ness, to the broader view that, in outlining morphological change, we must 

 look upon — expect — simplicity in higher groups as at least as likely to be the 

 result of reduction as of the retention of ancient form, that simplicity may be 

 the result of parallel development. We must realize that resemblances may 

 have little morphological significance unless evidence is derived from several 

 fields of botanical study. I am reminded of a remark made by an assistant in 

 one of my morphology courses, ''This course should be called 'Things are 

 not always what they seem.' "
