54 CITRUS LIMONUM 



Canaries, the Azores, and in all tropical and subtropical countries, 

 but it appears that there is no certain notice of it in Europe 

 before the latter part of the 15th century. The wild stock is 

 native in the north-west provinces of India, ascending to 4000 

 feet in the mountains, where several forms are met with in a 

 natural state. Under cultivation numerous races have been pro- 

 duced, of which Kisso and Poiteau enumerate no less than 47, 

 though they maintain as distinct the Sweet Limes (C. Limetta, 

 Bisso, with 8 varieties, and G. Lumia, Kisso and Poit., with 

 12 varieties). These "sweet" Lemons differ, however, only in 

 their fruit possessing an insipid instead of an acid juice. The 

 Lemon is a more tender plant than the orange, but is frequently 

 grown in our conservatories ; it flowers and fruits nearly all the 

 year round, and the scent of the flowers is very sweet, but quite 

 distinct from that of orange blossoms.

 into this country from southern Europe, principally from Sicily, 

 but to some extent from Spain and other parts. The lemons are
