Abstract
A cladistic analysis of 22 morphological characters in 5 species ofMatricaria and 4 species and 2 subspecies ofMicrocephala shows thatMatricaria songarica, also known asCancrinia discoidea, is nested withinMicrocephala. It is consequently transferred to that genus and the new combinationMicrocephala discoidea is made. With this recircumscription,Matricaria andMicrocephala become much more clearly delimited and presumably monophyletic taxa.
