witha thick or thin rind ; pulp pale, sharply acid. According to Watt 

 this is the kind which is usually met with in a wild condition in the warm 

 valleys of the Himalaya and in other localities mentioned above under 

 Q, medica, L. Several forms, varying in size and in the thickness of the 

 rind, are in cultivation in various parts of India. The small oval juicy 

 thin-skinned kind, called Kdghzi Ume, is much valued.

 white. Fru%t\glohose or ovoid, shortly mammillate _; rind with concave 

 vesicles. Cultivated in most parts of India, and indigenous to S. India 

 according to Wight. Kurz in For. Fl. Burma, i, 197, reduces this to 

 C. nohilis, Lour. The fruit is largely used medicinally. Watt agrees 

 with Kurz in separating this plant from the sweet lemons (C. Lumia), and 

 he also is of opinion that the majority of the forms descrihed by Roxburgh 

 under his C. acida should be included under C. Limetta. and placed quite 

 apart from C. medica. On the other hand Bonavia in Journ. Linn, Soc. 

 xxii, 2.13, maintains that all the cultivated true limes of India and Ceylon 

 have been derived from G. Hystrix DC, (F. B. I, i, 515). The winged 

 petiole is a very constant character of the limes, and in C. Hystrix, which 

 he considers to be the original ancestor, the petioles are very largely 

 developed.

 Bonavia recognizes four races of sweet oranges, viz., (1) Santara, (2) 

 Keonla, (3) Portugal and Malta, (4 ) Mandarin. The Santara kind is best 

 distinguished by its loose skin. It is largely grown in the neighbourhood 

 of Delhi, and also in the Nagpur district of the Central Provinces. The 

 orang.es grown in Sylhet, Bhutan, Nepal and Garhwal belong also to this 

 class. These latter and the Nagpur oranges have a much thinner rind 

 than that of the Delhi kind. An orange belonging to this class has been 

 reported as apparently wild in the hot valleys at the foot of the Himalaya. 

 The Reonla, or ordinary naringi of Upper India, has a rough dark- 

 coloured clinging rind. It can stand a greater amount of heat than the 

 Santara, and is more generally diffused over India ; the pulp is not nearly 

 ao sweet. Bonavia alludes to a form of Keonla called Kokni, which is
