found to be equal to the most extravagant reports of its quality 

 and size, and the trees were very prolific in that section. The 

 trees sent to Florida produced equally good fruit, but they did 

 not bear well. This is why many fruit-growers thought there 

 was more than one variety in the lot of trees imported from 

 Brazil, but the difference in fruitfulness came from climatic 

 causes, as has been most thoroughly proved by many years of 

 experience in all the orange-growing sections of the country. 

 It has also been said that there was only one tree at the Tib-

 many parts of Florida and California, and compared them and

 pistils are also deformed in such a way as to render seed pro- 

 duction from the pollen of other varieties an impossibility, 

 except in a few very rare cases in which seeds have been found. 

 It is this malformation of the pistils or embryonic ovaries that
