BUD VARIATION" IN" THE VALENCIA ORANGE. 11 



ROUGH STRAIN. 



The trees of the Rough strain show more than ordinarily vigorous 

 vegetative growth, with a tendency toward the production of a 

 large number of suckers or abnormal branches, and bear smaller 

 crops than trees of the Valencia strain. The habit of growth is 

 usually upright and the foliage dense with large leaves. The 

 large proportion of trees of this strain found in some Valencia or- 

 chards is probably due to the use of sucker growth in propagating 

 the trees. 



The typical fruits, as shown in Plate VIII, are globular; size large; 

 texture coarse and rough; color yellowish orange; rind thick; rag 

 tough; juice medium in quantity and quality; seeds averaging 2 

 or 3 per fruit. On account of the inferior appearance of these 

 fruits they are of much less commercial value than those of the 

 Valencia strain. They are occasionally found as limb sports in 

 trees of the Valencia strain. 



SPORTING STRAIN. 



The trees of the Sporting strain are very variable in habit of growth 

 and production, are usually of more than ordinarily vigorous vege- 

 tative growth, and have rather dense foliage. The leaves are ex- 

 tremely variable in size and shape. 



The fruits, examples of which are shown in Plate IX, vary in a 

 manner similar to the tree characteristics and frequently include 

 examples of all of the observed strains of the variety and an unusual 

 number of other forms, such as those showing raised or sunken 

 sections, or both, sections of different strains of the Valencia oranges, 

 peculiar ridges or depressions, and abnormal shapes. Usually but 

 few fruits of the Valencia strain are borne by these trees, and on 

 the whole, their crop's are of very inferior value from a commercial 

 standpoint. 



FLAT STRAIN. 



The trees of the Flat strain are comparatively unproductive, with 

 an erect habit of growth and sparse foliage. The leaves are usually 

 small and sharply pointed. 



The typical fruits of this strain, as shown in Plate X, are distinctly 

 flattened at both the stem and blossom ends, giving them a very 

 characteristic appearance ; size medium; texture coarse; color yellow- 

 ish orange; rind thick; juice scant, of inferior quality; seeds averag- 

 ing about 3 per fruit. On account of their shape, these fruits are not 

 suitable for packing under prevailing conditions of marketing. This 

 strain is frequently found as limb sports in trees of the Valencia strain.
