 ^hich is, however, described as a bush with white flowers. — The Sour Lime of India.

 nate, petiole often broadly winged, flowers pure white bisexual, fruit globose 

 generally oblate not mamillate. 



Hot valleys along the foot of the Himalaya, from Garwhal eastwards to Sikkim; and 

 in the Khasia Mts. 



A small slender tree, flowering in the rains, and fruiting after them, growing ,where 

 I have found it in the very bottoms of valleys, and where it did not occur to me to doubt 

 its being indigenous. The fruit was somewhat flattened or nearly globose, about 2 in. 

 diam. , high coloured, and uneatable, being (if I remember aright) mawkish and bitter.' 

 The following are the principal cultivated varieties : — 



Vab. 1. Aurantium proper ; petiole naked or winged, pulp sweet yellow rarely red. 

 Brandis, For. Fl. bZ. C. Aurantium, L.; Eoxh. Fl. Ind. in. 2,92 ; W. & A. Prodr.,
