I guess it is correct ID according to the elevation.

Help ID Dactylicapnos from Phulchowki : 3 posts by 1 author. Attachments (2)
I had some help to get this plant to the genus Dactylicapnos, but would like to see if anyone can confirm the species level ID Dactylicampnos odontocarpa. Location is along the Phulchowki road, south of Kathmandu elevation 2658m. It was blooming from mid-September to late October.

Leaves are not clear.
May be Dactylicapnos macrocapnos (Prain) Hutch. as per comparative images at Dactylicapnos

The foliage appears to be soft with indistinct veins and alternate primary leaflets, which tells us that this is either the D. macrocapnos complex (incl. D. odontocarpa) or D. scandens. These species are most easy to separate by nectary and ripe fruits, but even without these, the direction of pedicels and the dizzy fruit in the background make me sure that your plant is D. scandens. It has also been collected in this area before.
I enclose a picture of a verified D. scandens for comparison.
