" If Azima and Batis do exclusively clade together (in which case, there
should be a lot more synapomorphies than just the
secondarily-partitioned ovary; which what I am looking for),"
I am not aware that there is anything preordained about the number of
synapomorphies being required for any one clade. One is sufficient. Of
course it would only take one other character relationship to make that
problematic so it may be regarded as a 'weak' clade, but then again one
character may be all that there is.
