Saxifraga hirculus L. Syn: Saxifraga prorepens Fisch. ex Sternb


Most likely it is Saxifraga prorepens (=S. hirculus var. alpina).


This looks like a compact form of Saxifraga hirculus to me, why are you thinking it’s not S.hirculus.


In broad sense, it is S. hirculus only. However, it has at least three varieties in NW Himalaya. Dvorsky et al in Flora of Ladakh have described variety alpina under S. prorepens Fisch. ex Sternb.


in my opinion this plant belongs to the group of Saxifraga hirculus s. lat., though I am not sure if this name is applicable to W Himalayan populations. Synonyms could be either Saxifraga hirculus var. alpina, or maybe Saxifraga prorepens. But on the whole I am afraid it is not satisfactorily resolved yet.
