Flower of Jawa 2: 1 image.
Could you help me identify our Phanera please.

I think flowers are needed.

The shape of the leaves and the veins remind me of Bauhinia sp.

Yes, Phanera is related to Bauhinia.

Seems to liana, Phanera vahlii,

I cannot identify but definitely not Phanera vahlii because its young leaves never have this colour.
