Vigna triodiophila (Fabaceae: Phaseoleae), a new conservation-listed species from the Pilbara, Western Australia
HOLLAND, A.E. AND BUTCHER, R.
The new species described herein came to light during botanical surveys of the Burrup Peninsula and surrounds in 2000; it is geographically restricted to basalt rockpile habitats in the north-west of the Pilbara bioregion. 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.
