CONCLUSIOiNS. 



SOME of the results of my researches may, perhaps, be 

 summed up as follows : 



(a.) The pubescence on the young shoots and under- 

 side of the leaves of the pummelo (C. decumana, 

 Willd.) cannot be considered a specific character, as 

 other huge Citrus have it also, and some pummelo 

 trees have it not. About this I may say that there is 

 no doubt in my mind. The pummelo appears to be a 

 huge form of some other Citrus, probably an orange, 

 and may have owed its hugeness to conditions of luxu- 

 riance in a tropical climate. 



(6.) The separation of the sweet oranges into two 

 distinct races, viz., the Portugal close-skinned orange 

 (C. aurantium sinense of Gallesio), and the Indian 

 loose-skinned suntara, or sungtara (Aurantium sin- 

 ense of Rumphius). Of this also I have no doubt. 



(c.} That the name suntara has nothing to do with 

 the name of the town of Cintra in Portugal, as has been 

 supposed by many, and that sungtara, one of its other 

 names, may partially have come from seng, which, 

 according to Rumphius, is the name of a variety of 

 orange in China. Not improbably also, its other 

 name, kamala, or kamla, may have come from kam, 

 the Chinese generic name for orange. 



(d.) The European words, lime and lemon, are 

 very probably derived from the generic names of the 

 Citrus in certain islands of the Malay archipelago.
