Illustrated Descriptions of the Grasses 



beaches. The former spe- 

 cies is distinguished by 

 narrow panicles of erect 

 branches, the latter species 

 (which is also found in 

 sandy soil inland) by large, 

 widely opened flowering- 

 heads brilliantly painted 

 with vivid-coloured anthers 

 and stigmas. 



Nor is the above a com- 

 plete list of the Panic- 

 grasses that bloom in Eastern 

 States: in some localities 

 nearly a score of species 

 may be gathered within the 

 radius of a mile. Brilliant 

 tints are given to many, 

 purple and reddish brown 

 colour the green spikelets; 

 orange and terra-cotta tinge the anthers 

 of some, purple the anthers of others. 

 Often in the smaller species a few leaves 

 are dyed in crimson, and in the majority 

 of the Panic-grasses the feathery stigmas 

 are of deep purple.
