I think Potentilla hudsonii

Both ternate and palmate on same plant.

Stem length > 10 cm

Petiole length 2 cm, 1.7 cm, 2.7 cm. Verrucose hairs.

Central leaflet length 1,7- 2,5 cm

Leaflet teeth per side mostly 4, some 3-6. Lenght >3 mm (sometimes secondary present)

Pedicel length less than 1 cm.

Incised to 3⁄4 or more to midvein. Adaxial surface with hairs common to dense.

@margaret_eaglecap
I called this one Salix arctica var. petraea (the var. on the advice of Salix expert I "knew" from Facebook, referring to some similar photos I posted if not necessarily the same ones). The flower bracts are very dark, greenish-black, suggesting S. arctica but twigs are hairless as in S. petrophila.

@margaret_eaglecap
I called this one Salix arctica var. petraea.

Bracts seem tawny on this one (at least not dark/black) as on S. petrophila and twigs are hairless as on S. petrophila.

Location not accurate. It was somewhere along the scree edge in Arethusa Cirque.
