Vigna."] l. le6tjmino-3^. (J. G. Baker.) 205 



VoANDEZiA stiBTEEBANEA, Thouars ; DG. Prodr. ii. 474, which is allied to Vigna, 

 but may be easily known by its 1—2 ovulate ovary, which, by the torsion of the pe- 

 duncle is thrust below the soil to ripen, and becomes a tuber-like pod, is occasionally 

 cultivated, but less frequently than in Tropical Africa. Its native country is not 

 clearly known.
