EDITOR's REPLY: I fail to see how there could be any confusion if one reads 
the entire caption, which is only ten words long and states in full, 
"Erythronium revolutum with mottled leaves, E. dens-canis with spotted 
leaves." The author's distinction between "mottled" and "spotted" is 
clearly explained in the chapter, and one reason for using this photo was 
to illustrate that point. I doubt that those who read more than four words 
into the caption, and particularly those who read the text itself, will 
have to pen in a correction in their books.
