BUD VARIATION IN THE EUREKA LEMON. 21 
The trees, as illustrated in figure 7, are very finely branched; so 
much so that they can quickly be identified by the masses of small 
branches and their rather brushlike appearance. The leaves are 
usually small in size, ovate in shape, with sharply pointed tips, 
abundant in number, and of a rather light green color. The flowers 
are perfect and similar to those of the Eureka strain except that the 
pollen is usually small in quantity and of low vitality. 
The typical fruits of the Pear-Shape strain, as shown in Plate IV, 
are conspicuously and markedly different from the fruits of the other 
strains. The lemons are oval or pear shaped,, with frequently elon- 
gated or bottle-necked stem ends, and of small to medium size. The 
rind is thin and of a very smooth, fine texture. The rag is tender, 
and the juice is abundant and of low acidity. The fruits average 
about two or three seeds. 
DENSE-PRODUCTIVE STRAIN. 
The trees of the Dense-Productive strain differ from those of the 
Eureka strain mainly in their habit of growth and density of foliage. 
These trees have a dense appearance, owing to the larger number of 
branches and leaves, and the fruits are largely covered by the pro- 
tecting foliage. The leaves are of medium size, oval shape, obtuse, 
abundant in quantity, and from deep to dark green in color. The 
flowers closely resemble those of the Eureka strain. 
The fruits are oblong, medium in size, of smooth texture, and with 
little or no tendency to ridging. The rind is medium thick, the rag 
is tender, the juice is abundant and of high acidity, and the fruits 
average between six and seven seeds. 
Owing to the habit of growth of the trees and the density of foliage, 
the fruits are less likely to climatic injury, or sunburn, than those of 
the Eureka strain. This condition makes up in part for the somewhat 
lower production of the trees of this strain as compared with those of 
the Eureka strain in the performance-record plats. 
VARIEGATED STRAEN. 
In the tree-census studies of Eureka lemons in the orchard in which 
the performance-record studies were carried on, branches bearing 
one or more variegated fruits and entire trees producing crops of 
variegated lemons were discovered. On account of the striking color 
contrasts of both the fruits and the foliage, representative fruits, 
branches, or trees of the Variegated strain were easily located. 
The habit of growth of the trees of the Variegated strain is open, 
the production of fruits is good, and the trees bear fruits during all 
seasons of the year. The bark of the -young branches is variegated 
with fine stripes of shades of green and straw color (Nos. 31 L, 29/", 
25 , "b, and 21.'d of Ridgway's Color Standards, edition of 1912). 
The leaves are oval in shape, obtuse, of medium size, fairly abundant
