The F' iiybrid plants were gencrally lallcr llian llic Palcsline Pea and 

 serralion in thelcaflels in a modified l'orm wasnoticeable. Colon reil IIom ers were 

 dominant over while, although llie blooms wei'e bicoloured and not stdf coloured. 



In 1"^-, plants willi while blooms, aiso plants wilh enlire leallels were 

 produccil, bnl no })lant was found which could be described as a \\ hileilowered 

 type of Ihe Palestine Pea, lliough il is of course passible thaï siicli a lype niay 

 hâve appeared and died ofl' prematurely. 



II cannol be claimed as a resuit of my experiments thaï Ihe Palestine Pea 

 is cerlainly Ihe forerunner of présent day garden Peas, for w liilsl on Ihe one 

 hand llie fact Uial some of llie hybrids are fertile niiglil not preclude such a 

 possibilily, yet on Ihe other hand the colour of llie tlowers, llie serraled leallels, 

 Ihe woolly nature of the inlerior of llie pod, the type of seed. and the slerilily 

 of iiiosL of liie hybrids would perhaps point lo itsnotbeing so.
