Syn. Limo dulcis. Limetta Bergamotta. Peretta. Sweet Lime. 



This, unlike the former, has the habit of a tree. Its cul- 

 tivation is by no means general. 



5. C. Aurantium. Var. ». C. dulcis, [Siveet Orange.) Petiole 

 subalate. Leaves ovato-sublanceolate, slightly acuminate, with 

 a blunt point. Stamens 20-22. Fruit globose; rind thin; 

 pulp sweet. 



Syn. Narendj, (Avicenna.) Arangi, (Langue Romaine.) 

 Melarancio, (early Italian writers.) Aurantium, (Miller.) 

 Granger, (French.) Orange, (English.) 



This is a tree, often attaining 24 feet in height. Branches 

 for the most part erecto-patent. Leaves alternate, petiolated, 

 ovato-sublanceolate, slightly acuminate, with a blunt point, 

 and near the apex a few crenatures. Petiole winged, or sub- 

 alate. Spines axillary. Flowers axillary, peduncled, for 

 the most part solitary. Calyx 3-fid ; divisions obtuse. Co- 

 rolla of 4 petals, linear-lanceolate, obtuse, white. Stamens, 

 generally 22. Fruit yellow, smooth ; rind thin ; pulp white, 

 sweet. 



6. Var. /3. C. vulgaris, {Bitter Orange.) This differs little 

 from the preceding variety. The leaves are more acuminate, 

 and partake more of the lanceolate figure. The alee of the 

 petioles are broader. The calyx is, for the most part, regu- 

 larly 5-fid, with the divisions acute. Petals 4-5. Stamens 

 22. Peduncle minutely pubescent. Fruit, as in the former, 

 globose; rind more rough, and having a deeper shade of 

 red; pulp acrid. 



Although to the practised eye it is easy to distinguish be- 

 tween these two varieties, it is difficult to say in what the 

 distinctive marks consist. In general, the hitter Orange is 

 a tree of a more vigorous growth, the stem is taller, and the 

 leaves are larger and of a deeper green, with the crenatures 

 more distinct. The calyx is also more regularly 5-fid, and 

 the petals 5 in number, and suba?qual.
