[Taxacom] early extant angiosperms

[Kenneth Kinman]

Dear All,
        I've been reading some recent papers on early angiosperms
(especially their floral evolution).  There is frequent (but informal)
reference to what I formally refer to as Class Magnoliopsida (basal
dicots).  Some workers tend to refer to this paraphyletic group as
"early-divergent extant angiosperms", while other (like Endress) seem to
prefer calling them "basal angiosperms".  But not surprisingly they are
not inclined to attach a formal taxon to this paraphyletic grouping, no
matter how important and useful they obviously find it.
       Anyway, I'm quite happy to continue formally recognizing this
group as Class Magnoliopsida, but I wonder which of the common names
would be preferable.  We are all referring to extant forms, so I don't
feel a great need to include that particular detail, but otherwise,
which of the follow three would be preferable as a common name of my
Class Magnoliopsida: (1) basal dicots; (2) basal angiosperms; or (3)
early-divergent angiosperms.  Here is the relevant part of my 2009
classification as a reference:

          PHYLUM MAGNOLIOPHYTA 

  1 Class Magnoliopsida%% (basal dicots)         
            1 Amborellales 
            2 Hydatellales (incl. Archaefructaceae)
              B Nymphaeales 
            3 Austrobaileyales 
            4 {{Liliopsida}} (= monocots)      
            B Ceratophyllales 
            C {{Rosopsida}} (= eudicots)
            5 Chloranthales 
            6 Piperales
            B Canellales
            7 Laurales
            8 Magnoliales 

_a_ Class Liliopsida (monocots) 

_b_ Class Rosopsida (eudicots)
