Well the lighting is superb - most flash pictures don't show things all
that well, against a dark background.
About teeth, dentate means tootherd, the sides of the tooth meet at an
acute apical pint, denticulate just small versions of dentation; aristate
are teeth which then have extended linear tips, like a spine; ciliate are
long narrow hair-like ptojections from the margin. Sometimes one gets
slightly intermediate states, but generally they are readily
distinguishable as different kinds of teeth etc.
A good, close photo of the undersice of a strobilus shouled show the cilia
or lack of them on megasporophylls and microsporophylls in these dimorphic
strobili - and whether ciliate at their bases etc.
Best,
Chris F.-J.

Sir,
Thank you for the id, and your appreciation (though I don't feel that I
really deserve it- I have a long way to go before I can take much better,
clearer photos that show the exact features needed for the id).
I have added a few photos of a tropophyll from various angles that might
show the exact features that you are looking for. (I am still trying to
search for the exact meaning of 'dentate' and 'ciliate' features of the
Macro and microsporophylls!)
PS- I am using a micro 4/3rd Olympus camera,with macro lens. The difference
comes from using a good flash diffuser.

What fantastic, superb photos! - best Selaginella photo I've seen anywhere,
clearly shows aristate median leaves and a very narrow pale margin to
leaves, plus of course the strongly dimorphic sporophylls (might need one
more of a strobilus from beneath to see cilia etc.?). How did you take the
photos and what camera? If only others could take such good photos of
Selaginella - you deserve a prize for excellent photographic service to
Pteridology!
My first impression is Selaginella chrysorrhizos. It is in that rather
ticky group, anyway. But tomorrow when I get more time I will study it
more carefully and see if I still think that. I did not know of S.
chrysorrhizos from Maharashtra, but it is in M.P. and in Kerala, so could
well (should!) be there.
Best wishes - I'm very impressed!
Chris F.-J.

Location: South-west Maharashtra, Western ghats.
Date: Jan end 2022
Habitat: Wet rocks near waterfall.
Habitus- growing laterally from rockface. Size 6cm.
I could not find any with strobili. Is it possible to id on leaf structure
and arrangement alone, considering the distribution ?
