Typical Fruits of a Corrugated Variation Found on a Tree of the 

 Open Strain of the Lisbon Lemon. 



This variation has been frequently found as individual fruit, limb, and entire tree bud sports. 

 The fruits are commercially worthless, but are interesting as throwing light on the origin of 

 lemon strains from bud variations. Nearly natural size. The fruit at the lower right hand 

 is 2 J inches long.
