CLASSIFICATION OP THE VEGETABLE KINGDOM. 



The Vegetable Kingdom is arranged in 5 Divisions. 



Division I. Thallophyta, Stemless Plants, or those which 

 are composed of a " thallus," i.e. organs of nourishment which 

 are not differentiated into root (in the sense in which this term is 

 used among the higher plants), stem, or leaf. Vascular bundles 

 are wanting. Conjugation and fertilisation in various ways; 

 among most of the Fungi only vegetative multiplication. 



In contradistinction to the Thallophytes all other plants are called " Stem- 

 plants '.' (" Cormophyta "), because their shoots are leaf-bearing stems. The 

 name Thallophyta (Stemless-plants) is to some extent unsuitable, since many 

 of the higher Algae are differentiated into stem and leaf. 



The Thallophytes are again separated into 3 sub-divisions, 

 namely : 



Sub-Division A. Myxomycetes, Slime-Fungi, with only 1 



class. 



Sub-Division B. Algae, with 10 classes: 

 Class 1. Syngeneticae. 



2. Dinoflagellata, Peridinea. 

 3. Diatomeae, Diatoms. 

 ,, 4. Schizophyta, Fission Algae. 

 5. Conjugatae. 

 6. Chlorophyceae, Green Algae. 

 7. Characeae, Stone-worts. 

 ,, 8. Phaeophyceae, Brown Algae. 

 9. Dictyotales. 

 10. Rhodophyceae, -Red Algse. 

 Sub-Division C. Fungi, with 3 classes: 

 Class 1. Phycomycetes. 

 ,, 2. Mesomycetes. 

 ,., 3. Mycomycetes, Higher Fungi. 



Division II. Bryophyta or Muscineae, Mosses. These 

 have leaf -bearing shoots, but neither true roots nor vascular
