Thank you all for commenting on this. In the past, we have mostly
followed Jane's guidelines but the question about the Iris descriptions
got us thinking. My style book says to italicize non-English words, so
I have done that, even in common names. I have to admit that I have
accepted an author's styles when he/she seemed to have definite rules,
so we have been inconsistent about this in the Bulb Garden.
