extremely marked in this strain, so that the outer leaves become 
greenish cream colored. In the summer these trees are as dark green 
as those of the Valencia strain. 
The fruits borne by trees of the Dwarf strain are very small, of 
coarse texture of rind, and somewhat yellowish green in color. 
The parent tree of progeny trees Nos. 10-47 and 10-48, as listed in 
Table 4, was included in the original performance-record plot of the 
Valencia variety on the Chase plantation of the National Orange Co., 
near Corona, Calif. These progeny trees were propagated from a 
typical Dwarf limb variation and are true to type in all respects. 
One of these Dwarf trees is shown in Figure 5 with an adjoining 
tree of normal size and of the same age. Aside from the normal 
limbs, the parent tree also produced a limb variation which was 
named the Coarse Australian strain, as it had the rank vegetative

a similar limb variation, in comparison with a normal-sized tree (left) of the same age.

growth which is characteristic of the Australian strain of the Wash- 
ington Navel orange and bore rather large fruits with thick rinds 
and coarse texture of the skin. Progeny tree No. 10-45 (Table 4) 
was propagated from a bud taken from this Coarse Australian limb 
variation. 
It was not considered necessary to propagate from the normal 
part of the parent tree from which the Dwarf strain tree and Coarse 
Australian progeny trees were grown. Progeny tree No. 10-40, 
which was propagated from a Valencia strain tree in the same per- 
formance-record plot, has been used for comparison with the Dwarf 
and the Coarse Australian progeny trees. The performance records 
of the two progeny trees of the Dwarf strain, one of the Coarse 
Australian strain, and one of the Valencia strain are shown in 
Table 4. All the fruits borne by trees No. 10-47 and No. 10-48 have 
been small and coarse, typical of the Dwarf strain; those borne by
