A LEMON BUD VARIATION 



'rhe occurrence of navel fruits is ratlier common in citrus \'arieties. Fre- 

 quent examples of such fruits have been found in the individual tree 

 performance record studies of some of these varieties, other than the 

 Washington navel orange, in California and elsewhere in citrus 

 districts. For instance, several grapefruits with well developed navels 

 have been found in Alarsh trees. In the \'alencia orange studies 

 many fniits have been found with navels. l)ut none was absolutely 

 seedless. In jiicking the ])erformancc record lemon trees in California, 

 tiavel fruits have been found occasionally. The accomjianying photo- 

 graph shows (natural size) a navel lemon with a large ])rotru(ling navel 

 This fruit contained several seeds. It was produced l)y a normal tree 

 bearing, except for this specimen, nonnal fruits. The trees of the 

 Ruby Blood variety of orange, and the Dancy variety of tangerines, 

 in California, ])roduce very many fruits having navels. None of these 

 fruits, however, that has so far been found by the writer, is seedless, or 

 promises to l)e of any particular value commercially. They are 

 interesting mainly from the standj^oint of enii)hasizing the frequency 

 of the occurrence of striking buil variations in citrus varieties.
