are treated as tentative alternatives that may or may not prove to be correct in time - they
are alluded to at the end for Indian workers to bear in mind and make their own decisions
on utilising their experience and knowledge of the genera concerned. The geographical area
covered is: further east Afghanistan, Pakistan, India, Andaman & Nicobar Islands, Nepal,
Sikkim, Bhutan, Bangladesh and Sri Lanka. The author is currently working on updating
pteridophyte lists for Myanmar and Tibet. Adventive species are excluded, except for the
two very widely established species of Pityrogramma. Hybrids are excluded as of no floristic
importance. The number of species per genus is given in brackets, with an upper number
for species of uncertain status.
