Peas and Beans 



relatively small and slender grower, early and compara- 

 tively hardy, apparently annual, with thin, short and 

 mostly broad (ovate-pointed) leaflets, numerous small 



papery pods much 

 curved on the back 

 and provided with 

 a long upward 

 point or tip and 

 with the habit of 

 splitting open and 

 twisting when ripe, 

 discharging the

seeds beans small and flat, white, 

 marked with red (Fig. 141). 



2. The true lima bean (P. lunwtiis var. macro car pus) , 

 distinguished from the sieva by its tall growth, lateness, 

 greater susceptibility to cold, perennial in tropical climates, 

 large thick often ovate-lanceolate leaflets, and fewer thick 

 fleshy straightish (or sometimes laterally curved) pods 

 with a less prominent point and not readily, splitting open 

 at maturity; seeds much larger, white, red, black or 

 'speckled (Figs. 143, 143). Of this true or large lima 

 two types are in cultivation : 



(a) The Flat or Large-Seeded limas, that have large 

 very flat and more or less lunate and veiny seeds, very 

 broad pods with a distinct point, and broad ovate leaf- 

 lets (Fig. 144). 



(b) The Potato limas, with smaller and tumid seeds, 

 shorter and thicker pods with a less prominent point, 

 and long-ovate leaflets tapering from a more or less an- 

 gular base into a long apex. There are dwarf forms.
