Measurements of pollen tetrad diameters of eight ericad species from Burns Bog, Delta, B.C., showed that although diameters range continuously from 22 to 53 μm, groups of species can be recognized. These groups are ecologically significant with (i) small tetrads indicating dry habitats, (ii) intermediate tetrads indicating intermediate to dry sites, and (iii) large tetrads characteristic of wet habitat species. Pollen productivity of six of the above species varies, with those in dry sites producing much more pollen than species of wet habitats. Tetrad diameter spectra obtained from bog sediments under various ericad associations are dominated by tetrads of a diameter characteristically produced by the species growing at the site. Therefore fossil ericad assemblages can be interpreted on the basis of tetrad diameters.
