Ironically, the proposed phylogenetic code deals with reticulation better,
since there is not the requirement that the hierarchy be non-overlapping. A
species or lineage of hybrid origin can belong to two overlapping clades.

And "most cladists" certainly doesn't include students of angiosperm
phylogeny; dealing with reticulation is a common activity for many of us.
