Cor dai tales. 
Phylum Cycadophyta. Nathorst, 1902. 
Megaphyllous ; leaves compound; stems phyllosiphonic ; with pri- 
mary roots; ciliated sperms. Gymnospermic and strobiloid. 
Including Cycadales, Williamson iales and Cycadeoidales 
(Benettitales). 
Phylum Pteridospermophyta. Ward, 1904. (Cycadofilices of Potonie, 
1902). 
Megaphyllous; phyllosiphonic; spermophytic, cf and 9 sporophylls 
little differentiated from the vegetative f oHage ; gymnospermic but 
never strobiloid; filicinean in form and habit and much of their 
vascular anatomy. Including Cladoxylaceae, Lyginodendraceae, 
Medullosaceae, Cycadoxylaceae, Protopityaceae and incertae 
sedis including Aneimites, Gigantopteris, Glossopteris, etc. 
Phylum Lepidophyta (XeTrts, ibosj a scale). Berry, 1915. 
Microphyllous ; cladosiphonic, with exarch pro tostele ; homosporous, 
heterosporous and quasi spermophytic. Prevailingly strobiloid.

Phylum Arthrophyta {apdpov, a joint). Berry, 1915^ 
Stems articulated at the nodes, ribbed. Leaves verticillate, dich- 
otomously compound in the Pseudoborniales and the Protocal- 
amariaceae, palmately laciniate in some Sphenophyllales ; pro- 
* There is a question whether these two groups with possibly the Cordaitales should not 
be united as an independent phylum intermediate between the Coniferophyta and the 
Cycadophyta. 
t The Lepidophyta correspond to the Lycopsida of Scott except that he refers the Psilo- 
tales to his Sphenopsida (Scott, 1909). 
X Nearly equivalent to the Articulatae of Lignier and the Sphenopsida of Scott.
