Xvi. GENERA OF FEENS ! 



under surfeoe of the disc-lite fertile fronds. Veins flabeUately- 

 fiircate ; venules free. 



Fronds small, dimorphous ; the sterile flabellately-partite, or 

 ouneato-dichotomoos, the fertile entire or two-lobed. Bhizome 

 slender, creeping. — Curious little creeping plants with divided 

 barren and entire fertile fronds. 

 Ex. : E. flabeUata, Fie. | E. peltata, SchoU.

ACEOSTiCHtiir, Fie and Ajict. ; Phtujtis, Necker ; Olpebsls sp., Freal. 



Sori superficial, non-indusiate j the receptacle occupying the 

 under surface of the fertile scarcely contracted fronds. Veins 

 simple or paraUelo-furcate from a central costa ; venules free, 

 davate at the apex, terminating within the margin. 



Fronds simple, entire, the fertile often somewhat narrower, 

 naked or clothed with scales. Khizome short, erect or decum- 

 bent, or elongately creeping; rarely humifuse and ramose. — The 

 name Acrosiichum, which M. Fee retains here, is properly asso- 

 ciated with A. aureum, the Liansean type. The present is a well 

 marked genus, the analogue oi Scolopendrium ; hence, M. Schott's 

 very appropriate name, JBlaphoglossmn, which we adopt. 

 § Oligolepidum: — Fronds naked, or witli but few scales.
