Experiments in Crossing a Wild Pea from Palestine with Commercial Peas. 5 



mating the strong-stemmed and strong-foliaged cultivated Pea with the slender 

 and somewhat delicate Palestine Pea, which is, it should be remembered, an 

 introduction from a warmer climate, and may not grow so vigorously in England 

 as elsewhere.

Generally speaking, the hybrid plants grown this year (1911) are all stronger 

 and more vigorous in habit than the parental Palestine form, although some have 

 much of the same slender nature ; the serration of the leaflets is seen in some ; 

 those which have coloured blooms are bicoloured (instead of self-coloured as is the 

 Palestine Pea).
