Copel. Wild fern from Western Ghats Tamilnadu.

I thought all would know that Paraleptochilus is a synonym of Leptochilus
as it has been published since Sledge (1957) onwards - so Leptochilus,
please.
However this is not L. decurrens (syn. variabilis), a bit narrow in both
fronds (though that is variable), and more importantly too smooth with
veins hardly visible. Sedge had a coarse concept when he combined L.
lanceolatus within L. decurrens, which we all followed previously. But
there is good evidence (incl. cytological) that lanceolatus is distinct -
and is in many ways intermediate between L. decurrens and L. thwaitesianus
and I have treated it so in the Annotated Checklist of Indian Pteridophytes
vol. 3.
In my opinion this can only be either L. lanceolatus or L.
thwaitesianus, not decurrens - a bit hard to say which from this photo.
But from its quite large size and the veins partly visible I'd think it
more likely to be L. lanceolatus than thwaitesianus.
