Vigna.~\ L. LEGUMINOSJ:. (J. G. Baker.) 205 



VOANDEZIA STJBTERRANEA, Thouars ; DC. Prodr. ii. 474, which is allied to 

 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.
