Of the time in which different Grasses produce 

 Flowers and Seeds. 



To decide positively the exact period or season 

 when a grass always comes into flower, and per- 

 fects its seed, will he Ibund impracticable; (bra 

 variety of circumstances interlere. Each species 

 seems 10 possess a peculiar life, in which various 

 periods may be distinctly marked, according to the 

 varieties of its age, of the seasons, soils, exposures, 

 and mode of culture. 



The following table, which shows the time of 

 flowering, and the time of ripening the seed of 

 those grasses growing at Woburn which are men- 

 tioned in the Experiments, must therefore only be 

 considered as serving for a test of comparison, for 

 the different grasses growing under the same cir- 

 cumstances.
