GRAND DIVISIONS OF THE VEGETABLE KINGDOM. 



Sab-Kingdom CORMOPHYTA. Plants in which (with 

 few exceptions) there is a well-marked differentiation into cau- 



lome and phyllome. Life-history of the individual exhibiting 

 more or less distinctly an alternation of generations — a sexual 

 generation and a non-sexual generation — each of which de- 

 velops from a single cell formed by the other. 



Branch PHANEROGAMIA. Producing seeds. Fibro- 

 vascular bundles present. (See Gray's Manual.) 



Branch PTERIDOPIIYTA. Not producing seeds. Fibro- 

 vascular bundles present. (See Gray's Manual.) 



Branch BRYOPHYTA. Not producing seeds. Fibro-vas- 

 cular bundles absent. (See page 10.) 



Sub-Kingdom THALLOPHYTA. Plants in which there 

 is no well-marked differentiation of caulome and phyllome. Life- 

 history of the individual never exhibiting a true alternation of 

 generation-. 



Group ALG2E. Provided with chlorophyll, which in some 



cases is marked by other coloring matters. Mostly aquatic, 



or growing in moist situations. Never truly parasitic or 



saprophytic. Of rather slow growth. (See page 18.) 



Group FUNGI. Destitute of chlorophyll. Either parasitic 



or saprophytic. Of rapid growth. (See page 21.) 

 Group LIC 1 1 EN ES. Vegetable growths consisting of a fun- 

 gns parasitic on algre imprisoned among its tissues, the two 

 kinds of plants leading a symbiotic existence. The com- 

 posite thallus epiphytic, of slow growth. (See page 2 ( J.)
