Garg <[email protected]> No, sorry, it isd not at all Pteris quadriaurita, which is uncertainly known from India, but is in Sri Lanka. You can see the sinus between the pinna-lobes is not cut right down to the costa as it is in P. quadriaurita, and the pinna-lobes are not toothed as in quadriaurita. Sori in all Pteris are at the margins beneath. But for this group it is good you showed the top surface. As you can see there seems to be a pale central strip along each pinna (paler along the pinna-costa and lobe-bases, so I assume it is P. argyrea. The stripe is not very prominent so is a bit towards the P. confusa form of argyrea (I think both are conspecific). But that feature varies continuously from bright white to vaguer or to all green - it is not of taxonomic importance. Best wishes, Chris Fraser-Jenkins. On Monday, 13 April 2020, 12:35:52 WEST, J.M.
