Initial reply from Dr. Chris:
" Yes, that's a fern OK. It is what many species of Lepisorus
do during the dry season. There are just two species in the south like
that, L. nudus and L. amaurolepidus - both common. In my opinion this is
almost surely L. amaurolepidus, because the fronds are rather close
together, whereas L. nudus has a longer rhizome with the fronds quite far
apart.
But you must confirm it by examining the rhizome with a X 10 lens,
looking against the light, L. amaurolepidus rhizome scales have a solid
dark-red basal central part, the rest being pale, quite wide - but those of
L. nudus are more or less uniformly greyish-brown.
Good searching!
One further question is about the status of L. amaurolepidus - it is
tetraploid and one count for L. contortus is also tetraploid (but we need
more counts and on more reliably identified specimens), both have fronds
that can be narrower or wider and the scales and soral position etc. atre
very similar indeed. I am not yet fully confident to say it, but it looks
to me that L. amaurolepidus may well be a synonym of L. contortus. I had
them both growing (have now lost amaurolepidus from S. India as last Winter
we had no water) and they looked identical in every detail.
Cheers,
Chris F.-J., Kathmandu."
