Garg <[email protected]> Not this time! Way off, I'm sorry to say. Cyathea (Gymnosphaera) gigantea is glabrous beneath the pinnae and does not have small hairs like that anywhere. Also those sori are not in Vs - when you see real C. gigantea you will see V-lines of sori, quite different. Also the lowest pair of opposite veinlets anastomose beneath the space between the pinnules - they are free in C. gigantea. This is Thelypteris (Christella) dentata agg. - I say agg., because in southern and W. peninsular India T. dentata includes two close species. True T. dentata has a rather short-creeping , thick rhizomes, closely surrounded by old stipe-bases, with fronds arising all together at its apex - and has a bit longer hairs beneath the pinna-costae. But the other taxaon, which is either T. malabarica or T. meeboldii (sorry I didn't finally see which) has a much longer and thin, creeping rhizome with fronds rather well apart, and the hairs beneath the pinna-costae are smaller. I vaguely guess your plant is the latter, but for Thelypteridaceae we need to know about the rhizome. I wonder if you photographed it? - Or included it in the herbarium-specimen? Incidentally, hoth C. gigantea and T. dentata are terrestrial, not lithophytic. Lithophytic means growing on the side of the rock, not on the ground. Having stones in the ground between soil does not mean they are lithophytes. Best wishes, Chris F.-J. On Monday, 24 January 2022, 04:29:39 GMT, J.M.
