Summary Gibbs, P.: The “Zavada hypothesis”: a rebuttal rebutted. ‐ Taxon 40: 583–595. 1991. ‐ISSN 0040‐0262. The Zavada hypothesis, that there is a correlation between the various types of self‐incompatibility mechanisms found in angiosperms and details of pollen exine sculpturing, is addressed again. In the light of a recent further defence of the hypothesis, some errors in the original data on which it was based are considered, and some criticisms by Zavada of a different data base are discussed.
