 the normal number is only three. Fig. 80 shows this augmenta- 

 tion of the flower cluster. Like the doubling, this enlargement of 

 the cluster is not perpetuated by seeds, but it is not too much to 

 expect that a permanent modification in this direction may come in

 iar accumulative effects of domestication which is apt to appear 

 somewhat simultaneously in widely separated regions, evidently 

 largely l)ecanse an equal degree of domestication tends to produce 

 similar effects in any number of regions. The same thing is 

 illustrated in the dwarf Lima beans (see our Bulletin 87), and it 

 transpired long ago in the couimon garden beans. The California 

 dwarf, which is introduced this spring (IS'.Kj) by Burpee as Cupid,
