lacking, as is shown in figure 4, C. The pollen of the flowers is scant 
in quantity and of low vitality. This condition accounts for the few 
seeds found in the fruits, as a rule. Occasionally, in a perfect flower 
the anthers develop an abundance of viable pollen, in which case the 
fruits set the normal number of seeds. 
The fruits, as shown in Plate III, are oblong, of large size, coarse 
in texture, and have very thick rinds. The rag is tough and abun- 
dant; the juice is scant, of poor flavor, and low acidity; and the fruits 
have an average of 2\ seeds. 
Fig. 7.— A typical lemon tree of the Pear-Shape Eureka strain, 10 years planted. The trees of this strain 
develop many small branches, giving them a dense appearance. They produce smooth, pear-shaped 
fruits with long necklike stem ends which are objectionable in packing the fruits for the market. 
PEAR-SHAPE STRAIN. 
The Pear-Shape strain was given a name descriptive of the shape 
of the typical fruits. While the trees and fruits differ in many charac- 
teristics from those of the other strains, the peculiar shape of the 
fruits is especially marked. These fruits must be clearly understood 
to be normal and healthy ones and not the diseased, undeveloped, 
or misshapen fruits often borne by trees suffering from unfavorable 
cultural conditions. 
The season of production of the fruits by the trees of the Pear-Shape 
strain is similar to that of trees of the Eureka strain and is more or 
less regular throughout the year. The yield is usually medium, but 
on account of the peculiar bottlelike shape of the lemons it is of 
inferior commercial value.
