[ Greek, amphi, on both sides, and citrpos, fruit ; producing fruit both above and under ground.] 



Flowers of two kinds ; those of the upper many-flowered racemes perfect and petaliferous, 

 but often sterile ; those at the base of the stem or underground mostly on one- or few- 

 flowered peduncles, imperfect and deformed, but usually fertile. Perfect fl. Calyx 

 tubular-campanulate, 4-toothed, without bracts. Vcxillum incumbent, and partly folded 

 round the other petals. Ovary 4-ovuled : style smooth : stigma small, capitate. Legume 

 linear-oblong, stipitate, compressed, somewhat scimitar-shaped, 3 - 4-seeded. Imperfect 

 or Apetalous fl. Calyx nearly as in the petaliferous flowers. Corolla none, or with the 

 rudiment of a vexillum. Stamens either wanting or 5 - 10, several of them bearing perfect 

 anthers, the others rudimentary : filaments distinct. Ovary 1 - 3-ovuled, with a short 

 recurved style. Legume obovate or pyriform, 1 - 2-seeded, usually maturing beneath the 

 surface of the ground. — Annual, twining or sarmentose herbs. Stems retrorsely pubescent. 

 Leaves pinnately trifoliolate. Stipules resembling the bracts, striate. Racemes of the 

 perfect flowers often somewhat compound : bracts orbicular, often emarginate or 2-cleft 

 (each formed by the union of a pair), clasping.
