i62 ONOCLEOID FERNS [ch. xliii 



conclusion is inherent in the above pages that the Onocleoid Ferns are best 

 regarded as forming a separate phyletic offshoot from some Cyatheoid source, 

 and should accordingly be constituted a distinct Tribe, as the ONOCLEEAE. 

 The phyletic grouping of the living Onocleoid Ferns that have been here 

 examined should probably be as follows: 



ONOCLEEAE 



I. Non-indusiate: open venation. 



Matteuccia mtcrmedia C. Chr. 



II. Indusiate: open venation. 



Matteuccia strutJiiopteris (L.) Todaro. 

 Matteuccia orientalis (Hk.) Trev. 



III. Indusiate: reticulate venation. 

 Oiioclea sensibilis Linn.
