thanks Maggi, you are a life saver (of Alstroemerias)..I couldn't find the index online.
I'm still trying to track volume down, I do have it here presumably but I'm sure there was something more recent than that. My memory isn't that good!
I've found it. The bonus is there is an article on Gesneriads too. Amazing, I can't work out if I have a great memory because it's an article from 13 years ago, or a really bad one because I thought it was only about 3 years ago.
Once again, Maggi, saves the day!
