RUTACEAE. — CITRUS 147 



are more pointed and less serrate than those of the citron, the twigs are more 

 slender, the flowers are smaller and in a number of other characters small but 

 clearly marked differences are found between the two plants. 



The oldest available name for the lemon seems to be Citrus Umonia Osbeck, 

 dating from 1765. The original Swedish edition of Osbeck's travels, published in 

 1757 did not give this plant a Latin name (Dagbok ofiver en Ostindisk Resa, 192). 

 This Osbeck added to the German translation published 8 years later. The ap- 

 plication of the name is rendered obscure by faulty translation of the description 

 in the German, and still more in the English edition of 1774, but the Latin diag- 

 nostic phrase published in the original Swedish edition applies very well to the 

 lemon. The Cantonese name given as " na-m§,ng " in Swedish is incorrectly given 

 as " Na-mang " in German, which has a very different sound. Dr. Hing Kwei 

 Fung, a Cantonese graduate of the Agricultural School of Cornell University, 

 recognized the name given in Swedish as being the colloquial pronunciation of 

 the words " ning mong " in Cantonese meaning a lemon, which is still commonly 

 grown and sold in pots as in Osbeck's day. Osbeck evidently intended to include 

 in this species the common lemons such as he saw growing in Spain, though he did 

 not find them in China. According to Bretschneider (in Chinese Recorder, III. 179 

 [1870]) the book name of the lemon is " Hsiang t'ao," fragrant peach, the name 

 " ning meng " (Giles, Chin. Diet. ed. 2, Nos. 8332 and 7767, the same as "ning 

 mong" in Cantonese) not being found in the books.
