PROLIFICATION OF THE INFLORESCENCE. 



113 



Professor Reichenbach enumerates a few instances in 

 the Report of tlie International Botanical Congress of 

 London, 1866, p. 121, and the same author gives an 

 illustration in his * Orchidographia Europoea,' tab. 150. 



In Grasses, as indeed in other plants with a spicate 

 inflorescence, this change occurs not unfrequently. 

 The common Ray Grass {Lolium) is especially subject 

 to the change in question, and among cultivated 

 cereals, maize and wheat occasionally show this ten- 

 dency to subdivision. One variety of the latter grain 

 is cultivated in hot countries under the name of 

 Egyptian wheat Triticwm vuJgare, var. compositum. 



Prolification of the inflorescence has been most fre- 

 quently observed in the following genera : 



Leafy. 



Floral.
