in number, and variegated in color, as shown in Plate V. The white 
and green sections of the leaves occur in areas of variable size and 
shape, in some cases the leaves being almost wholly green, while in 
others they are nearly or entirely white. The flowers are perfect and 
apparently like those of the Eureka strain. 
The fruits are oblong in shape, of medium size, and rough or ridged 
in texture. The rinds are thin. The rag is tender, and the juice is 
abundant and somewhat lacking in acidity. The seeds are similar in 
number to those of fruits of the Eureka strain. 
The fruits have a striped appearance, usually with alternate green 
and white areas. Accompanying this appearance there is usually a 
ridged condition which accentuates the striped appearance. The 
ridges are usually green and the intermediate spaces white. Not 
only are the leaves and fruits striped or variegated, but the bark of 
the branches on the trees of this strain also has a similar appearance. 
The rough texture of the fruits, their variegated appearance, and the 
thin rinds, which are liable to split, makes them of inferior co mm ercial 
value. Many citrus growers in California have taken bud wood from 
the variegated trees in the performance-record plats in order to grow 
one or more trees for ornamental purposes. 
The chief value of this striking variation lies in its occurrence as 
single-fruit, branch, and entire-tree variations of the Eureka variety, 
thus demonstrating its origin from bud variations. 
SPORTING STRAIN. 
In one instance in the performance-record plats, and occasionally 
throughout the 250-acre grove of Eureka lemons in which these plats 
are located, trees have been found in vigorous vegetative condition 
with many branch variations, as shown by both the vegetative and 
fruit characteristics. In a Sporting tree in one of the performance- 
record plats, different branches, all grown from a single bud, produce 
typical fruits of all of the strains under observation and several minor 
variations of the Eureka variety. Plate VI shows specimens repre- 
senting several strains and variations borne on one tree grown from 
a single bud. A similar condition of variability has been observed 
frequently, so it seems apparent that there exists a strain of the 
Eureka lemon which breaks up into many variations having very 
diverse characteristics. Other trees are often found in which only 
one or two branches are producing fruit of some strain or variation 
different from the rest of the tree, as illustrated in Plate VII. 
The trees of the Sporting strain vary in productiveness and season 
of production corresponding to the proportions of the various strains 
produced by them. If the productive strains are dominant, the trees 
are productive, while if the unproductive strains are most evident 
the trees are unproductive. As a rule, the trees are comparatively 
large and show a very vigorous vegetative condition, as illustrated
