Vigna triodiophila A.E.Holland & R.Butcher is diminutive in all its parts and can be readily distinguished from other Vigna Savi taxa in the Pilbara by its small (to 2.3(.3) cm long to 1.6(.2.1) cm wide), ovate to elliptic leaflets which lack lateral lobing. The species has a conservation listing of Priority Three in Western Australia.
