THE NATURAL SYSTEM. 121 



The Endogenous Petalifera are divided into two cohorts, vis. : 



5. The SpadiciflorcB, having the Howers on a spadix, as in 

 tlie Egyptian Calla and Jack-in-the-pulpit. 



6. The Floridim, having the flowers separate, not on a 

 spadix, as in Tulip, Gladiohis,. 



7. The Class Glumiferse constitutes the seventh cohort, 

 under {he name Oraminoids, i. e., the Grass-like plants. 



Six other cohorts are formed from the -flowtrless plants, 

 but we cannot notice them in this wort! 



259. Lastly, the cohorts are themselves divided into, or 

 cornposed of, the Natural Orders, which we defined in Les- 

 son XXX.
