 arises a single style whicli is 3-lobed 

 at its summit. There seems 

 to be reason, therefore, for 

 calling this flask-like body a 

 perianth ; but the staminate 

 flower is naked.

 (or racheola) which arises be-

 racheola not infrequently 

 projects beyond the flower 

 and bears other flowers 

 (&) ; and in some kinds 

 of carex a similar struc- 

 ture is the rule. If this 

 branch is inside the flask- 

 like body, then that bod"" 

 cannot be a perianth, but 

 must be a reinforcement of 

 the flower.
