as the ripe one. Probably the following is the mistake 

 Humayoon made : The kalan kaghzi nimboo, shown 

 on pi. 189, figs, a, c, and e, when ripe, is indistin- 

 guishable in all respects from the sherbetee nimboo 

 shown on pi. 191, fig. a, except that the former is sour, 

 while the latter is sweet. Both are globose thin- 

 skinned lemons, and Humayoon may have tasted an 

 unripe kalan kaghzi lemon, mistaking it for an unripe 

 amratphal. 



The Pundits of Benares quote a much older work 

 than Baber's memoirs, in which the Citrus is men- 

 tioned. This work is called madanpal m'ghnntZi

 1354 A.D. and is therefore upwards of 500 years old.

 Which kinds are meant it is impossible to say, but 

 by the latter name possibly some large variety, like 

 ihegulgut) may be meant.

 varieties of C. medica is that it has spherical fruit 

 and sweet, non-aromatic juice. There are, however, 

 several sweet citrons proper, and they have been also 

 referred to by Baber under the name of Lemghanat 

 citrons. De Candolle also says that in India this 

 Citrus is called the sweet lime. Wrongly so-called, I 

 think, because it appears to me no other than a sweet 

 lemon. He also says that " the botanist Wight affirms 

 that this last variety is wild in the Nilgiri hills." (?) 



Sir J. Hooker makes the sour lemon, var. 2, C. 

 medica limonum ; and of the sweet lemon, var. 4, C. 

 medica limetta, and includes in the latter the sweet 

 lime and sweet lemon of Risso. Of the sour lemon, 

 he says " leaflet ovate, petiole margined or winged,
