Abstract: 1 figure. [Discussion of sibling speciation in lichens and how chemical variation patterns in lichens may be interpreted as examples of sibling speciation. "For the lichens, examples are given of sympatric sibling speciation effected by the isolating mechanisms of a sharply telescoped environment, the bark of different trees growing together, tree bark and nearby boulders and adjacent soils of different types. An experimental approach in the lichens for determining the extent of gene flow in morphologically similar populations of mixed chemotypes is proposed."]
