Garg <[email protected]> No, that's not D. dilatatum, but D. latifolium. I think your identification references are a little out of date! Reports of D. dilatatum from South India are misidentifications for D. latifolium, which latter occurs in both the N.E. and south of India. I have not yet seen any correct collections of D. dilatatum from South India in any herbarium, or from my own collections, though I've seen many misidentifications as it. As I published in Indian Checklist 2, it is almost certainly absent from South India. Note the long, long sori, and the rather separate rectangular lobes of the pinnae - of D. latifolium, and texture of lamina more succulent.. However, the specimen is not a good example - as for all Diplazium we need to see the scales at the stipe-base. If this is not carefully preserved on the sheet (without rubbing the scales off), the specimen is inadequate - and may be unidentifiable in the case of other more difficult species of Diplazium and some other genera. D. dilatatum has many very narrow, almost fibril-like, brown scales running up from the stipe-base to half-way up the stipe, getting smaller and almost absent further up the stipe. But D. latifolium has few, short, broad, very black, crinkly scales confined to the stipe-base, the stipe-base usually being papillate at the very base, which is more easily visible in living plants. Both have very thick ascendent rhizomes, but both can give rise to thin, long-creeping runners with small plants with less dissect, but sometimes fertile fronds at their apices - especially in D. dilatata.
