5.—Additional Cytotaxonomic Notes on the Pteridophytes of Jamaica

Abstract

Synopsis Cytological results are presented for 60 taxa of Jamaican ferns which supplement information obtained from an earlier survey (Walker 1966). A number of hybrids which form local populations and which may be mistaken for fertile species are described and illustrated. Some species complexes are examined and shown to be more extensive than previously thought. The results presented here are examined in the light of the findings of the earlier survey.
