1891 M. Hartog in Nature 17 Sept. 484 Isogamy, the union of gametes undistinguishable in size, form, and behaviour.
1935 F. E. Fritsch Struct. & Reprod. Algae I. 43 Isogamy (i.e. the fusion of morphologically identical gametes) is very usually..combined with an absence of differentiated organs for the production of the sexual cells or gametes.
1964 E. J. H. Corner Life of Plants vi. 85 The process is called isogamy or the union of outwardly similar gametes.

1891 M. Hartog in Nature 17 Sept. 484 True Parthenogenesis..may occur in the case of (1) Isogametes (2) Anisogametes (male and female); (3) Oogametes.
1935 F. E. Fritsch Struct. & Reprod. Algae I. 46 Isogametes are commonly positively phototactic.
1952 C. J. Alexopoulos Introd. Mycol. i. 17 We use the terms isogametangia and isogametes..to designate gametangia and gametes which are morphologically indistinguishable.
