WILLOW-LEAF STRAIN 
The trees of the Willow-Leaf strain are somewhat spreading and 
drooping in their habits of growth. They are slow growing, with 
small, short twigs which make them dwarf and dense. The leaves 
are small and willowlike in shape, being very narrow and sharply 
pointed. 
The production of the trees of the Willow-Leaf strain is charac- 
teristically much less than that of comparable normal trees. The

fruits are of small size, light yellowish in color, and have coarse 
texture of skin and thick, somewhat ridged rinds. They are worth- 
less for marketing, but on account of their striking characteristics 
as compared with the normal Valencia fruits, they are of unusual 
interest in these investigations. 
In both foliage and fruit characteristics the trees of the Willow- 
Leaf strain are very conspicuous wherever found in Valencia 
orchards. Limb variations of the Willow-Leaf strain have been 
found in several otherwise normal Valencia trees, and entire trees
