THE ORANGE TRIBE. 339 



a native of Asia, but is cultivated in the south of Europe. 

 There are numerous varieties. 



C. Aurantium, Sweet Orange. — The petioles almost 

 naked ; fruit globose, with a thin rind and sweet pulp. 

 Risso has enumerated nineteen varieties; of which the 

 principal are, the China, the Portugal, and the Maltese. 

 The last has a blood-colored pulp, with rich juice, and is 

 now much in request. The Tangerine orange may be cul- 

 tivated successfully in a common flower-pot, producing 

 fruit of delicious quality for the dessert. 



C. Bigarda, Seville or Bitter Orange, the most hardy 

 of the tribe. The petioles winged ; fruit globose, with a 

 thin rind, and bitter juice. This sort is employed for 

 making marmalade, and is also used in medicine. Twelve 

 varieties have been described. 



C. Decumana, the Shaddock. — The petioles broad, with 

 cordate wings ; fruit large, round, weighing from ten to 

 fourteen pounds, with a thick rind. This fruit was car- 

 ried by Captain Shaddock from China to the British West 

 Indies, where it first acquired the name which it here bears. 

 It is now cultivated not only in the West India Islands, 

 but extensively in South America. Four sorts are enume- 

 rated. Of all the Citrus tribe, this has the most beautiful 

 foliage, and it is therefore not improperly selected for fill- 

 ing the back wall of a vinery. 



The Orangery, in England, seldom differs in form, even 

 where it is a separate structure, from that of the green- 

 house. Most commonly, the few orange plants which are 

 kept are grown in large pots, or in tubs or boxes, and oc- 

 cupy a place with other exotics on the green-house shelves. 

 When the trees are of considerable size, the boxes or square 

 tubs are so constructed that they can be partially taken to 

 pieces without materially disturbing the roots of the plants;
