A reply:
"Yes, that's correct, it's Sphenomeris chinensis, or as I prefer,
Odontosoria chinensis (also molecularly cladonomised as Bierhorstia
chinensis, but not so much fitting in with the morphological taxonomy,
which I believe must also be considered!).
There is an apparently separate cytotype from South India, Lanka and parts
of SE Asia, described as O. tenuifolia, which is subtly different in having
rather wider segment-apices and slightly shorter segments - I think the
best treatment for that is as a subsp. tenuifolia as the two are so close,
but usually distinguishable, it seems. Subsp. tenuifolia is also turning up
now in N.E. India as well. Rather ironic that the entity named "tenuifolia"
is actually thicker and wider in its parts than chinensis proper - but no
matter. After all there's a Lathyrus japonicus that actually came from
Britain and does not occur in Japan at all, or E. Asia! - its locality told
to Linnaeus was a mistake - but it is still known as L. japonicus even so!
O. chinensis is very common at lower altitude through all the C. and E.
Himalaya and C. and S. India - but can't go very far west in the
Indo-Himalaya, not beyond Uttarakhand, I think (?memory!), as it gets too
dry for it at certain seasons. It is one of the commonest roadside weeds
around the Kathmandu valley, but try as you might, it seems you simply
cannot transplant it, or it immediately dies! Several ferns are like that,
also Palhinhaea ("Lycopodiella") cernua - that pretty clubmoss, would be so
nice to grow, but it will only grow where it wants to by spores - can't be
moved. Dipteris wallichii, though a common roadside weed in far NE India is
very hard to grow too. Both Odontosoria and Palhinhaea (and Dipteris to
some degree) grow in similar habitats on semi-open clay banks of paths and
roads.
