30 BULLETIN 71, HAWAII EXPERIMENT STATION 



was introduced at the station from California in 1906, but the 

 trees from this source soon died and new material was obtained 

 from the late J. M. Whitney, of Honolulu. 



Fruit — Form, globate to oblate ; greatest diameter, 4 to 4% inches ; stem, stout ; rind, 

 3/16 inch thick; surface, smooth; oil cells, small and of yellow color; sections, 11 to 14; 

 pulp sacs, small, numerous and juicy ; flavor, a pleasing blend of acid sweetness and bitter 

 principle ; seeds, 60 to 80, with wrinkled coat usually extending into a broad wedge-shaped 

 wing. 



Foster 



The Foster is a comparatively new and early variety that has 

 become a favorite with many growers. The original tree was a 

 sport of the Walters which it closely resembles except that the 

 Foster has pink flesh. Graft wood was introduced at the station 

 from Florida about 1910, but the trees from it died and in 1926 

 a new supply was obtained from the late E. N. Reasoner, from 

 which a tree was set in the station orchard in 1928. 



Fruit — Form, oblate ; greatest diameter, 4% inches ; stem, small ; rind, smooth, pale 

 yellow, % inch thick ; sections, 12 or 13 : pulp sacs, of medium size, purplish pink, often 

 deepest in color next to the rind, shading to translucent near the core ; acidity and sweetness 

 good, bitter principle strongly marked ; seeds, 40 to SO, plump with seed coat flattening 

 into a wedge. 



Pernambuco 



The Pernambuco (fig. 4, B) was introduced into the United 

 States from Pernambuco, Brazil, through the United States De- 

 partment of Agriculture. Bud wood was obtained by the Hawaii 

 station in 1909 and the first trees were set in 1910-11. The fruit 

 matures from September to January. 



Fruit — Form, oblate or ovate ; greatest diameter, 4 to 4% inches ; stem, stout ; rind, 

 smooth, light greenish yellow ; oil cells, medium, sunken, % inch thick ; sections, 12 ; pulp 

 sacs, coarse, gray green ; acidity and sweetness, good ; bitter principle rather strongly 

 marked ; seeds, 60 to 80, plump and wedge-shaped. 



Tresca 



The original tree of the Tresca was a seedling grown by Fred 

 Tresca in Florida about 1887 from seeds obtained from the Ba- 

 hamas. Through vegetative methods of propagation the variety 

 was established and named by the late E. N. Reasoner. 



Fruit — Form, globate to pyriform ; greatest diameter, 4% inches ; color, dark lemon- 

 yellow ; apex, broad, flat, and usually scarred ; base, ridged and usually roughened ; rind, 

 y% to % inch thick ; oil cells vary in size, with large ones sunken ; sections, 14 or 15, 

 irregular in size ; pulp sacs, large and irregular, pinkish, juicy, with acid sweetness and 

 bitter principle well blended ; seeds, about 70, pinkish, small, and wedge-shaped. 



Woodworth 



The Woodworth was obtained by the Hawaii station from 

 Florida in 1906. This little known variety compares favorably 

 with other varieties grown in Hawaii. 



Fruit — Form, oblate ; greatest diameter, 4 x /4 inches ; rind, smooth, orange color, 3/16 

 inch thick ; oil cells, small, numerous, with a few sunken ; sections, 11 or 12 ; juice sacs, 

 small, break upon being separated ; acidity and sweetness are well blended and the bitter 

 principle is marked ; seeds, about 45, small, varying in size. 



Seedling No. 1557 



Seedling No. 1557 was grown from grapefruit introduced 

 from California in 1905. It is vigorous upright and prolific. The 

 fruit is attractive and compares favorably with that of estab- 

 lished varieties. 



Fruit — Form, globate or oblate; greatest diameter, 4 to 4 1 /f> inches; apex, sunken; rind, 

 Yi inch thick; surface, rough; oil cells, pitted; color, yellow; sections, 11 or 12; pulp sacs, 

 of medium size, adhering ; juice, acid and bitter principle well marked ; seeds, about 75, 

 small, plump, and with short wedge-shaped wing.
