S6 BRACTS 



leaves are termed the prophylls. The same holds good for the 

 branches of inflorescences. Thus the stalk of each lateral 

 flower of a Monocotyledon often has a prophyll on that face 

 (posterior face), which is towards the axis bearing it. In 

 Dicotyledons, the stalk of a lateral flower often has two 

 prophylls on its sides, as is shown in fig. 98 fir, and is 

 clearly seen in the Violet (fig. 158, j). These prophylls are 

 therefore bracts occupying definite positions in the inflorescence. 

 Occasionally no prophylls occur on the flower-stalk : examples, 

 Wallflower, Arum maculatum.
