i3. CI'CER arietfrmm, the Chick Pea, rarely cultivated may be

 Calyx segments leafy, the upper two shortest ; vexillum large, reflexed ; 

 stamens 10, diadelphous (9 and 1) ; style grooved on the back, villous 

 and stigmatic on the inner side ; legume oblong, tumid, many-seeded ;

 2 to 3' long, $ as wide, obtuse, mucronate, stip. rather larger than the leaflets. 

 Fls. two or more, on axillary peduncles, large, white. This plant has been cul- 

 tivated from time immemorial, so that its native country is unknown. There 

 are many varieties.
