limes, lemons and citrons found in cultivation within the area of the 

 Upper Gangetic Plain. 

 'For a clear and concise account of the botanical classification of " this 

 genus the ' reader is referred to page 51 of Sir Dietrich Brandis' "Forest 

 Flora of N. W. & C. India" Although 27 years have elapsad since the 

 publication of, that very useful work, very little additional information 

 has been contributed towards ascertaining the true origin of some of the 

 species and varieties of this difficult genus*. It is often not an easy 

 matter to decide whether certain kinds of oranges and lemons, which 

 ■ are now growing apparently wild in many parts of India, are really 

 indigenous, or merely represent remnants of some ancient cultivation, 

 all other signs of which having become obliterated.

* The following important works relatinsr to the genus Citrus have been published 

 since the appearance of Brandis' Forest Flora :— Hook, i, in Fl. Brit. Ind. Vol. I, p. 

 514 i\i which Brandis' arrangement is closely followed ; Bentley and Trimen, Medi- 

 einal Plants (1880) ; DeCandoUe, " L'Orig. PI. Cult. " (1883) ; Dr. Watts' " Dictionary 

 of the Economic Products of India, " Vol. II (1889 ) ; Bonavia, " Oranges and Lemons 

 «f India and Ceylon," with Atlas of Illustrations (1890), This latter work should be 

 situdied specially with reference to the origin of the numerous cultivated varities of these 

 plants.
