THE BITTER, SOUR OR SEVILLE ORANGE ] 43 



production of orange-bitters, and in pharmacy as tincture 

 of orange-peel. 



2. The LARGE-CUPPED BITTER ORANGE. This variety 

 is notable for the swollen and fleshy calyx, which at 

 maturity assumes the same orange colour as the fruit. 

 The calyx of fruit which has dropped when young, usually 

 persists on the tree, and continues to grow, in due time 

 taking its peculiar orange colour. The fruit itself is not 

 distinguishable from the preceding and has the same 

 uses. 



3. The DOUBLE-FLOWERED BlTTER ORANGE. This 



is another ancient variety, remarkable for its blossoms 

 bearing ten petals or more, in a double row. The fruit 

 rarely reaches the size of the common bitter orange. 



4. The VARIEGATED BITTER ORANGE, in which the 

 leaves are partly coloured white or greenish white, and 

 the fruit has similar longitudinal markings, which become 

 deeper orange at maturity. 



5. The NARROW-LEAVED Or WILLOW- LEAVED BlTTER 



ORANGE, is distinguishable from the type on account of 

 its very narrow and long leaves, often not more than 

 i c. m. in breadth. 



6. The MALTA-CROSS BITTER ORANGE. The tree 

 is middling in size, with a dense crown of very dark 

 green foliage. The fruit is middling, bearing about eight 

 longitudinal ridges more marked at the navel end, so 

 disposed as to look like a Malta-cross. The colour of the 

 iruit is a very deep orange tending to scarlet. The tree 

 in fruit is very ornamental. 



7. The SMALL CHINA BITTER ORANGE. The tree 

 is middling or small, and makes slow growth. The leaves 

 are very small, and the fruit is small, hardly reaching 

 3 c. m. in diameter, and keeps on the tree for a lon^ 

 time. The fruit is candied whole. This variety when in 

 fruit is very ornamental, and fruits well as a pot plant.
