Taxonomic novelties and changes to Indian Pteridophytes are given briefly here in taxonomic order according to the forthcoming Annotated Checklist of Indian Pteridophytes vol. 3, nearing completion for Summer 2020. We have divided it into two parts, the present first part is from the main text re Families treated in vol. 3, the second part will be from the Appendix of corrections and additions to the previous volumes. Further details of the taxa and references will be given in vol. 3.

Taxonomic novelties and corrections to Indian Pteridophytes are given briefly here in taxonomic order according to the forthcoming Annotated Checklist of Indian Pteridophytes vol. 3, nearing completion for January 2021. We have divided it into two parts, the present second part is from the Appendix re corrections and additions to Families treated in vols. 1-2, especially concerning relevant publications that appeared subsequently to the two volumes. Further details of the taxa and references are given in vol. 3.

Following many years of detailed research in the field and in all relevant herbaria a comprehensive annotated checklist of pteridophytes of the Indian State of Arunachal Pradesh has been prepared listing all specimens we have seen and verified. As this work is now nearly complete, but will still take some time to enter new collections made over the last 3 years or so, we present here for the first time a simple list of all the species and subspecies we have verified from Arunachal Pradesh in advance of our main paper. Full details of the taxa, synonymy and range are given in The Annotated Checklist of Indian Pteridophytes vols. 1-3 (Fraser-Jenkins et al., 2016-2020). It is emphasised that the presence of a species has been indicated only after having seen and listed collections examined and re-identified by CRFJ.

We outline the phytogeographical relations of Turkish pteridophytes following revision of our previous check-list. Although mainly European, the Turkish fern-flora has c. 40% of its species and subspecies in common with or related to the West Himalayan European phytogeographical element. In the pteridophyte accounts of the recent Illustrated Flora of Turkey, it is clear that many specimens have been misidentified and various species incorrectly illustrated. In addition the extensive Turkish pteridophyte collections in international herbaria made by non-Turkish collectors, including those of the present first author, were not drawn upon and international consultation was intentionally not entered into. Although it is unfortunately not possible in the present circumstances to study and re-identify the great bulk of authentic specimens in Turkish herbaria cited in the Flora, we have reassessed some important records and corrected the many obvious anomalies in the Flora and we have added to the distributional data from our own critically studied collections. We therefore present an updated and taxonomically revised checklist with notes and additional distributions, including a few taxa overlooked in the Flora. We also treat the important subspecies which were omitted there. A new hybrid Asplenium and another of Cystopteris are described and a few necessary new combinations are made.
