134 CLABOPHLEBIS. 



Family ? POLYPODIACE^. 



Genus CLADOPHLEBIS, Brongniart. 

 [TaUeau, p. 25, 1849.] 



1. Cladophlebis denticulata (Brongn.). 

 [2. Cladophlebis lobifolia (Phillips). 

 3. Cladophlebis haiburnensis (Lindley & Hutton).] 



The species Cladophlebis denticulata (Brongn.) is included in 

 the family Polypodiacese on the ground that the fertile pinnules 

 agree fairly closely with those of some recent polypodiaceous ferns, 

 but the evidence is insufficient to admit of a positive statement 

 as to systematic position. The other two species of the genus 

 must still he included among the ferns which do not afford any 

 trustworthy evidence as to family affinities.
