tender, having a slightly bitter taste which is pleasant and agreeable. 

 The fruit has an ubundanee of juice that spurts when the fruit is cut. 

 The juice possesses the desired and typical grapefruit quality, a highly 

 developed pleasing flavor that is only equalled among California citrus 

 fruits, in the opinion of the writer, by the fine flavor of the Washington 

 Navel orange. Tiiis type is worthy of a separate varietal name in that 

 it has been successfully isolated in California by bud selection and is 

 being extensively propagated by California citrus growers. 



2. Seeded. The trees of this type differ but little in appearance or 

 fruiting behavior from those of the standard type. The fruit is very 

 similar in appearance to the standard type fruit and can hardly be 

 sorted out from that of the standard type by even the most experienced 

 workers. The fruit is usually heavily seeded, averaging about 75 seeds 

 eacli. Otherwise the characteristic quality of the fruit is as satisfactory 

 as that of the standard type. 



3. FlaUened and wrinJded. The trees of this type usually have a 

 more upright habit of growth than that of standard type trees. The 

 fruit has but few seeds, but frequently is lacking in juice, which is 

 likely to lack flavor, and is comparatively poor quality. The rag is 

 usually rather coarse and bitter. The wrinkled appearance around the 

 stem of the fruit detracts from its attractiveness for commercial pur- 

 poses. This type is distinctly inferior to the standard type. It 

 occasionally occurs as limb sports in standard trees, in which case it can 

 be eliminated by pruning. 



4. Corrugated. The trees of this type are similar in appearance to 

 those of the standard type. The fruit is usually globular in shape. 

 The rind is ribbed, so as to give a ridged or corrugated appearance to 

 the fruit and is usually thick. The color of the rind is likely to be 

 yellowish green and it never assumes the highly desired clean ivory- 

 white appearance. The rag is tough and very bitter, and the juice is 

 of inferior quality. This type also appears as limb sports in standard 

 type trees, in which ease it can be removed by pruning. 



5. Bell-shaped. The bell-shaped type trees are usually dwarfed in 

 appearance and have a drooping habit of growth. The fruit has a char- 

 acteristic bell, or pear-like, shape, resembling somewhat the shape of 

 typical shaddocks. The rind is usually very thick and the skin possesses 

 a yellowish cast. The rag is usually coarse and tough and the juice 

 of poor quality. The trees of this type are usually light bearers as 

 compared with trees of the standard type. 



6. Rough. The trees of this type are likely to have a dwarfed appear- 

 ance and produce but a light crop except at infrequent intervals. The 

 fruit, a representative sample of which is shown in Plates 3 and 4, is 

 usually globular in shape, unattractive in appearance, has a thick rind, 

 tough rag, an inferior quality of juice and many seeds. 



SPORTS. 



Aside from the types listed above we have occasionally found navel 

 grapefruit sports, fruit having raised or lowered sections, some resem- 

 bling closely in size, sliape, appearance and somewhat in flavor typical 

 Valencia or other oranges, and many minor variations of little import- 

 ance from a commercial standpoint. From the breeding viewpoint these 

 variations, or fluctuations from the standard and other types, are of 

 interest and possible importance.
