Because priority applies to names of family rank (Art. 11.1).  I assume the
"type genus" of Betaceae is Beta, whivch I presume is included in the same
broad family as Chenopodium and Amaranthus, the "types" of the other two
family names.  This being the case, i.e., all three "type genera" being in
one family, the correct name of the family is the
earliest.  Circumscription per se has virtually nothing to do with
determining the name of a group; application of names is based on the type
