| 1922 G. Turesson in Hereditas III. 345 It seems appropriate..to denote the total sum of possible combinations in a genotype by the term coenospecies... I take the opportunity of thanking Mr. Otto R. Holmberg, Conservator of the Botanical Museum of Lund, for the coining of this term. 1939 Nature 11 Nov. 822/2 G. Tischler..stated that at least 400 wild cœnospecies of Angiosperms are known which contain races with chromosomal differences. 1957 Encycl. Brit. XXI. 177/1 Coenospecies. This term was first used by G. Turesson (1922) for the sum total of possible combinations of a genotype compound as seen particularly through cultivation under artificial conditions. The term has also been used to include groups of species separated only by extrinsic barriers to gene flow. |
