\Hy"brid*i`za*ble\, a.
Capable of forming a hybrid, or of being subjected to a
hybridizing process; capable of producing a hybrid by union
with another species or stock.
      Hybridizable genera are rarer than is generally
      supposed, even in gardens where they are so often
      operated upon, under circumstances most favorable to
      the production of hybrids.               --J. D.
