But here I think we are perhaps caught up in a misunderstanding of the
hierarchy - rank has no absolute meaning.  Indeed, when Robert Brown
described families in Malvales, he compared them to tribes in Rosaceae - he
knew they weren't equivalent.  Many Malvales in the old sense look
remarkably similar, and in sight ientification one can get there very
easily - for the "families", even with flowers, it was much more difficult
(the Malvaceae in the old sense are parly an exception).
