172 SYSTEMATIC POMOLOGY 



Waugh's Artificial Classification 



The writer of these lines not long ago pre- 

 pared a tentative classification of pears on 

 arbitrary lines which may properly be repro- 

 duced here.* The classification rests upon 

 three separate characters, as follows: 



I. Form The pears may be divided into four 

 classes, according to form of the fruit, as fol- 

 lows: 



1. Round or oblate pears; those not tapering 



toward the stem. 



2. Obconic pears; those tapering more or less 



toward the stem, but not constricted into a 

 neck. 



3. Pyriform pears; those having a visibly con- 



stricted neck. 



4. Irregular pears: those markedly irregular, and 



not conforming to any of the foregoing 

 classes. 



II. Season Each of these four classes may be divided 

 into three orders according to the season of 

 ripening of the fruit *>., summer pears, 

 autumn pears, and winter pears. 



III. Color Each of these twelve orders may be 

 divided into three groups, according to the 

 color of the fruit, as follows: 



i. Uncolored fruit i.e., fruit which is pure 

 green, or, when ripe, pure yellow.
