 the petals. Ovary 8-ll(-14) celled. Fruit, juice-cells spindle-shaped. 

 Seeds oblong-ovoid, plano-convex, narrowed towards the attachment, with 

 a short oblique beak at the apex, wrinkled more or less. 



The Navel Orange with adventitious sections at the apex not 

 completely covered by the outer rind, and with very few seeds, sometimes 

 appears as a sport on trees in Jamaica (e.g. at Savoy), otherwise bearing- 

 ordinary oranges.

Seville Orange, Bigarade Orange, Bitter Orange. 



Cultivated and spontaneous ; native of China, Cochin-china, Malay Is., 

 and possibly India. 



Tree, much like C. Aurantium. Spines somewhat longer. Flowers 

 rather larger and more strongly scented. Calyx more regularly 4-5- 

 toothed. Petals 5(4), white, linear-oblong, conspicuously dotted with oil- 

 cells. Fruit, juice-cells sometimes smaller than those of C. Aurantium. 

 Seeds flattened, marked with ridged lines. 



The leaves are preferred to those of the Orange by perfumers for dis- 

 tillation for essential oil. The pulp and rind of the fruit makes the 

 best marmalade. The tree is resistant to foot-rot, and is therefore used 

 as a stock on which to bud the Orange, Lemon, &c. 



The Bitter-sweet or Seville- sweet Orange is a variety, the 

 flavour of the juice being sweet and pleasantly flavoured. 



6. C. nobilis Lour. FL Cocliin. 466 (1790) ; leaflet lanceolate 

 to elliptical, 5-10 cm. L, margin slightly crenulate ; scent of 

 leaves, fruit, &c. peculiar and characteristic ; petiole short, not 

 margined ; fruit somewhat globular, or pear-shaped, more or less 

 flattened or depressed at top and bottom, size variable, from 

 smaller than the sweet orange to about the same size, rind more 

 or less loose or baggy and easily removed, smooth or rough, 

 colour orange to reddish, pulp abundant, orange-coloured to 

 reddish, sweet and subacid with peculiar pleasant flavour, sections 

 and their coverings easily separable. Ait. Hort. Kew. ed. 2, iv.
