section 'subdivisions' should be more than a list i hate to complain about a problem rather than just fix the problem but i really don't know enough about biology to be productive here the problem i read eudicots rosids and asterids although each article lists some representative species i the reader have no understanding what criteria was used to subdivide eudicots into rosids and asterids and others why is one plant a rosid but not an asterid these articles read as though plant life is subdivided arbitrarily though i suspect the subdivision is somewhat rational my intuition tells me that there must be some expressible meaningful distinction between these subgroups the proposal is there some way to describe the grouping here i propose a brief summary of the characteristics which divide rosids and asterids i think this summary should be a list of differences each difference taking this form rosids feature x in contrast asterids feature y thanks
