Thanks, Rawat ji.

It's taxonomy seems quite confusing:

FOP gives Potentilla cuneifolia Bertol. with Potentilla ambigua Cambess. as synonym with the following remarks:

"Potentilla ambigua Cambess. (1844) non Gaud. (1828) is an illegitimate name because Potentilla cuneata was partly taken as a synonym of Potentilla ambigua which belongs to the genus Sibbaldia L. The proper name should be Potentilla cuneifolia Bert. (1863), that being the next valid name (cf. Sojak, 1969). The species resembles the genus Sibbaldia in the trifoliate leaves and shape and texture of the leaflets (broadly obovate, tridentate and coriaceous). It is, however, readily distinguished by its numerous carpels and stamens, large suborbicular petals, very long, filiform styles and densely sericeous achenes.

Chaoluan, Ikeda & Ohba (in Zhengyi & P. H. Raven, Fl. China 9: 296. 2003) have adopted Potentilla cuneata Wall. ex Lehm."

FON gives Potentilla cuneifolia Bertol., ; Misc. 24: 15, t. 2 (1863).= Potentilla cuneata Wall. ex Lehm.

FOC gives Potentilla cuneata Wallich ex Lehmann (syn: Potentilla ambigua Cambessèdes; P. dolichopogon H. Léveillé)

As per The Plant List, Potentilla cuneata Wall. ex Lehm. is a synonym of Sibbaldia parviflora Willd. & Potentilla cuneifolia Bertol. is an unresolved name (This name is unresolved, but some data suggest that it is synonymous with Sibbaldia cuneifolia (Bertol.) Paule & Soj k (Unresolved)).

Pl. clarify.

As per thread: Vof Week: Potentilla cuneifolia from Valley, Singh ji has clarified as below:

Our plant is Potentilla cuneifolia Bertol (not Potentilla cuneifolia (Rydb.) T.Wolf) an accepted name), which was described as Potentilla ambigua Camb. in Flora of British India.........The new correct name for this is Potentilla cuneata Wall.

Needless to say The Plant List seems to have bungled here also putting P. cuneifolia Bertol as synonym of Sibbaldia cuneata.

The correct name is Potentilla cuneata Wall. ex Lehm.:

Potentilla cuneata Wall. ex Lehm., ; Pugill. 3: 34 (1831).

syn: Potentilla cuneifolia Bertol. (non Rydb.) T.Wolf); P. ambigua Camb,

[D.S Rawat]

The remark by Dr G.Singh Sir clarify the things here. Rosaceae of India, a standard work on Indian Rosaceae by Dikshit & Panigrahi (Ros. India 4: 67, f.9. 1998) have accepted this name as the correct name. Pusalkar & Singh (2012) in their Flora of Gangotri National Park have also used this name.
In my view it should be taken as P. cuneata Wall. ex Lehm. as in FoNepal or if we follow Indian literature only as P.cuneifolia Bertol.
Sibbaldia genus is different from it and have 4 or 5 or 10 stamens only (our species has numerous as visible in the pics) and flowers are smaller (less than 1cm across) in Indian species.
Dr Singh understand nomenclatural complexities far more better than me and he has already explained it earlier as you have also mentioned.
