Came across this liana in an open forest patch (moist deciduous) of Kumta, Karnataka.

Suspecting this to be a sp. of Derris.
May anyone help in ID ?

Derris eualata

I had come up to Derris thyrsiflora (Benth.) Benth. of Saldanha’s Fl. Ka. Still, there were doubts regarding the coloration of calyx and the no. of leaflets.
I agree for Derris eualata Bedd. which is a synonym of Derris thyrsiflora (Benth.) Benth.
And the accepted name is Aganope thyrsiflora (Benth.) Polhill
