Sir, Very interesting! here I'm pasting one more key, may it help you, I had never seen *Saxifraga diversifolia*, so don't have images of the same.
Basal leaves with truncate-cuneate base; style absent or reduced............. *S. diversifolia. * different shape of radical and cauline leaves. Basal leaves with cordate base; style present, conspicuous.......... *S. parnassifolia* *Thanks & Regards* Sunit Singh Research Scholar [image: Mailtrack] <https://mailtrack.io?utm_source=gmail&utm_medium=signature&utm_campaign=signaturevirality11&;> Sender notified by Mailtrack <https://mailtrack.io?utm_source=gmail&utm_medium=signature&utm_campaign=signaturevirality11&;> 04/12/22, 10:30:57 PM On Tue, Apr 12, 2022 at 2:48 PM J.M.
