by the progeny trees shown in Figure 3. Riverside, Calif., January, 1926. (About 
two-thirds natural size) 
DWARF STRAIN 
The trees of the Dwarf strain of the Valencia orange are very slow 
growing and smaller even than those of the Willow-Leaf strain. The 
twigs are very small. The foliage is dense, the leaves being small,

The trees bloom profusely, but produce only very light crops.
