismene x festalis and I. x 'Sulphur Queen'? Also, I remembered I have a couple of seedlings of Hymenocallis amancaes. Is that now Ismene amancaes? ...Patiently waiting for Alan M., Kevin P., and their colleagues to write the definitive book on South American geophytes à la The Color Encyclopedia of Cape Bulbs by John Manning, Peter Goldblatt, Dee Snijman, ;-) --Lee Poulsen Pasadena area, California, USDA Zone 9-10 On Apr 23, 2004, at 4:11 AM, Alan Meerow wrote: > Lauw, > > Ismene: > Hymenocallis: > From: "Lauw de Jager" >> Dear Lee, >> I probably missed out somewhere.
