Garg <[email protected]> Er, I think you mean Underside!! Back side is usually used to refer to the human lower posterior - don't mind me saying! But actually this is such an abundant, widespread and well known species, no further image is needed. It is Pityrogramma calomelanos, which is an adventive S. and C. American species that spread around the world since the late 19th Century. It first appeared in Sri Lanka before spreading to India. Then spread to even the most remote corners of India like Ladakh, even! It spreads along paths and it may well be that the spores are carried along on the clothes of passers-bye, as a weedy invasive species. The other adventive Pityrogramma in South India (not yet in the north) is Pityrogramma austroamericana, which has slightly shorter fronds and subtly different pinna-segments - and bright yellow farina beneath, not white. In the 1950s they used to be cultivated in many heated greenhouses in Europe etc. as Silver and Gold ferns, that come up spontaneously from spores on old brickwork. Nowadays few can afford to heat greenhouses, anyway. Chris Fraser-Jenkins, Portugal. On Friday, 1 October 2021, 17:25:51 BST, J.M.
