OK, I bought myself this a couple of days ago and got around to looking at it just now. Turns out the first plant I want to identify appears to be right at the front of the book on the "How To Use This Book" page ... which would make it Choisya ternata and the second could well be C. ternata Sundance. Still hunting for the 3rd plant!
I'll post pics @ the weekend anyway as it's always nice to get a second opinion.
