THE NATURAL SYSTEM. 121 



The Endogenous Petalifera3 are divided into two cohorts, vis. : 



5. Tiie SjMdlcifiorcB, having the flowers on a sj)adixj as in 

 the Egyptian CalLa and Jack-in-the-pulpit. 



6. The Floridice^ having the flowers separate, not on a 

 spadix, as in Tulip, Gladiolus. 



7. The Class Glumiferee constitutes the seventh cohort, 

 under the name Graminoids^ i. e., the Grass-like plants. 



Six other cohorts are formed from the flowerless plants, 

 but we cannot notice them in this work. 



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

 composed of, the Natural Orders, w^hich we defined in Les- 

 son XXX.
