312 BIOLOGY: GENERAL AND MEDICAL 



Class IX. Basidiomycetes, the basidia 



fungi. 

 Phylum II. 



Bryophyta. The moss-like plants. 

 Class 1. Hepaticae, the liverworts. 

 Class 2. Musci, the mosses. 

 Phyhim III. 



Pteridophyta. The ferns and their allies. 

 Class 1. Filicineae, true ferns. 

 Class 2. Equistineae, the horse tails. 

 Class 3. Lycepodinese, the club mosses. 

 Phylum IV. 



Spermatophyta. The seed-bearing plants. 

 Sub-division 1. Gymnospermse. 

 Sub-division 2. Angiospermse. 

 Class I. Monocotyledons. 

 Class II. Dicotyledons. 



While most of the groups in this classification include 

 forms naturally related, the algae and fungi, respectively, 

 include sub-groups whose relationship is doubtful. 

 Thus, the bacteria are very likely more nearly related 

 to certain of the algae than to any fungi, though in habit 

 of life they are like the latter. 



THE ANIMAL KINGDOM. 



Division I. Protozoa. Unicellular animals. 



Phylum Protozoa. Sub-phyla. A. Gymno- 

 nomyxa (without perma- 

 nent form). 



B. Corticata (with perma- 

 nent form). 



Class I. Rhizopoda. Naked protoplas- 

 mic organisms with pseudo- 

 podia, without a localized oral 

 orifice. Multiply by binary 

 fission.
