SPORT, a plant, or portion of a 

 plant, which has suddenly 

 assumed an appearance very 

 different from that character- 

 istic of the variety or species; 

 a seed- or bud-variation, but

 peculiarity is not usually capa- 

 ble of being perpetuated by 

 seed. When a sport is propa- 

 gated artificially it continues 

 to be called a sport. Mon- 

 strosities or extreme malforma- 

 tions are not usually given this 

 name. See Variation, Seed- 

 variation, and Bud-varia-
