Mary, I don't think you've got a chance of getting a definitive answer to this one. There are accepted conventions but you and I would probably pronounce (and spell) the word 'tomato' differently and both be correct (cue for a song?). Ask any group of bulbophiles for the correct pronounciation of 'Nerine' and you will probably start a fight. The truth is that there are no latin-speaking Romans around to ask anymore so don't be put off by people who feel they have to correct you and do it your way. Leucocoryne normally has the accent on the first and third syllables but if somebody wants to correct me.....? Cheers. Den Wilson Isle of Wight UK.
