An evolutional tree of human influenza viruses of the H3N2-subtype is suggested on the basis of combined published primary structures of the hemagglutinin HA1-subunit. Possible differences between natural and sequenced structures are discussed. A tendency to reversions in the course of antigenic draft within the subtype has been revealed to support the hypothesis of limited antigenic evolution within a single subtype.
