NATURAL CLASSES. 73 



They differ from true stemy or caulescent plants 

 by the roots being crowned by radical leaves 

 and sending forth a leafless stem called scape, 

 which is merely a peduncle bearing the flow- 

 ers. They blend often with them, and with 

 annuals. 



IG. Cladomes, with branched or umbellate 

 Scape, Frimula, Statice. 



17. Scapomes, with a simple scape, Planta- 

 go^ Dionea. 



VI. Class, BoTANES or Herbs, Annuals. 

 Root dissimilar, but slender, fibrose, annual or 

 biennial; sending forth only once a stem, bear- 

 ing flowers, with or without leaves — In i'act 

 Plants and Herbs are hardly distinguished by 

 usage, yet easily known by their small roots : 

 they blend by biennial roots, and have some- 

 times scapose stems. Hence the Orders must 

 be different, since here ends the woody or hard 

 stems or roots. 



18. Dlnomes, commonly biennial root, rad- 

 ical leaves, and stem leaves diilerent, Verbas- 

 cum. 



19. Stemilomes, Stem leafy, Vapaver. 



20. Rhizilomes, Root leafy or crowned, scape 

 leafless, Erophila. 



21. Aphilomes, No leaves, Ciiscuta, &.c. 



2d Series, ENDOGENES. 



VII. Stelmians or crowned Trees. Stem cy- 

 lindrical seldom branched, with spungy wood, 

 crowned with leaves on the top ; roots dissimilar. 



22. Palms, Leaves flabellate or pinnate, 

 flowers central.
