AB -An assessment of rare and threatened Pteridophytes of political India, classifying species into different categories, has been made based on our own field-observations, data from herbarium-collections, and published literature. Their general range in political India has been given, though only limited details of extra-Indian range are provided. Modern taxonomic concepts and nomenclature have been adopted. Our survey has revealed that 414 species of Pteridophytes (219 At risk, of which 160 Critically endangered, 82 Near-threatened and 113 Rare), constituting c. 41-43 % of the total number of c. 950-1000 Pteridophytes of political India, are threatened or rare there. 84 species included in earlier works are excluded as they are not considered to be of threatened status. One new combination and two nomina nova have been validated (Leptochilus pothifolius (D.Don) Fras.-Jenk., Asplenium rivulare Fras.-Jenk. and Thelypteris chandrae Fras.-Jenk.).
