Amphigamy
Definition
A mode of reproduction characteristic of cryptogamous plants, defined by the absence of obvious floral organs and the occurrence of fertilization through the union of simple gametes or hidden spores; also, in an extended biological sense, it can designate the symmetrical cellular fusion or direct hybridization between two genetic lines without macro-structural sexual differentiation.
