729. By some recent authors, this system has been modified, so as 

 to include, under CorolliflorEe, all Dicotyledons with united petals, whe- 

 ther hypogynous or not, and to exclude from Class II. all plants 

 Avithout flowers. It is then presented in the following form :

730. SYSTEM OF ENDLICHER. 



REGION L THALLOPHYTA (fexxfc, frond $**,, a plant). No opposition 

 of stem and root. No spiral vessels, and no sexual organs. Pro- 

 pagated by spores. 



SECTION i. PROTOPHYTA fax, first or originating). Developed without 



soil; deriving nourishment all around; fructification indefinite. 

 SECTION n. HYSTEROPHYTA (srn^of, posterior or derivative). Developed 



on decaying organisms ; nourished internally from a matrix ; 



all the organs appearing at once, and perishing in a definite 



manner. 



KEGION H CORMOPHYTA (*. ?/1 *, a stalk or trunk). Opposition of stem 

 and root. Spiral vessels and sexual organs distinct in the more 

 perfect. 



SECTION in. ACROBRYA (*?, summit, and 0$tu, to germinate). Stem 

 increasing by the apex, the lower part being unchanged, and 

 only conveying fluids. 



Cohort 1. Anophyta (,>*>, above). No spiral vessels. Both sexes pre- 

 sent. Spores free within spore-cases. 



Cohort 2. Protophyta. Bundles of vessels more or less perfect. No male 



organs. Spores free within one- or many-celled spore-cases. 



Cohort 3. Hysterophyta. Both sexes perfect. Seeds without an 



embryo, consisting of many spores. Parasitic. 



SECTION iv. AMPHIBRYA (^i, around). Stem increasing at the circum- 

 ference. Vegetation peripherical.
