under surface of the disc-like fertile fronds. Veins flabellately- 

 furcate ; venules free. 



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

 cuneato-dichotomous, the fertile entire or two-lobed. Khizome 

 slender, creeping. Curious little creeping plants with divided 

 barren and entire fertile fronds. 



Ex.: E. flabetlata, Fie. \ E. peltata, Schott.

 ACBOSTICHUM, Fee and Auct.; PHYM.ITIS, NecTcer; OLFEBSLS sp., Presl. 



Sori superficial, non-indusiate ; the receptacle occupying the 

 under surface of the fertile scarcely contracted fronds. Veins 

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

 clavate at the apex, terminating within the margin. 



Fronds simple, entire, the fertile often somewhat narrower, 

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

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

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

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

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

 very appropriate name, Elwphoglossum, which we adopt. 

 Oligolepidum. Fronds naked, or with but few scales.
