THE ACID LIME FRUIT IX HAWAII.

ica (PL IV). It is grown mainly in the West Indies, Florida, and 

 Mexico. This variety is a shrubby bush that attains a height of 

 from 6 to 10 feet. It is well provided with small, sharp thorns, and 

 with rather small, light-green foliage. 



Fruit : Ripens practically the year around. Form, oblong to oval ; 

 size about 2 or 2i inches long (large size range from If to 2 inches 

 in diameter) ; surface light lemon-yellow; apex usually smooth with 

 a blunt point when nippled; base usually smooth and occasionally 

 elongated to neck form ; rind smooth and very thin ; oil cells numer- 

 ous; segments 10 or less in number and distinctly marked; divid- 

 ing tissue thin; flesh fine-grained and of light green color; pulp 

 vesicles small and spindle-shaped ; juice plentiful and of translucent 

 color; pulp soft to melting; acid very strong, the flavor being dis- 

 tinctly of the lime ; central pith open and small ; seeds few to many, 

 and in shape flat, like a wedge, to rather pointed. 



Several closely related forms grow in Florida. 3 Palmetto, which 

 is the result of a cross between West Indian and the common lemon, 

 and Everglade, the progeny of West Indian with pollen of the 

 pomelo, are said to be excellent fruits. Thornless, another lime of 

 the Mexican type from British Dominica, developed as a sport about 

 1891. Absence of thorns is a desirable feature in lime culture. 



RANGPUR. 



The Rangpur, also known as Rungpur or Rungpor, 4 originated in 

 India (PL V). Although an acid fruit it is not considered a true 

 lime. It is hardier than the true lime and is said to belong to the 

 Suntara orange group of India. The color of the fruit, the ease 

 with which the peel separates from the pulp and the segments from 

 each other, as well as its peculiar flavor, are characters indicating 

 relationship to the well-known mandarin group of citrus fruits. 

 Owing to the character of the fruit and certain habits of the tree, 

 the Rangpur is grouped with the lime only provisionally. Its 

 introduction into Florida by means of seeds has doubtless been 

 the means of its reaching Hawaii. Several trees of this variety, 

 introduced into Hawaii from Australia by Judge S. B. Dole, have 

 made good growth and are prolific. 



The Rangpur lime tree is small and of spreading habit. Its 

 branches are thorny, the foliage is rather sparse, and the small, 

 light-green leaves have rounded apexes but no stipules. 



Fruit : In season in fall and winter. Form, round, oblate, tending 

 toward obovate, occasionally necked; apical nipple sharp-pointed; 

 apex usually flat; base depressed at stem, or ridged when necked; 

 size medium with diameter of 2 or 2^ inches; rind inclined to be 

 rough, medium in thickness, easily separated from the pulp, and 

 of irregular color that becomes orange red on ripening; segments 

 regular, 7 or 8 in number, and easy to separate ; pulp vesicles large, 

 plump, and pointed; flesh orange-colored; juice plentiful and of an 

 agreeable flavor that is peculiar to the variety; central pith small 

 and open; seeds plump, 7 to 18 in number, with little or no point, 

 and of a greenish hue on the inside.
